ATC-110 (CEA 2)
Project Title: Development of a Prestandard for the Evaluation and Retrofit of One and Two Family Light Frame Residential Buildings
Client: California Earthquake Authority; Federal Emergency Management Agency
Purpose: This project developed a prestandard for vulnerability-based seismic assessment and retrofit of one- and two-family wood light frame residential buildings. The prestandard is supported by prescriptive, pre-engineered set of plans that can be adapted to retrofit crawlspace dwelling cripple walls, living-space-over-garage dwelling ground story bracing walls, masonry chimneys and masonry fireplace surrounds in wood light-frame dwellings, as well as the technical basis of the prestandard. ATC is currently developing a training course in accordance with the prestandard.
