FEMA P-2091, Webinar on A Practical Guide to Soil-Structure Interaction

Purpose. Drawing from the FEMA P-2091 report, A Practical Guide to Soil-Structure Interaction, this webinar will assist engineers in determining when soil-structure interaction SSI effects are of importance and how to implement them in design.
Background. Modern building codes include criteria for how ground motions enter a structure’s foundation and affect the building response. This soil-structure interaction (SSI) can make a substantial difference in how buildings behave during earthquake shaking and how they should be designed, yet there is relatively little implementation of SSI effects by practicing structural engineers. Provisions are available in ASCE/SEI 7-16 and in ASCE/SEI 41-17 that can be used to address SSI, but they can be hard to follow, and limited guidance is available.
To help guide engineers, the Applied Technology Council (ATC), with funding from the Federal Emergency Management Agency (FEMA), published FEMA P-2091, A Practical Guide to Soil-Structure Interaction. The overall goal of this Guide is to present information regarding SSI as implemented in code provisions but in an easy-to-understand, concise format targeted towards practicing engineers to help them determine when SSI effects are of importance and show them examples of how to implement them in design.
