INTRODUCTION
STANDARDS
This Canam steel deck publication presents diaphragm load tables based on the North American Specification for the
Design of Cold-Formed Steel Structural Members (CAN/CSA-S136-01) as approved by the Canadian Standards
Association (CSA) and recommended by the Steel Deck Institute (SDI).
WARNING (DISCLAMER )
Although every effort was made to ensure that all data in this catalogue is factual and the numerical values are
accurate to a degree consistent with cold-formed design standards, Canam is not responsible for errors or oversights that may result from the use of the information contained herein. Anyone making use of the contents of this
catalogue assumes all liability arising from such use. All suggestions for improvements to this publication will
receive full consideration for future printings.
DESIGN
The steel deck sheets used for roofs and floors provide support for gravity loads between the joists and/or beams. Once
installed, these sheets can also be used as a horizontal brace and therefore the steel deck acts as a diaphragm.
The fluted deck is equivalent to the web of a horizontal beam of which the flanges are the perimeter structural members
connected to the deck. The span of that horizontal beam is defined by the distance between the vertical lateral load
resisting systems connected to the deck. The secondary elements form stiffeners for the web produced by the fluted
deck. As for normal beams, the deck (web of horizontal beam) must be attached to the perimeter members (flange of
horizontal beam) to ensure transfer of the shear forces.
REFERENCE
The SDI published the 3rd edition of the Diaphragm Design Manual in 2004 based on the results compiled from a series
of tests conducted in the laboratories of the University of West Virginia. The Manual explains the theory behind the
equations, provides examples on how to calculate the shear in the diaphragm, and indicates how to use the load tables.
The load tables show the shear resistance of steel deck diaphragms based on various sheet thicknesses and profiles
using welds, screws, or power-driven fasteners.
DIAPHRAGM TABLES
This catalogue presents the most common diaphragm tables for Canam steel deck profiles utilizing welds or Hilti pins at
the support and screws or button punches at the side-lap. The diaphragm factored shear resistance tables in this
catalogue are derived following the methods of the SDI and the resistance factors of the Supplement 2004 to the North
American Specification for the Design of Cold-Formed Steel Structural Members (CAN/CSA-S136S1-04). The resistance
factor is assumed to be 0.50 for bare deck and for filled concrete slab diaphragms.
CONSIDERATION
The resistance and rigidity of the diaphragm depend upon the geometry, frequency, and type of fastener used to
connect to the structural elements and the side-lap joints. In addition to this criteria, the value and source of the applied
diaphragm shear must be clearly specified on the structural engineer’s drawings. This information will ensure that the
cost, material, and installation of steel deck reflect the structural engineer’s design and that any alternate proposals will
meet the engineer’s requirements.

SIDE-LAP JOINTS
The choice of connectors at the side-lap can influence the deck profile. Some profiles have a similar shape but the
side-lap joints are different. Therefore, the profile must be specified in order to match the connectors according to:
• The shear requirements;
• The project requirements;
• The erector preferences.

Button Punches
A button punch is formed by crimping the interlocking deck side-lap with a special tool called a crimper. The crimper
has a round die that forms a button when it presses the two sides of the joint together to provide shear resistance.

Welding washers should be used for welds at support when the sheet
steel thickness is less than 0.71 mm (0.028 in.) as specified in the
North American Specification for the Design of Cold-Formed Steel
Structural Members (CAN/CSA-S136-01). The use of weld washers for
material thicknesses greater than 0.71 mm (0.028 in.) can affect the
weld quality and tests have proven that they are not required or
recommended. Welding, as well as all other types of connectors,
must always be monitored on site to ensure that the required size is
provided and that the proper procedures are followed.

