This structural detail outlines specific design and loading criteria for steel or wood roof joists and trusses. The top chord features a three-inch nailer and requires checking for top chord bending of 250 pounds and bottom chord bending of 200 pounds, noted as non-additive loads. In the warehouse area, a concentrated point load of 500 pounds must be added at any joint producing maximum truss stress, alongside a horizontal force of 27.5 kips (LRFD) unless noted otherwise on plan. In the office area, an additional point load of 1000 pounds is required at any joint causing maximum stress under combined roof and floor loads. Joist dimensions and specific configurations are deferred to the manufacturer's shop drawings.
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= 27.5K (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. UNO ON PLAN
