Purpose. Drawing from FEMA P-2006 material, this webinar will provide an introduction to ASCE/SEI 41, including a discussion of its foundational principles, performance objectives, analysis procedures, and acceptance criteria.

Background. Since its original publication in 2006, ASCE/SEI 41, Seismic Evaluation and Retrofit of Existing Buildings, has become the consensus U.S. national standard for seismic evaluation and retrofitting. However, the methods in ASCE/SEI 41 are different in many ways from those used in the design of new buildings and can be challenging for those unfamiliar with its procedures. To assist users of the standard, the Applied Technology Council, with funding provided by the Federal Emergency Management Agency (FEMA) and with assistance from the Structural Engineers Association of California (SEAOC), published an example application guide for ASCE/SEI 41, referred to as the FEMA P-2006 document. FEMA P-2006 provides helpful guidance on the interpretation and the use of ASCE/SEI 41 through a set of step-by-step illustrated design examples that cover key selected topics.

Intended Audience. The intended audience for this webinar is both practicing engineers who have limited or no experience with ASCE/SEI 41 and those engineers who have used the standard but would like a refresher on the procedures. This webinar is also intended for building officials, architects, and others who interact with the ASCE/SEI 41 standard.
