FEMA P-1100, Vulnerability-Based Seismic Assessment and Retrofit of One- and Two- Family Dwellings

improved seismic design and seismic retrofitting of vulnerable configurations will increase the probability that homes are available to provide shelter immediately following moderate to large seismic events. The purpose of this prestandard is to provide a methodology to identify and retrofit specific known vulnerabilities in wood light-frame dwellings. Development of the assessment and retrofit provisions has included using the best available seismic numerical modeling tools and engineering practices to assist in developing assessment methods and identifying retrofit criteria to best achieve targeted performance objectives. The use of the provisions is anticipated to improve earthquake performance but is not intended to prevent earthquake damage.

FEMA P-1091, Recommended Simplified Provisions for Seismic Design Category B Buildings (2017)

Simplification of seismic design provisions for buildings is desirable for anyone who uses the seismic provisions of the building code, including structural engineers and local building officials. This goal has been explored in various ways over decades through efforts supported by the Federal Emergency Management Agency (FEMA) as part of its responsibilities under the National Earthquake Hazards Reduction Program (NEHRP) through the FEMA-funded NEHRP Provisions Update Committee as well as through other code development organizations such as the American Society of Civil Engineers/Structural Engineering Institute (ASCE/SEI) 7 Seismic Subcommittee, as summarized in the Appendix of this document.

National Earthquake Hazard Reduction Program (NEHRP) Overview

Established by Congress in 1977, the National Earthquake Hazard Reduction Program (NEHRP) works to reduce risks to life and property resulting from earthquakes. Focusing on research, building code standards, technical guidance, and education, NEHRP is a collaborative effort among the Federal Emergency Management Agency (FEMA), the National Institute of Standards and Technology (NIST), the National Science Foundation (NSF), and the United States Geological Survey (USGS).

Seismic Design of Rigid Wall-Flexible Diaphragm Buildings: An Alternate Procedure (FEMA P-1026)

This FEMA NEHRP document is a new design resource that applies recent research and testing results to address the seismic performance issue of “big box” buildings. This type of buildings is typically used for warehouses or retail stores and has been reported for numerous earthquake damage or collapses in the past.

Earthquake Strengthening of Cripple Walls in Wood-Frame Dwellings (FEMA P-1024-RA2)

On August 24, 2014, a magnitude-6.0 earthquake occurred in Napa, California. In response to this earthquake, the Special Projects task of the National Earthquake Technical Assistance Program (NETAP) was used to fund an investigation. At the time, this event had not yet been declared a federal disaster, and disaster funds were therefore not available. Because of limitations to this funding, some issues, such as performance of lifelines or building investigations in additional areas, could not be investigated. Past earthquakes in California have resulted in significant improvements to national and local building codes. For the 2014 South Napa earthquake, work was focused on documenting the observed performance of buildings and nonstructural components in order to lead into future improvements in future building codes, and to do so within six months.

Recovery Advisory 2 (RA2) is Appendix B of the FEMA P-1024 report. RA2 addresses measures to mitigate cripple wall vulnerabilities before an earthquake occurs and provides information on how and when to use the accompanying FEMA Plan Set.

Tribal Mitigation Planning and HMA Grant Application Development

This job aid provides considerations for developing a mitigation planning grant scope of work. It will help users understand what is needed for a hazard mitigation plan and the level of effort and cost implications of those needs. This job aid can be used by both tribal applicants and subapplicants.
