The whole of the products and manufactures of the
Company are dealt with.
The rolled sections conform
to the requirements of the New British Standard Sections
determined by the British Engineering Standards Associa. tion in 1924.
The computations of the data have been carried out
by our own' staff and will be found to be in accordance
with the best modern practice.
Tne accuracy attained m the calculations enables
us confidently to recommend the use of the, book to
Architects, Engineers, and all those engaged in Bridge

GENERAL NOTES.
STEEL.
All. Dorman, Long & Co.'s steel is manufactured by
the BASIC OPEN HEARTH Process, which ensures a
reliable and uniform product.
TESTS .
The Company's standard product will give the followmgresults under test : 28/33 tons tensile stress per square inch.
20% elongation in eight inches.
.
40% reduction of area at point of fracture.
•
The Steel meets the requirements. of His Majesty's
Government, British Standard Specifications, The London
County Council, Lloyd's and other surveys, 'and Railways
at home and abroad.
STRESS .
. There has been in recent times a tendency towards a
somewhat increased tensile strength of steel; the British
Engineering Standards Association . has already raised its
upper limit to 33 tons per ' square inch.
•
I
Under these circumstances, the tables given in this
Handbook are based on a safe extreme fibre stress of 8 tons
per square inch) this bei~g, in the Company's experience,
a perfectly.safe limit.
SPECIAL STEEL.
Such as Copper Bearing Steel, Admiralty liD" and
i, D.' 1," and oth~r High Tensile Steels, can be supplied
to meet Customers' requirement~.·

ROLLING MARGINS.'
The usual Trade margin is claimed in rolling sectional
material, namely 2~% above or'below the dimensions and
weights listed.
Sections, whether from rolls or stock, are cut to a
margin of 1in. over or under specified lengths.
An extra
is charged for cutting to within Mn. of exact length, and
for machining square.'
BRITISH STANDARD SECTIONS.
Full information as to the dimensions and properties
of the New British Standard Sections is given, and a wider
range of tables will be found in this Handbook than in the
,
Company's previous publicq.tions.
Some time will, of course, elapse before the New British,
Standard Sections are adopted generally, and some of the
Old British Standard Sections will be on the market untif
the rolls for these sections ate out of use. It is, therefore,
necessary in the prynt issue to give particulars of, the
old as well a,s the new sections.' Particulars of the olet
sections are printed on PINK PAPER to enable them readily
to be found and distinguished from those of the New British
Standards. Other sections, which have on occ.a sions been
"
'
rolled by the Company to meet a special demand, will also
be found on the pink paper.

COAL SHIPPING PLANT.
In order to save the necessity of vessels thC1.t 'bring
cargoes of raw materials to Middlesbrough having to proceed to other ports to load return cargoes of Coal ' or Coke,
the Company has just completed a modern Coaling Plant
capable of bunkering and loading steamers up to 6,000 tons
capacity with four holds, :~ without movement.
This Plant is situated at the Company's Port Clarence
Wharf on the North Bank of the River Tees.
'.

,
DORMAN, LONG & CO. LIMITED.
The Plant is of latest design and effici~ncy, and 15
capable of Shipping at the rate of 500 tons of Coal or 300
tons of Coke per hour; thus immensely improving upon
the facilities which have hitherto existed in the river, and
offering vessels the quickest possible despatch.

