ABSTRACT:
A system for modifying existing wood frame buildings to protect them from damage due to seismic and wind forces. At least one (preferably several) deadman is formed adjacent to a peripheral foundation that supports rim joists on foundation sill plates at the foundation and plural crossed beams and floor framing joists. The deadman preferably comprises concrete. A plurality of transfer blocks and compression blocks are fastened along said rim joists between at least some of the framing joists. Elongated transfer ties are secured to the transfer blocks and pass adjacent to the deadman. At least one anchor embedded in the deadman and is fastened to the transfer tie. At least one additional anchor may be secured to the deadman and fastened to an adjacent framing joist. Framing joists preferably have short tie straps overlapping all joist connections and fastened to the joists. Exterior wall covering material may be removed adjacent to the foundation sill plate and any wall sill plates. Elongated tie straps are then fastened along those plates. Anchor means may be fastened to those tie straps and be embedded in the deadmen. The deadmen are preferably cast in place with the anchors partially embedded in the deadman during casting.
