Introduction to 2024 Edition of the IRC/IBC Seismic Design Category Maps and FEMA’s Building Code Strategy Implementation to Advance National Building Code Adoption

Jul 11, 2024   |   1:00 PM – 2:00 PM ET
Virtual Event

Join us for an inside look into the 2024 editions of the Seismic Design Category (SDC) Maps for the International Residential Code (IRC) and International Building Code (IBC). The SDC maps were developed under FEMA's responsibilities within the National Earthquake Hazards Reduction Program (NEHRP) and have been adopted by the 2024 IRC and IBC. This webinar is one of FEMA NEHRP's outreach activities to keep at-risk communities and relevant professionals informed about the latest seismic hazard information for building design and construction. As one of the four NEHRP agencies, FEMA NEHRP's responsibilities include helping translate and implement research results and lessons learned from recent earthquakes into practical guidance through publications, tools, trainings and building code work to improve the Nation’s earthquake resilience.

Seismic design maps illustrate the varying earthquake demands considered in the design of buildings and other structures across the U.S. and territories. These maps also provide general earthquake hazard information and informing earthquake risk reduction projects.

The concept of the SDC integrates several key factors that influence seismic performance of structures, including potential earthquake ground motions, site soil amplification of ground motions, structure size and configuration, and structure occupancy and use.

This webinar also will feature an introduction to FEMA’s Building Code Strategy program, advancing the adoption and enforcement of hazard-resistant building codes and standards for FEMA programs. The program’s goals and objectives focus on leveraging partnerships to promote current hazard-resistant building codes and understanding stakeholder needs to identify opportunities that advance building code adoption and enforcement.