NOTES ON SECTIONS.
REFERENCE MA~KS.' The ref~rence marks determined
by the British Engineeririg Stan4ards Association for
the neW British Standard Sections have been generally
adopted 'tl1roughout this work as a ready means of
identification, but other sections for which rolls are still .
available and those to meet special demand, which are
tabulated on the pink pages, retain the reference marks
given in our, previous issues of the « Pocket Companion."
WEIGHT OF STEEL-All calculations fot weights are
based on a piece of steel one square inch sectional area
and one foot long, weighing 3·4 lbs., or one ,cubic foot
of steel weighing 489'6 lbs.
MODE OF ORDERING MATERIAL.' Beams, Channels
arid Bulb Angles should, be specified according to the
weights per foot given in the -diagrams and tables, Rails
to the published weights per yard, but Angles, Tees, Flats,
etc., to the thicknesses required.
VARIA nONS F~OM PUBLISHED WEIGHTS OR THICKNESSES.-The minimum weights' or thicknesses given
on the diagrams and tables cannot be decreased, but may
be exceeded if the tonnage ordered is sufficient to warrant
a change being made; the effect upon the profile being
as indicated on page 55. '
It should be observed, however, that such change is
,only of limited extent.

NOTES ON BEAMS AND COMPOUNDS.
,I I
I
'DIMENSIONS AND
PROPERTIES~-The
dimensions and
properties of beams will be found on pages 58 and 59.
The dimensions and properties of compounds are
,
;
i
given on the pages immediately preceding those containing the tabular loads.
The moment of inertia and
, section modulus have been calculated in inch units on
the net section, that is both flanges holed for rivets, the
size allowed in any particular case being shewn
in the
,
several tables.
WEIGHTS OF
COMPOUND~. -The
published weights per
foot of compounds a.re inclusive of rivets.
The pitch
of rivets fQr spa.ns in general demand has been taken as
the basis of calculation in all cases.
TABULAR LOADS.-The loads given in the tables include
the weights of the girders themselves, and are based on
an extreme fibre stress of 8 tons per square inch. They
are also calculated on the assumption that the girders
receive the usual side support as in building work. For
other cases, such as concentrated, eccentric, or live loads,
special calculations are necessary.
The resistance of the web to shear or buckle has
been taken as the
limiting factor in deciding the
maximum load for each section.
These loads should
not be exceeded when sections are used at less spans
than those for which such values are given.
DORMAN, LONG &
CO. LIMITED.
=
It will be noted that, m many cases, several com-
pounds of different c;lepths and widths will meet the
requirements as to loading. It should, however, be
borne in mind that, where the depth is not restricted,
a deeper and frequently a lighter section, carrying even
a greater load than that required, may often be found
more economical.
DEFLECTiON .-Care should be taken in selecting beams
and compounds that the deflection is not too great for
the purpose for which they are to be employed.
zig-zag lines in
~he
The
tables indicate the generally ac-
cepted limit of span to depth (20 to 1) for girders supporting plastered ceilings at full tabular loads.
For beams and compounds, of unifoml section
throughout their lengths, a table giving the deflections
m inches for tabular loads will be found on page 110.
If the a~tual load is less than the tabular load, the
deflection will be less in exactly the same proportion.
RIVETING OF COMPOUNDS.-In the tables of compounds,
, particulars are given of the diameter of rivets for each
'section, together with the minimum spans, at, and
above, which the varipus pitches may be used for uniformly distributed dead loads. In cases of spans shorter
than those for which loads are given, as also for con-
•
centrated" eccentric, or live loads, special calculations
,are necessary.

CRIPPLING LOADS.-A table shewing.the crippling loads,
in tons per square inch, on stanchions and struts
with fixed ends, for various values of . ~ . up to 200, is.
given on page 117.
,
"
TABULAR LOADS.-The safe loads given in the tables
- are based on the crippling values above referred to,. for
the least radius of gyration for each section; the factor " .
of safety adopted being· 4. They are for stanchions' or
:
.
struts the ends of which"may be considered fi~ed, · and .
only apply to static and concentric loading;
.
,
~
"
~
.
In preparing the table of safe loads on latticed
stanchions, it has been assumed that the component
beams or channels are efficiently connected together by
lattice bars, or batten plates, so that they act as a unit,
thus eliminating all possibility of failure by local flexure
of either beam or channel. .
.
,
I
.
EFFECTIVE LENGTH.- In stanchions or struts having
intermediate steelwork connections,
so arranged
as to'
I
..
prevent side flexure where these connections occur, the
effect is such that the load transmitted .may be con .. .
.
.
sidered as acting on the shortened length, and t~ "
•
section determined accordingly.
~
LIMITING LENGTHS FOR TABULAR LOADS.-The
maximum . lengths for which loads 9-re given are bas·e d
on the lesser of the two values : 1.- 160 times the least radius of gy~ation ..
II .- 40 times the least width of· the section.

