Cripple Walls in Wood-Frame Dwellings


Thursday, May 26, 2016
12:00 – 1:30 pm Pacific
Registration Fee: Free 
1,000 registrations (sites) maximum

 Purpose. This webinar will provide an overview of the FEMA P-1024/RA2 document, Earthquake Strengthening of Cripple Walls in Wood-Frame Dwellings, developed by the Applied Technology Council (ATC) for the Federal Emergency Management Agency (FEMA) in response to the 2014 South Napa Earthquake.  This month, the document was recognized with the 2016 Excellence in Engineering Award of Merit in the category of Study/Research/Guidelines by the Structural Engineering Association of Northern California (SEAONC). 

This document addresses the earthquake strengthening of cripple walls and foundation anchorage in one- and two-family dwellings, supported by elevated concrete foundation systems and cripple walls not taller than approximately seven feet.  The FEMA Plan Set for Earthquake Strengthening of Cripple Walls in Wood-Frame Dwellings accompanying this Recovery Advisory is intended to be used as a template for strengthening common cripple wall and foundation anchorage vulnerabilities in California and throughout the United States.  It provides pre-engineered strengthening solutions with step-by-step instructions for use by a knowledgeable and skilled contractor or homeowner.

Intended Audience. This webinar has been designed for engineers, architects, building officials, and others who are interested in earthquake strengthening of cripple walls.

Handouts.  All registrants will receive access to PDF electronic copy of FEMA P-1024/RA2, as well as the accompanying documents, FEMA P-1024, Performance of Buildings and Nonstructural Components in the 2014 South Napa Earthquake, and FEMA P-1024/RA1,  South Napa Earthquake Recovery Advisory:Repair of Earthquake-Damaged Masonry Fireplace ChimneysWebinar handouts may also be ordered by contacting the FEMA Publications Warehouse, by e-mail: This email address is being protected from spambots.
