This structural detail provides truss loading criteria and chord bending requirements for open-web joists, referencing manufacturer drawings for dimensions. The top chord is checked for a 250-pound bending load and features a 3x wood nailer, while the bottom chord is checked for a 200-pound bending load with horizontal reactions indicated as 41.4 kips under Load and Resistance Factor Design. Warehouse areas require an additional point load of 500 pounds at any joint producing maximum truss stress, distinct from standard roof loads. Office areas require an additional point load of 1,000 pounds at any joint producing maximum stress in addition to standard roof and floor loads.
JOIST (SEE MANUFACTURER'S DRAWINGS FOR DIMENSIONS) CHECK TOP CHORD BENDING FOR 250#. CHECK BOTTOM CHORD BENDING FOR 200#. THESE ARE NOT ADD LOADS. WAREHOUSE AREA: IN ADDITION TO THE ROOF LOADS ADD A POINT LOAD OF 500# @ ANY JOINT WHICH WILL CAUSE MAX STRESS OF TRUSS FH= 41.4K (LRFD) 3x NAILER OFFICE AREA IN ADDITION TO THE ROOF LOADS AND FLOOR LOADS, ADD A POINT LOAD OF 1000# @ ANY JOINT THAT WILL CAUSE MAX STRESS OF TRUSS.