TABULAR WEIGHTS OF STANCHIONS.-The weight
given in the tables, for each section, is for the shaft,
inclusive of rivets; the pitch of ri,,:ets for lengths in
general demand, being taken as the basis of calculati.on
in all cases.
The weights of base, cap and fittings are not included, as they depend on the loads and type of structure.
PROPERTIES OF SECTIONS.- The section moduli, radii '
of gyration and area are given for each section. The
section moduli will be or service when calculating
additional stresses' due to' wind-pressure, eccentric
loading, or" other forces producing bending.
CONDITION OF ENDS.- Under ' some conditions it is
necessary to consider either one or both ends rounded.
" The f~l1owing method
be found sufficiently accurate
for ascertaining the approximate safe loads. In the
" case of one' end fixed and the ~ther rounded, the approxi, mate load may be found by referring.in the table of safe
loads to a length of 1 t times the actual length; whilst
with both ends rounded the reference length should be
1 i times the actual 'length.
EXAMPLE.-For a stanchion or strut 12 feet long
with .one end fixed and one end rounded, referen<;e
should be made in the table of safe loads to a length
of 16 feet, or, if both ends are rounded, to a length of
20 feet, when the respective safe loads will be found.

TYPES OF BASES, CAPS, JOINTS, AND GIRDER CONNECTIONS TO STANCHIONS;- , Various types of bases,
caps, joints, and girder connections to stanchions are
illustrated. In all of these, due consideration h~
beeri given to ensure efficiency' and simplicity of
design.

BEAM GRILLAGES FOR STANCHIONS.-For stanchions
. supporting heavy loads, the necessity for deep excava-',
tions and large masses of masonry in foundations,
may be considerably reduced by the adoption of sui~able
grillages, combined with stanchion bases, carefully
designed to transmit the load.
.
These are generally obtained by placing on a layer
of concrete, one, two, or three tiers of beams, accordoing
to the load to be distributed, and the bearing 'capacity, __
of the ground. The beams in each tier should he kept '
sufficiently far apart to allow of the iritervening spaces·,
being thoroughly filled with concrete. In cases where
two or three tiers are found necessary, they should be
efficiently secured to each other, and the stanchion base
to the whole.
The following diagram illustrates a grillage, Gonsisting of two tiers of beams : -

The ·o'Verall dimensions of the lower tier are determined by the bearing capacity of. the ground, and to
find the section of beams required in any tier :.,
Let W = totalload in tons supported by the stanchion.
n = number of beams forming the tier.
w

W

n
L = length in feet of each beam.
l. = length in feet, at central portion of beam, over
which t~e load above it is distributed.
M = maximur(bending moment in foot tons, in one
beam (this occurs at the c~ntre of length L).
.
Then M

The above bending m9ment is .equivalent to that
produced ina beam supported'at both ends, an~carrying
a distributed 10C\.d w over a. span = L - t. Therefore,
. on reference to this span in the tables of safe loads, given
on pages 72 and 73,· the si~e of beam to carry the load
'w may be obtained direct.
It should be observed, however, that for reasons
given on page 70, under the heading « Tabular Loads,"
the load w should not exceed the maximum load, given
In the table, for the section decided upon.
grillage has to be provided for a
stanchion, on ground having a bearing capacity of
2 tons per square foot, the total load to be supported
being 120 tons; · assurned size of stanchion base, 2 ,
feet square.
For above load and bearing capacity of ground,
two tiers will suffice, and as the area required for the
foundation is 60 square fee,t, the lower tier will require