STEP-BY-STEP DIAPHRAGM
DETERMINE FORCES
THAT
PASS THROUGH
THE
DIAPHRAGM
In Canada, many buildings are designed using the static approach for the
requirements of the National Building Code of Canada (NBCC). Usually, lateral forces on
a building come from live loads such as winds and earthquakes. The NBCC procedures
define the dead and live load combinations that must be considered. The NBCC design
considerations are beyond the scope of this manual so that proper structural analysis is
required before using Canam diaphragm load tables.
» Forces
Load Path
Connections
Specification
DIAPHRAGM DESIGN METHOD
There are two trends for diaphragm calculation of steel deck; either the Tri-Services approach or the Steel Deck
Institute method may be used. Canam adopted the SDI method since its analytical model is more flexible, it allows the
use of several different types of connectors and it continues to be used in contemporary tests. Also, the method
calculates the diaphragm resistance of the steel deck under its yield stress based on the seismic requirements of the
NBCC (2005).
LIMIT STATES DESIGN
The NBCC (2005) utilizes limit states design exclusively without consideration for allowable stress design.
Therefore, factored loads must be compared to factored resistance for diaphragm design. The North American
Specification for the Design of Cold-Formed Steel Structural Members (CAN/CSA-S136-01) defines the resistance
factor (φd) that is used to calculate the factored resistance of the diaphragm.
OTHER REFERENCE
The 1991 Edition of the Design of Steel Deck Diaphragms published by the Canadian Sheet Steel Building Institute
(CSSBI) was based on an allowable stress design method. In 2006, the CSSBI published the third edition of its
manual based on limit states design with factored resistances for both the Tri-Services and the SDI methods. The
building designer must clearly specify the design method and apply the correct factors to the loads and resistances as
shown hereafter.

DEFINE LOAD PATH
OF
SHEAR FORCES
Shear forces pass throughout the diaphragm from an entry point and are transferred
to the vertical lateral load resisting system (VLLR) through the lateral load resisting line
before ending in the foundation of the building. The load path is controlled by the load type,
building geometry and the location of the VLLR.

LOAD ENTRY POINT
Lateral Load
Lateral wind loads generally enter the diaphragm
from the structural members connected to the building
columns. Earthquake loads, however, are derived from
the inertia of the loads supported by the steel deck.

STEP-BY-STEP DIAPHRAGM
LOAD EXIT POINT
The diaphragm load has to be released to the VLLR. There are a number of methods
involving various structural elements such as:
•
•
•
•
Steel deck puddle weld connections;
Nelson studs in the composite slab;
Shear connectors;
Joist seats.*
Forces
» Load Path
Connections
Specification
* The diaphragm shear load to be transferred by the joist seat must be clearly
specified on the structural drawings by the building designer.
OTHER CONSIDERATIONS
The location of the vertical lateral load resisting elements has an impact on the center of rigidity of the building.
The torsion induced due to the eccentricity between the center of mass and the center of rigidity of the building will
amplify the lateral load in the diaphragm.

STEP-BY-STEP DIAPHRAGM
STEEL DECK CONNECTIONS USING LOAD TABLES
Forces
There are two types of attachments:
Load Path
• Steel deck to the structural elements;
» Connections
• Side-lap along deck sheets.
The steel deck is usually connected to the supports by puddle welds, power-driven
fasteners or screws. This type of connection must be spaced by no more than 300 mm (12 in.)
center-to-center but the actual dimension and spacing can vary depending on capacity requirements.
Specification
Side-lap connections along deck sheets are obtained by mechanical attachments (such as button punching),
screws or welds. The maximum spacing allowed is 900 mm (36 in.) for roof deck and 600 mm (24 in.) for composite floor
deck with smaller spacing required for steel deck used as a diaphragm.
It may be necessary to specify additional connections along the lateral load resisting line to transfer the lateral force
to the VLLR. In this case, the information must be clearly indicated on the structural drawings.

Zone
The zone can be represented by providing a hatched sketch of the entire project or by

Factored Shear
The factored shear for the zone must be specified on the structural drawings.
Deck Profile
The deck profile must be compatible with the side-lap connectors.
For example, the Canam profile P-3606 cannot be used with button punching.
Deck Thickness
The deck thickness is referred to in mm (in.) and not by gauge.
For example: use 1.21 mm (0.048 in.) instead of 18 gauge.
Support Connections
The support connections must specify the type of fastener and the pattern used.
For example:
• 19 mm (3/4 in.) puddle welds with 36/7 pattern (36 in. wide sheet with 7 connectors)
• 12-24 x 11/4 HWH #5 screws with 36/7 pattern.
Note that washers are recommended and should be used when the thickness of the
sheet is less than 0.71 mm (0.028 in.) as per CAN/CSA-S136-01 clause E2.2.

