This volume of design examples is intended for those experienced structural designers, who are relatively new to the field of earthquake-resistant design and to the 2015 NEHRP Provisions. By extension, it also applies to use of the current model codes and standards because the Provisions is the key resource for updating seismic design requirements in most of those documents including ASCE 7 Standard, Minimum Design Loads for Buildings and Other Structures; and the International Building Code (IBC). Furthermore, the 2015 NEHRP Provisions (FEMA P-1050) adopted ASCE7-10 by reference, and the 2012 International Building Code adopted ASCE7-10 by reference; therefore, seismic design requirements are essentially equivalent across the Provisions, ASCE7 and the national model code. The Provisions and the national model codes and standards attest to the success of FEMA and NEHRP and BSSC efforts to ensure that the nation’s building codes and standards reflect the state-of-the art of earthquake-resistant design.
This edition of the design examples reflects the technical changes in the 2015 NEHRP Provisions just as the previous version, the FEMA P-751 Design Examples published in September 2012, reflected the 2009 NEHRP Provisions. Updated education/training materials to supplement this set of design examples will be published as a separate FEMA product, 2015 NEHRP Recommended Seismic Provisions: Training Material, FEMA P-1052.
