Light-Frame Wood Shear Walls with Various Overturning Restraints

This report addresses several areas of shear wall design with emphasis on the anchorage, overturning restraints, and bottom plate performance. Innovative overturning restraints assembled with metal truss plates were designed and tested to provide an option for accelerated and streamlined on-site assembly of panelized wall systems. The capacity of traditional holddowns in wall assemblies was measured and the failure modes were noted. An analytical methodology for calculating the distribution of uplift forces in conventional shear wall segments, and a design procedure for seismic analysis of shear walls with varying degrees of overturning restraint (including an example for a two-story shear wall) are also presented in this report.