ROOF EXAMPLE
Compute the preliminary design of the roof deck required for a structure, 90 m (295 ft.) long by 38.4 m
(126 ft.) wide, which relies on the roof diaphragm for stability with multiple spans of 1.8 m (6 ft.) and
38 mm (1.5 in.) deck profile. The National Building Code of Canada is the basis for determining the
lateral loads on the structure. Calculation of the lateral loads is not shown here, but the total factored load
due to earthquake loads is given as 712 kN (160 kips) for each lateral load resisting line.

FORCES
The load of 712 kN (160 kips) has been calculated according to the NBCC (2005) and is resisted at the perimeter along
the lateral load resisting lines (lines of perimeter bracings). The shear length is assumed to be 38.4 m (126 ft.) since
there is no opening in the building at the roof and no special requirements are noted to reduce the shear length.

LOAD PATH
Shear Transfer Length
Earthquake loads result from the inertia of the building. Therefore, the lateral load at the roof comes from the
structure’s weight and the superimposed dead and live loads. The load entry point for the roof diaphragm is the structural components. The mass of the building components offers a reaction to the movement of the base of the building
due to the earthquake. The load is assumed to
be uniformly applied at roof and transferred to
the deck at intermediate framing members.
The steel deck transfers the lateral loads to the

CONNECTIONS
Since the shear load is high, welds and screws are utilized to reach the factored resistance. The deck thickness
must be increased to resist the shear load. The P-3606 profile is specified (instead of the P-3615) to ensure the erector
uses screws at side-laps.

NOTES ABOUT LOAD TABLES
STEEL
The diaphragm load tables were derived using Fy = 230 MPa (33 ksi) for Canam’s various types of steel roof decks and
composite floor decks and Fy = 410 MPa (60 ksi) for form deck. For each steel deck design thickness given, factored
design shear is listed under the specific span length and for fastener type and pattern.
CONCRETE
Normal weight concrete is based on a density of 2 400 kg/m3 (150 lb./ft.3) with a minimum compressive resistance
fc’ = 20 MPa (3000 psi) at 28 days. Lightweight concrete is based on a density of 1 840 kg/m3 (115 lb./ft.3) with a
minimum compressive resistance fc’ = 25 MPa (4000 psi) at 28 days.
Both normal weight and lightweight structural concretes on composite and form decks are presented with a minimum
depth of 65 mm (2.5 in.) over the top of the flutes. The diaphragm shear resistance values are limited by the plate-like
shear buckling resistance which governs deck having relatively long spans and closely spaced fasteners.
ASSUMPTIONS
• The SDI Method of calculation is used to develop the load tables and it is a design method endorsed by the CSSBI.
The diaphragm tables were derived based on the following assumptions:
1.
The number of fasteners is the same at the exterior and interior supports.
2.
The spacing of the intermediate side-lap connectors is the same as it is at the outside edge of the building.
3.
Resistance factors are based on the Supplement 2004 to the North American Specification for the Design of
Cold-Formed Steel Structural Members (CAN/CSA-S136S1-04):
φd = 0.50 for welded diaphragm under all load cases;
φd = 0.50 for concrete filled diaphragm;
φd = 0.75 for panel buckling.
4.
All values are based on a three span condition. Greater values are obtained for a single or double span
condition since there are more attached support lines per sheet length available for resistance calculation.
5.
Only screws (for overlapping side-laps) and button punches (for interlocking side-laps) are used to generate
the tables. Welding of side-laps is not recommended for material of 0.71 mm (0.028 in.) or thinner.
6.
Where welds are utilized as fasteners at the supports, the CAN/CSA-S136-01 standard specifies the use
of weld washers for deck thicknesses less than 0.71 mm (0.028 in.). These washers should have a thickness
of 1.5 mm (0.060 in.) and a hole diameter of 9.5 mm (3/8 in.) as utilized for the Steel Deck Institute (SDI)
testing.
REFERENCE
Refer to the most recent SDI Diaphragm Design Manual for the “Limiting Conditions” on end laps, side-lap, welds,
screws, power driven fasteners, split panels, longitudinal edges and mixed panel lengths.
