The following documents provide information concerning the earthquake-resistant provisions of the most recent editions of the This document provides a readily understandable explanation of the intent and requirements of the seismic related building codes and standards that are based on the National Earthquake Hazards Reduction Program (NEHRP) The CodeMaster products provide designers with an easy-to-use desk reference that identifies the seismic provisions in the International Building Code as well as the seismic requirements of ASCE/SEI 7. The project team concluded that the findings are reliable only when viewed from an aggregate point of view.Phase 2 widened the scope of the flood pilot study to focus on all eight states in FEMA Region IV.The hazard-specific modeled building code provisions that contributed to the losses avoided were:Phase 2 identified that hundreds of millions of dollars in losses avoided resulted from the current I-Code use over the past 14 years in this part of the country covered by FEMA Region 4. The strategy’s focus on codes as a keystone mitigation investment strategy aligns with FEMA’s current strategic plan, and highlights that up-to-date building codes help communities survive, remain resilient, and continue to provide essential services after a disaster occurs. Subjects addressed include determination of mapped spectral response accelerations; consideration of exceptions to the seismic code requirements; Seismic Design Category determination; consideration of plan and vertical structural irregularities; determination of seismic base shear, redundancy coefficient and seismic load effects; and compliance with drift control requirements. The findings are intended to inform and aid proactive risk-reduction planning and decision-making by community officials.The pilot study presented the quantitative estimates of losses avoided for the seismic hazard in Salt Lake County, UT, and for both the hurricane and flood hazards in Charleston County, SC. Culminating over a decade of research, the Study quantifies the associated physical and economic losses from flooding, hurricane wind, and earthquakes that were avoided due to buildings being constructed according to modern, hazard-resistant building codes and standards. It includes a wide variety of techniques that have been developed and used for repair and retrofitting of earthquake-damaged and seismically deficient buildings.This guide describes the sources of nonstructural earthquake damage and effective methods of reducing potential risks associated with such damage.
Comparing and scaling losses avoided study findings is intended to help accelerate the dialogue and shape perceptions towards a goal of full nationwide code adoption. Continual increase to the nation’s losses avoided through disaster-resistant building codes will improve resilience to natural disasters. The seismic pilot study in Salt Lake County, Utah, used a combination of county assessor’s data and the results of a previous Hazus development effort conducted as part of the 2010 Utah ShakeOut scenario and exercise. Federal government websites often end in .gov or .mil. The resulting quantifiable benefits could then be incorporated across technical guidance and mitigation strategies and impact many communities and stakeholders.The ability to develop a common framework for a nationwide losses avoided study is made possible by the I-Codes. FEMA is studying how updated building codes, such as using concrete for increased resiliency, could reduce the amount of damage during natural disasters. These guides can be purchased from The Structural Engineers Association of California has partnered with International Code Council to update its series of Structural/Seismic Design Manuals to the 2015 International Building Code. Specifically, Florida was the dominant state with the greatest exposure and the most avoided losses.Phase 3’s purpose was to formalize a methodology that is being implemented in the Phase 4 nationwide study.
Higher building code standards are a sorely needed new normal for accelerating hazard reduction and avoided losses.
Also included are discussions of masonry and stone elements, examples of typical floor plans for earthquake- resistant one- and two-story homes, excerpts of seismic requirements from building codes, and checklists for homebuilders.This publication documents common seismic rehabilitation or retrofitting techniques used for buildings represented in the set of standard building types presented in seismic publications.
FEMA has produced many publications for a variety of audiences to identify and correct building vulnerabilities through seismic rehabilitation. As more buildings are constructed in compliance with disaster-resistant codes that accrue over time, the avoided losses will increase.Energy codes are not part of the study.
As a reference, the hazard specific slides in the August 2019 FEMA The Hazus team has a release schedule for product updates. The study does not address life cycle costs. To measure the benefits, FEMA developed, tested, and validated a method using a progressive phased approach. An official website of the United States government In addition, five occupancy types (three commercial, two residential) are included to represent the largest percentage of recently constructed buildings in Salt Lake County.The flood pilot study conducted in Charleston, South Carolina, included data from five incorporated towns and cities.