to be about 8 feet square j therefore, in this tier, ten
bearris can be placed side by side at 10 inches centres,
the load w on each being about ¥ff- or 12 tons.
The bending moment in ,each beam is equivalent
to that produced by this load uniformly distributed
over a span of L - 1 = 8 - 2 = 6 feet, and referring
to table of safe loads on page 72, it is found that
N .B.S.B. 7 (8" X 4" X 18 Ibs. per foot) is a suitable ' section for the lower tier.
The upper tier will be 2 ieet wide, i.e., the width of
the stanchion base. In this width .three
beams can. be

.
placed side by side at 9 inches centres, the 10a4'won
each being about 11.Q. = 40 tons , whichisto 'betaken as '
uniformly distributed over a span of L, ,-' t ,= 6 feet, arid
on reference to the table of safe loads as t>efore, it will
be found that N.B.S.B. 12 (14/1 x 5~" X 4:0.1bs. per foot) ,
IS a suitable section for this tier,.

.
.
The above analysis involves the usualJundamental
assumptions pertaining to flexure,
The exact conditions involved in these assumptions
are not usually obtained in . grillage practice, so that
results obtained by the above analysis should ,be care- :
f,u lly interpreted.
Our own practice 10 designing grillages
lines of the above analysis.

Where the loads transmitted are vet; larg~, the
grillage requires special designing, and in such 'cases" '
particular attention should be given to the 'sections of ·
' the beams with reference to their ability

loads involved without crippling of the webs.

" Bolted Connections '" may be adopted to iacilitate erection, if found advisable,
. .
DORMAN, LONG & , CO. LIMITED.
STANDARD CONNECTIONS
FOR
STANDARD·
ANGLE
BEAMS.
CLEATS.-The· standard
angle
cleats,
illustrated on pages 166 to 169, have been designed
C·,
for bolted site connections. . They have als.o been
calculated to withstand reactions equivalent to those
produced by the tabular loads on the beams at the
minimum spans given with each standard connection.
Where the reactio~s are greater than the above,
additional support,
necessary;
or special connection, will be
on the other hand, modification may be '
qeemed desirable when the spans exceed the minimum,
I
or where the beams rest on brackets capable of
transmitting the reactions.
SEPARATORS.-When two or more beams are required
to be holted together, side by side, to form a girder,
cast iron or pressed steel separators are frequently
used.
They should be placed at intervals of about
five or six feet, and where concentrated loads occur.

NOTES ON
CO. LIMITED.
PLATE GIRDERS.
GENERAL NOTE.- On the preceding pages, tables of
beams and compounds are given, shewing the loads
carried by each for various spans; but under some
conditions, as for instance .where the deflection allowed
is very small, it will sometimes be found that the plate
girders, given ii1 the following pages, may be used with
advantage . .
TABULAR L"O ADS.-The loads giv~n in the . tables' inc1~de
the weights of the girders themselves, and are,' in each
case., calculated from the modulus of the net section,
i.e., both flanges holed. They are based on an extreme
fibre stress of 8 tons per square inch .
. When it is considered advisable to adopt any o):her
extreme fibre stress, say f tons per square inch, the
tabul~r loads should be altered . in the ratio -{.
,The loads are also based on the assumption that
the girders receive efficient lateral support, and the webs
are adequately stiffened.
,
.
STIFFENERS.-The stiffening of plate girders may be
effected by means of vertical angles fitting between the
.
inner surfaces of the flange angles, and properly riveted
to the web. In the case of girders having double webs,
diaphragms may be adopted, which ensure greater unity
than that obtained by using outer stiffeners alone. The
spacing of the stiffeners depends on the depth 'of the
girder, the thicknesses of web plates, and the purposes_
for which the girders are required.

