NEHRP Recommended Seismic Provisions 1985-2015
The National Earthquake Hazards Reduction Program (NEHRP) Recommended Seismic Provisions for New Buildings and Other Structures is a series of publications developed by the BSSC and published by FEMA. The first edition was published in 1985, with later editions in 1988, 1991, 1994, 1997, 2000, 2003, 2009 and 2015. The 2020 editions is scheduled to be published in September/October 2020.

NEHRP Future Provisions and Research Needs — Request for Input (April 2020)
As part of its efforts to regularly update the NEHRP Recommended Seismic Provisions for New Buildings and Other Structures, the Building Seismic Safety Council (BSSC) is charged by the Federal Emergency Management Agency (FEMA) to identify and recommend issues to be addressed and research needed to advance the state of the art of earthquake-resistant design and to serve as the basis for future refinement of the Provisions. During the project to generate the 2020 edition of the Provisions, the various Issue Teams and Study Groups that assisted with the development of proposals for the Provisions Update Committee (PUC) and Member Organization ballots identified specific items that were beyond the scope of the 2020 Provisions update. These were assembled and edited by an Oversight Committee led by PUC members Kelly Cobeen and S.K. Ghosh. Download the report.
BSSC is seeking input and in particular, BSSC asks for response to the following questions:

BSSC 2020 NEHRP Provisions Resource Paper: Resilience—Based Design and the NEHRP Provisions (February 2020)
A Part III Resource Paper approved for the 2020 NEHRP Recommended Seismic Provisions for New Building and Other Structures addresses the potential relationship between future NEHRP Provisions and resilience–based earthquake design, especially in the context of definitions and priorities established in federal law by the 2018 NEHRP reauthorization. Keywords: Resilience, Functional Recovery, NEHRP Provisions, Seismic Design. Download the report.
BSSC Project 17 Final Report Development of the Next Generation of Seismic Design Value Maps for the 2020 NEHRP Provisions (December 2019)
Federal Emergency Management Agency (FEMA), Building Seismic Safety Council (BSSC) and U.S. Geological Survey (USGS) act cooperatively to develop the seismic design value maps. The current maps have undergone an evolutionary process over the past 30 years, with major innovations introduced approximately once every 10 years through efforts known as Project 97, Project 07, and Project 17. This Project 17 report documents the activities and recommendations to develop a consensus basis for next-generation seismic design value maps and/or tools for adoption by the 2020 NEHRP Recommended Provisions for New Buildings and Other Structures (NEHRP Provisions). These recommendations were prepared by a joint committee of volunteer engineers empaneled by the BSSC and USGS engineers and scientists and funded by FEMA. Download the report.
FEMA/BSSC 2020 NEHRP Provisions Session at 2019 SEAOC Convention Conference Papers (August 2019)
Building Seismic Safety Council (BSSC) organized a session at the 2019 SEAOC Convention. The BSSC PUC members presented some of the important code change proposals that will be included in the 2020 NEHRP Recommended Seismic Provisions for New Buildings and Other Structures.
Project 17 Workshop on Seismic Hazard Mapping Proceedings (April 2017)
On November 28, 2016, a Project 17 Workshop on Seismic Hazard Mapping was organized and presented by the Project 17 Committee of BSSC. The workshop was sponsored by the Federal Emergency Management Agency (FEMA)'s National Earthquake Hazards Reduction Program (NEHRP) in coordination with the US Geological Survey (USGS). The purpose of the workshop was to critic on some options to solve critical issues related to seismic design value maps, and seek input on important issues related to development of the next generation of seismic design value maps from structural engineers, building officials, and members of the earthquake community. These proceedings include the Project 17 Workshop participants list by discussion group, a recording of the discussion groups’ straw votes, workshop announcement, technical background paper, and presentations. download the Proceedings
Development of the 2020 NEHRP Provisions — ASCE/SEI 7–16 Adoption Report (November 2017)
This report, prepared at the outset of the 2020 NEHRP Provisions development cycle, presents some important background on the NEHRP Provisions development process and summarizes the results of the first ballot in the 2020 development cycle to adopt ASCE/SEI 7–16 as the primary reference document for the Provisions. As a practice initiated with the 2009 edition of the Provisions, after adopting ASCE/SEI 7, the BSSC makes substantive recommendations for modification and improvement to the standard based on recent research and improvements in knowledge. In the 2015 NEHRP Provisions the BSSC developed significant modifications to ASCE/SEI 7–10, which were then adopted in ASCE/SEI 7–16. For the 2020 Provisions the BSSC has adopted ASCE/SEI 7–16 as the reference with the intent to make changes that will be reflected in ASCE/SEI 7–22. This report also summarizes some of the important changes made by the 2015 NEHRP Provisions that were adopted by ASCE/SEI 7–16 and a few changes that were further modified in the ASCE/SEI 7–16.

2015 NEHRP Provisions
The following publications were prepared for the U. S. Department of Homeland Security, Federal Emergency Management Agency by the National Institute of Building Sciences Building Seismic Safety Council. All FEMA publications can also be ordered by calling FEMA Publications (800-480-2520). The publications are available as Adobe Acrobat PDFs unless otherwise noted.
NEHRP Recommended Seismic Provisions for New Buildings and Other Structures
The 2015 NEHRP Provisions was used as the primary resource for the professional design standard ASCE/SEI 7-16 Minimum Design Loads for Buildings and Other Structures referenced in the International Building Code (IBC).
Training and Education Materials
The BSSC develops educational, training materials and explanatory information to support the customers of the NEHRP Provisions. The Provisions provide in-depth and complete commentary on the seismic design requirements in the ASCE 7. The NEHRP Recommended Seismic Provisions: Design Examples, FEMA P-1051, based on the Provisions, are intended for those who are experienced structural designers, but are relatively new to the field of seismic design. The design examples explain the principles behind the Provisions and include types of structures, materials, and specific seismic load resisting elements that illustrate to the reader how to apply the new requirements and to handle critical issues when conducting seismic design of the specific structural system. Practitioners and academics also will find useful training and educational slides in FEMA P-1052. Seminars and workshops are intended be held based on the FEMA P-1052 materials.

NEHRP Recommended Seismic Provisions: Design Examples
The NEHRP Recommended Provisions: Design Examples are written to illustrate and explain the applications of the 2015 NEHRP Recommended Seismic Provisions for Buildings and Other Structures, ASCE 7-16 Minimum Design Loads for Buildings and Other Structures and the material design standards referenced therein and to provide explanations to help understand them.
NEHRP Recommended Seismic Provisions: Training Materials
FEMA P-1052, 2015 NEHRP Recommended Seismic Provisions: Training and Instructional Materials, as one of the NEHRP Provisions’ supporting products, contains a set of slides for use with FEMA P-1051, 2015 NEHRP Recommended Seismic Provisions: Design Examples. The training materials are developed in 18 chapters to provide background and complementary information for the corresponding design examples chapters.

Simplified Seismic Design Procedures Development Program
In response to the demands from building officials and building designers for quick and simplified seismic design procedures, the BSSC addressed developing easily accessible simplified seismic design procedures. The objective of simplified design is to help structural engineers to quickly produce designs of targeted structural systems with equivalent or above code required seismic performance.
