Building Seismic Safety Council 2015 Colloquium

2015 BSSC Colloquium Presentations

The National Institute of Building Sciences Building Seismic Safety Council (BSSC) presented the BSSC Colloquium to describe key outcomes, major updates, and future research needs from the National Earthquake Hazards Reduction Program (NEHRP) 2015 Provisions update process. Titled “Seismic Design Technology for New Buildings — the 2015 NEHRP Recommended Seismic Provisions for New Buildings and Other Structures (FEMA P-1050),” the event was held February 11, 2015, in Burlingame, California. A total of 90 attendees registered to participate, including professionals from the structural engineering community and members of the BSSC.


Under the sponsorship of the Federal Emergency Management Agency (FEMA), BSSC administers an ongoing consensus-based process of updating and maintaining the NEHRP Recommended Provisions for New Buildings and Other Structures. The NEHRP Recommended Provisions and its Commentary embody the state-of-knowledge criteria for design and construction of new buildings subject to earthquake hazards. The new knowledge and technologies contained in this resource document are diffused into the model building codes developed by the International Code Council (ICC) and several national standards, including the American Society of Civil Engineers (ASCE) Structural Engineering Institute (SEI) ASCE/SEI-7 Minimum Design Loads for Buildings and Other Structures.


The BSSC Colloquium program included 15 presentations on the development of the Provisions; major changes from the previous edition of the Provisions; and key topics that explain new technologies, why changes occurred, how they will affect structures to be built and future research issues.
