Earthquake Strengthening of Cripple Walls in Wood-Frame Dwellings (FEMA P-1024-RA2)

This FEMA Recovery Advisory focuses on strengthening cripple walls in wood-frame dwellings, particularly after the South Napa Earthquake in 2014. It highlights the vulnerability of such structures due to flexible wood foundation walls and inadequate anchorage, offering mitigation measures like plywood bracing and anchor bolts. The advisory includes the FEMA Plan Set for pre-engineered retrofit solutions to enhance the attachment between homes and their foundation systems.
