CS BEAM OVERVIEW

CS Beam is a beam design application that performs single member sizing analysis to determine the most efficient material for beams, headers and joists based on specified design criteria. The first time using CS Beam , it is recommended that the program Presets be modified, since load analysis is based on a series of user-defined settings.

CS Beam Main Screen





PRESETS

Presets are user-defined settings applied by CS Beam in specific situations. Program presets define default program values, set deflection criteria, establish vibration conditions, set the preferred framing member analysis approach, as well as a variety of other tasks.

Clicking the Presets icon or selecting Edit > Presets displays the Presets window.

Skip loading, also known as “Checkerboard” or “Pattern” loading, applies to multi-span roof members and is used to evaluate the member for the effects of partial loading. When checked, roof live loads are applied to adjacent and alternating spans to evaluate any live load or snow load arrangement that may create more unfavorable shears, moments or deflections than those determined for the fully loaded beam.

IGNORE POINT LOADS ON BEARINGS FOR GIRDERS

Check to ignore point loads over bearings when analyzing girders. When checked, point loads are not applied during girder analysis, assuming the point load transfers through “squash blocks” or other alternative framing to the bearing below.

BEARING LENGTH FROM POINT LOAD OF TOP LOADED BEAMS

This is the assumed bearing length at the top of the beam of any concentrated load applied over a bearing. This value is used only in the “Secondary Bearing Length Check”. It should be the width/length (measured along the beam) of the wall or column (above the beam) that is applying the concentrated load. Entering a larger value will increase the capacity used for the “Secondary

Bearing Length Check”.

Design Overrides Tab: Bearing Length from Point Load of Top Loaded Beams

Ì NOTE: This setting is used with Canadian codes only.

USE TOTAL BEAM WIDTH FOR UNBRACED LENGTH CALCULATIONS OF

MULTIPLY MEMBERS WITH DEPTH-TO-WIDTH RATIOS > 2.5

When checked, the analysis for “beam lateral buckling” will use the full beam width/thickness instead of the ply thickness for “b” in the calculations. This will have an effect on capacity ofor beams that are NOT continuously laterally braced. Having this checked can greatly increase the calculated unbraced bending capacity, and the capacity of a multi-ply beam will match that of a solid beam of the same total width.

Ì NOTE: This setting is used with Canadian codes only.

Highlight a specific Fastener Option in the list and then click Move Up and Move Down to prioritize the list.

Fasteners are analyzed starting with the first entry, then progresses down the list until a fastener configuration option meets the specified design criteria. For example, if ½” diameter bolts are listed at the top of the Fastener Option list, no matter how small the applied load, the program will specify a bolted multi-ply connection even though nails or screws might have been sufficient based solely on the applied loads.

Click Delete to delete a fastener line item from the available Fastener Options list.

Design Overrides Tab: Fasteners Window

Click Add to add a new fastener type from the available options and configurations.

Ì NOTE: There are no on-center spacing options listed for the SDS or SDW screws. For these two fastener options, the required spacing will be calculated based on the applied loads and results reported on the calculation sheet.

Also when all three configuration options are selected then all three items will be added to the

Fastener Options list and will be considered during analysis.






Ì NOTE: The fastener list in the figure above is not ordered based on lateral strength.

The order of the fasteners in terms of lateral strength, least to greatest is as follow:

•

0.122 x 3.25” spiral nails (approximately a 10d sinker)

•

0.131 x 2.5” nails (8d common)

•

0.131 x 3” nails (8d common) same lateral strength, only the lengths are different

•

0.131 x 3.5” nails (8d common)

•

10d common nails (0.148” dia.)

•

16d spiral nails (0.148” dia.) same lateral strength, lengths and/or shapes are different

•

16d sinker nails (0.148” dia.)

•

16d common nails (0.162” dia.)

•

½” diameter bolts

•

SDS screws

•

SDW screws (the calc. sheet notates that the screw is to be installed from the loaded side, as required)

In order to include the fastener requirements for multi-ply connections on the calculation sheet, check Report Fasteners on Calc Sheets. Leave unchecked to not report multi-ply connection information on calculation sheets.

Fastener information will be included in the Product section of the calc. sheet.

Member Description Tab: Member Type

A beam is any member dropped below an area to support that area’s structural members.

Although a beam can be placed flush within a floor or roof system, a method is required to differentiate between flush and dropped conditions. Window and door headers are classified as beams.

Beam





A girder , commonly referred to as a flush beam, is any flush member within a system that supports other structural members. A rafter or joist is also a flush member, but in the confines of the Structure program, they do not support other load-bearing elements.

Girder

Joists are repetitive on center spaced members used within a CS Build defined area. Rafters are considered joists when used in a roof system.

DESIGN SPAN EVALUATION

CS Beam evaluates bearing lengths in the following manner:

For members supported by walls, the design span subtracts the width of the wall and adds 7/8”. For example a 12’-0” girder supported by 2x4 walls at each end would have a design span of 11’-6 ¾” (12’-0” minus 7” for the bearings, plus 7/8” for each bearing).

For members supported by girders, the design span subtracts the entire width of the girder. For example a 12’-0” member supported at each end by 3 ½” wide girders would have a design span of 11’-5” (12’-0” minus 3 ½” for each bearing).

For simple span members with a cantilevered end, the bearing moves to the exterior face of the wall and the 7/8” correction is omitted when determining design span.

For multiple span members, the design span extends to the middle of the interior bearing. For a 24’-0” member supported by 2x4 walls at each end and at midspan, the two design spans will equal 11’-9

3/8” (12’-0” span from the exterior bearing to the middle of the center bearing minus 3 ½” plus 7/8” correction for the exterior bearing).




ADDITIONAL LOAD

An Additional load adds to the Standard Loading specified on the Member Description tab.

For example, a floor girder with Standard Loading of 40 psf live and 10 psf dead has an

Additional Uniform load added of 80 plf live and 30 plf dead. The total applied load would be 160 plf ((40 + 10) + (80 + 30)).

Loading Tab: Member Data





REPLACEMENT LOAD

A Replacement load adds the new loading and removes the Standard Loading in the area that the Replacement Load is applied. For example, a floor girder with Standard Loading of 40 psf live and 10 psf dead has a Replacement Uniform load added of 80 plf live and 30 plf dead applied to the entire member. In this case, the total applied load would be 110 plf ((40 + 10) – (40 + 10) +

(80 + 30)).

Loading Tab: Member Data

PLF LOAD

A plf (pounds per linear foot) loading type requires a beginning and ending location and the magnitude of the uniform load.

Add New to edit hole specifications in the window.

Input Interface: Holes Tab





Select Rectangular , Circular , or Duct Chase hole from the Shape list. A Rectangular hole requires a width and a height, a Circular requires a diameter, and a Duct Chase requires a width.

Ì NOTE: If 0 is entered for the width of a hole, the maximum allowable hole size will be calculated at that location.

Holes Tab: Example Hole

PRODUCTS TAB

The Products Tab lists all products being considered for the designed member. Select a viable product from the Product List window and make a selection from the Plies window to specify the number of plies for that solution. The number of plies initially displayed is the most efficient design for that Product. Products that show “0 ply” do not have a solution. For Edit Product List, refer to the detailed instructions in the Presets Defaults Tab section of this manual.