Table of Coefficients for the determination of StressM, and Lengths of Members,.In Rool
Trusses, for any span, the proportion 01 height to half the span Iielng i : 2'_
. To find the Stress in any MembcI::~
Let S=Span between the points of intersection of the Rafter and Tie_
L=Total Dead Load carried by the Tr uss, including its own weight.
W ='T(ltaJ Wind Pressure resisted by tbl< 'Truss, acting on one s~e of roof,. and .
normal to its surlace,
f=Total Stress re~uired _

.
Then f= (L multiplied by Coefficient for Dead Load) + (W multiplied by Coefficientfor Wind Pressure) _
* In Trusses of larger spallS it h sometimes advisable to provide for expansion,
in which case the co;otlicient fQ.r wind pressure corresponding' to "one
end free" sholl)el be used.
To find the length of any Member betwf,en points of jntersection:Multiply S by tbe lengtb coefficient f()r that member.
.
N o.T&,-The following Stress Coefficients hav.e been calculated on tbe n,"umptioll that
the roof pllrlins occu):' OVer the points 6f intersection of the v arious rnembers with
the rafter; when such is not the case, bending is produced ill the rafter which

ROLLED
TROUGH ING.
TROUGH lNG, as illustrated on the following pages, can be
.•
recommended for a varfety
a f purposes.
'"
v v hen used
for road' bridges, it not only affords a watertight superstructure for carrying the road metalling, but, in most
cases, dispenses with the use of cross girders and
frequently with the main girders also .
In railway
bddgesit frequently takes the place of cross girders,
railbearers and tiinber planking i
at the same time
forming a safer floor in case of derailment. A maximum
amou.n t of headway under the bridge is attained, and a
. saving in cost effected. The. smaller sections will be
•
found especially .useful for the decking of piers, floors
0,£ warehouses, ceilings pf subways, strong rooms, etc.
The t~'oughing is usually riveted, before dispatch,
in !?ections of three, thus ;-.
The site . connecti'o11s are generally made with rivets,
butbQlted connections may b~ adopted wherifound
. . .
advisable i
r
ei'i:her method affdrdihg easy f'means of
erection.
Single troughs, as illustrated on pg.ges 49 and ' 50,
are frequently used as roof gutters, aTid permit of the
supports being placed at long distances apart .

Example shewing how to find the size of
a beam necessary to carry three loads
concentrated at different points in its
Jength, as shewn ill diagram; the
beam being supported at both ends,
and 'of uniform Cross section throughout.
Let Wi' W 2 and W u be 3 concentrated
loads of 2,3 and 12 tons respectively,
R, = reaction at end S.
R" = reaction at end T.
W];; = ' equivalent distributed load
over . the whole beam which
would produce the saine maximum bending moment as that
caused by (W 1 + W 2 +W 3)'
+ (3 16

+ 3 +2
X 14) _ 7 t . ·
ons.
- 7 = 10 tons.
The maximum b~mding moment occurs at the point of applic?-tion of
one of the loads, a,nd may be found as follows :' -
•
The bending moment at C = R, X 2
= 7 X 2 = 14 ·ft. tons.
"'
,,
,, ' D = R, X 8- 2 x 6= 56 - 12=44 "
"
"
."
E = ,R" X 5
= 10 X 5=50 "
Hence the maximum bending moment is a.t E, and = 50 ft, tons.
The maximum bending moment, in ft. tons, on a beam supported at
'both ends and having an uniformly dist.ributed load, W, is WaL.
'Therefore the equivalent t _ Maximum bending moment in ft, tons X 8,

Reference to the table of safe distributed 10ll-ds on beams will shew that
N.B.S.B. 14 (16/1 x6" x 50 Ibs.) is capable of carrying 25 '8 tons at
16 feet span; and, as half the maximum load given in the table for

