Floor Panel Bears on Wall – Platform with Fire Retardant-Treated Walls
Floor panel bears on wall below. Wood rim installed on outside face of panel. (FRT may be required by the AHJ; refer to AWC DCA3). Wall above bears on rim and floor panel. A positive connection is made between walls, rim and floor panel with partially-threaded screws.
Purpose: Transfer of vertical load from floor panel and wall above to wall below. Can also transfer in-plane and out-of-plane loads between the wall and floor panel.
- Capacity of primary load path is controlled by perpendicular-to-grain bearing capacity of floor panel or wood stud walls.
- Screws provide load path for in-plane and out-of-plane loads.
- Wood wall studs, plates and sheathing must be fire retardant-treated to receive fire-resistance rating.
- Gravity loads from wall above are transferred through rim to wall below.
- Class 1
- Load Medium
- Cost $$
- Constructability Easy
- Fire Rating II
