FEMA P-2091, A Practical Guide to Soil-Structure Interaction (FEMA P-2091)
Date Published: December 20, 2020
FEMA P-2091, A Practical Guide to Soil-Structure Interaction, addresses the impact of soil flexibility on seismic demands, including period lengthening and foundation damping. It provides guidance on modeling soil-structure interaction (SSI) using vertical and horizontal springs, and discusses the effects on acceleration and displacement responses. The guide is designed to help engineers understand and implement SSI in design, with examples and key equations provided.
