ABSTRACT:
A novel prefabricated shearwall is disclosed with improved structural characteristics in terms of its ability to 1) transfer lateral loads to the foundation, 2) resist bending moments normally arising in conventional shearwalls between hold-down hardware and end posts or vertical framing members, 3) effectively diffuse stresses known to result in nail fatigue, and 4) reduce slippage between the bottom of the end posts and base in response to cyclic loadings. These superior properties result partly from its geometry in lower, or shear force transfer region, accompanied by thrust block/anchor rod assemblies to provide stiffness and strength over the lower portion of the end posts. Furthermore, specialized wrap-around connector plates that cover a portion of the bottom surface of these end posts also contribute to the enhanced prefabricated shearwall design.
