Simpson Strong-Tie Seismic Retrofit Guide
This 20-page document contains general guidelines that are intended to improve the seismic performance of wood-frame homes in the U.S., but will not necessarily prevent earthquake damage. The guidelines apply to homes with crawl spaces and cripple walls. They address reinforcing the cripple wall, but not the walls above. The information in the guide is intended to show how Simpson Strong-Tie products should be installed. 1.4 MB
