CUREE-Caltech Woodframe Project

The CUREE-Caltech Woodframe Project consisted of coordinated engineering investigations and implementation activities whose objective was to significantly reduce earthquake losses to woodframe construction. The project was funded by the Federal Emergency Management Agency (FEMA) through a grant administered by the California Governors Office of Emergency Services.