Iu the above tables double shear is calculated at twice single shear; and the beo.ring
stress per square inch at twice the 'shearin'g stress,
The bearing values above and to the right of the upper zig-zag bnes ill the tables are
greater tban ,double shear for the corresponding diameters, so that in these cases the
sbearing values are the 'determining factors ,
,
The beating values between the ,lower arid upper zig,zag lines are greater than single
and leS$ than double shear for t.he c()rresponding diameters, so tbat in ' the case of single
shear the, sheaJlng value is the determining, factor, and in the case of double shear tbe
bearin,g value is the determii)ing factor,
The bearing values below and to the left of the,lower zig,zag lines are less than single
,
s)leal', so that in t.heS,e cases the bearing va.lllesare tbe determining factors,

Process of Manufacture.
IJ. steel shall be made by the Open Hearth Process (Acid or
Basic), unless either process is required or specified, and shall
not show on analysis more than 0·06 per cent. of Sulphur or of'
Phosphorus.
.
. B steel may be made. either by the Open Hea.rth Process (Acid.
or Basic)., 01' by the Acid Bessemer Process, and shall not show
on analysis more than 0·08 per Cent. of Phosphorous, and not mOTe
than 0·06 per cent. of Sulphur.
N o'r£.- 8 steel is not intended for BriClges, P.hJtes t inch in ttiickness and over,
Rivet B<lrs, or for He,\t Treated Wire.

.
Quality of Finished Stee1.
All finished steel as sent from the mills shall, subject to the
provisions of Clause 17, be well and cleanly rolled to the dimensions,
sections and weights specified 01' required. It shall be sound and
free from cracks, surface flaws, laminations, rough, jagged and
imperfect edges, and all other defects, shall be finished in a workmanlike manner and shaH in all respeGts comply v'vith the tests
and requirernents, herein mentioned, applicable to the description
of. material (e.g., plates, sect.ions, bars, rivets, etc.) required or
specified. .
.
3. .Tensile Test Pieces.
, The tensile strengtl), and elongation of all steel shall be deter··
mined frorn Standard Test Pieces cut. lengthwi.se and crosswise
froni plates, ane! .lengthwise from sections and bars.
The test pieces shall not be annealed, or otherwise subjected
to heat treatment, unless the material from which they are cutis
simllarly , treated, in "hich cas.e the test pieces shall be similarly
and simultaneously treated with the material before testing .
Any straightening of test pieces which may be required shall
be done cold.
The rolled surface of the steel wherever practicable shall. be
retained on two opposite sides of the test piece, but in the case
of bars having diameters or sides not exceeding 3 inches (76·20 rom.)
the bars may be reduced by machining. For bars having diameters
or sides ·above; 3 inches the test piece may, at the· option of the
Maker; be taken from the position shown in the sketches.

. . ' The widths of the test pieces for plates were selected to IOP mply
With the t wo followmg condItions. (I) As the great bulk of"plates
to be tested are from i inch to incH (9·53 to 22'23 mm.) thief; it
was deSirable for the sake of convenience that the test pieces for
such plates should be of uniform width, and , in accordance with very
general practice, a width of 2 inches (50·80 mIll.) was selected .
(2) With a test piece of ;-\ givCIl form, the percentage of elongation
was fOl.lndto be less.for thick plates than for thin ones ; with steel
of the same quality in other respects it was desirable therefore
to choose widths of test pIece '\~hich would be slightly in fa vour
of the' thicker plates. This IS secured with the widths selected
for the Standard T est pi ece of form A .

'upon, these three forms are very nearly similar, and, for a given

In some testing machines it was found inconvenient to use
form B for bars of over I inch (25,40 mm ,) in diameter, and
form F of half the gauge length is designed to meet such Cases. '
For a given material the percentage of elongation w~th test
piece F is greater than with t est piece B, and this difference is
provided for in the British Standard Specifications.

OF'
ENOS.
In thecasc of the rounel test pieces B, C,D, E and F, the form
of the ends is to be as required in order to suit the vC\-rious methods
employed for gripping the test piece. When enlarged ends are used
the lengtll of the parallel portion of the test piece must in no case
. be less than that noted on the diagrams,
