ABSTRACT:
Retrofit connectors that secure together the outside sheathing and underlying structural members of wood-frame or masonry houses, preventing damage when subjected to lateral stresses from a hurricane, or transverse loads from an earthquake. The connectors have special bushings and bearing surfaces that tie the outside sheathing and underlying structural members together, but allow deflection, and transfer of energy to other structural members. Different embodiments of the connectors allow them to adapt to most wood-frame and masonry homes, and to most roof pitches.
