The Federal Emergency Management Agency (FEMA) has committed under the National Earthquake Hazard Reduction Program (NEHRP) to support implementation of new knowledge and research results for improving seismic design and building practices in the nation. One of the goals of FEMA and NEHRP is to encourage design and building practices that address the earthquake hazard and minimize the resulting risk of damage and injury. The 2015 edition of the NEHRP Recommended Seismic Provisions for New Buildings and Other Structures (FEMA P-1050) affirmed FEMA’s ongoing support to improve the seismic safety of construction in this country. The NEHRP Provisions serves as a key resource for the seismic requirements in the ASCE/SEI 7 Standard Minimum Design Loads for Buildings and Other Structures as well as the national model building codes, the International Building Code (IBC), International Residential Code (IRC) and NFPA 5000 Building Construction Safety Code. FEMA welcomes the opportunity to provide this material and to work with these codes and standards organizations.
FEMA P-1051 provides a series of design examples that will assist the users of the 2015 NEHRP Provisions and the ASCE/SEI 7 standard the Provisions adopted by reference. This product has included several new chapters to provide examples for nonlinear response history analysis procedures, horizontal diaphragm analysis, soil structural interaction, and structures with energy dissipation devices. The eighteen chapters not only illustrate how to apply the new methods and requirements adopted in the 2015 NEHRP Provisions for engineering design, but also cover code conforming updates for the design examples of different structural materials and non-structural components. This product serves as an educational and supporting resource for the 2015 NEHRP Provisions. The new changes in the 2015 NEHRP Provisions have incorporated extensive results and findings from recent research projects, problem-focused studies, and post-earthquake investigation reports conducted by various professional organizations, research institutes, universities, material industries and the NEHRP agencies.
FEMA wishes to express its gratitude to the authors listed in the acknowledgements for their significant efforts in preparing this material and to the BSSC Board of Direction and staff who made this possible. Their hard work has resulted in a resource product that will provide important assistance to a significant number of users of the 2015 NEHRP Provisions, and the upcoming new edition of national design standards and model building codes with incorporated changes based-on the Provisions.
