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.

Design Notes

  • 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.
