1 TB-35 March 017 (Expires 3/019) Select Beam Design Tables The following information is intended to assist building designers and/or building officials in selecting appropriate Trus Joist beam products. The tables have been drafted to be similar to the span tables found in Part 9 of the National Building Code of Canada (NBC) 015 and the Ontario Building Code (OBC) 01. It is the responsibility of the building designer and/or building official to confirm the conditions of the beam to be within the limitations of these tables. The tables included in this technical bulletin provide maximum load solutions for select and. The member widths considered are 1 ¾, 3 ½, 5 ¼, and 7. The member depths considered are 9 ½ and 11 ⅞. The tables encompass four different design loads. For each design load, three different load configurations are considered. The first load configuration involves only a uniformly distributed load. The second and third load configurations involve a standardized uniformly distributed load combined with a single concentrated load that is located within a specific region along the beam span. It is important to note that the values in these tables apply to only simple span beams. For continuous spans, cantilevers, and other applications, use Forte software by Weyerhaeuser. For additional design information, including multi-ply connections, please reference Specifier s Guide for Trus Joist Beams, Headers, and Columns (Canada-East: TJ-9500 \ Canada-West: TJ-9505). Should the building designer and/or building official have any questions, please contact your local Weyerhaeuser representative.

The design example considers two () beams with unique loading conditions. It is intended to help interpret the tables and encourage ease of use for building designers and/or building officials.

2 TB-35 March 017 (Expires 3/019) How to Read These Tables The content within a cell varies depending on the load configuration. The figures below illustrate the type of information contained within a cell for each general load configuration. UNIFORMLY LOADED BEAMS Maximum Supported Length Minimum Bearing Length (Column or Hanger / SPF Plate) [in] CONCENTRATED LOAD (DESIGN LOAD AREA) FOR BEAMS Maximum Concentrated Load [lb] Design Load Area [ft ] Minimum Bearing Length (Column or Hanger / SPF Plate) [in] Minimum Bearing Length Adjustment for SPF Plate The tabulated values for supported length, concentrated load, and/or design load area assume the beam is bearing on either an SPF column (No. or better) or x SPF plate (3.50 maximum plate width). If the actual value for supported length, concentrated load, and/or design load area is less than the tabulated value, the minimum bearing length for SPF plate may be reduced. For the supported length tables, the reduced minimum bearing length (LL bb ) is a product of the load ratio and tabulated minimum bearing length. For the concentrated load tables, the equation for reduced minimum bearing length is given in the table below. It is important to note that the minimum bearing length for all Trus Joist beam products is 1.50 regardless of the load conditions.
