VA Handbook 18-8Seismic Design RequirementsFOREWORDNovember 1, 2019Revised May 1, 2020BackgroundIn 1971, after the San Fernando earthquake resulted in the death of 46 patients and staff whentwo VA buildings collapsed, VA began to undertake a full seismic safety program. Title 38 - UnitedStates Code, section 8105 required the Secretary to assure that each medical facility constructedor altered shall be of construction that is resistant to fire, earthquake, and other natural disasters.This initiated the creation of the Secretary’s Advisory Committee on Structural Safety of VAFacilities, which formally approved in 1975 the original VA Seismic Design document, H-08-8,Earthquake Resistant Design Requirements for VA Facilities. These requirements were developedwith the concept that all VA Essential Facilities must remain in operation after an earthquake andwere far in advance of National Codes.This document is periodically updated and revised. The revision of H-08-8 to H-18-8 in 1995 was amajor rewrite to bring VA seismic design requirements more in line with the updated nationalmodel codes. Further updates/revisions of minor nature were made in 1997, 1998, 2000, 2002,2003, 2005, 2006, 2008, 2010, 2011, 2013, and 2016.Current Revision Highlights: Referenced versions of national codes and standards updated to the latest date-specific editionsat the time this standard was published. Definitions of Critical, Essential, and Ancillary facilities have been clarified in Sections 1.4 and 7.0. Section 2.5 corrects an error in the October 1, 2016 edition of H-18-8 that inadvertently excludedAncillary facilities from the requirement to use nonlinear procedures for retrofit. Outdated exemptions for existing structures and nonstructural components and equipment wereremoved and the Importance Factor, Ip, for all nonstructural components is set to 1.5 for Criticalfacilities in Seismic Design Categories C, D, E, and F, consistent with California’s Office of StatewideHealth Planning & Development (OSHPD) provisions. In Section 4.2, reference to an outdated OSHPD Code Application Notice (CAN) regarding ruggedequipment was replaced with lists of typical equipment requiring Special Seismic Certification andrugged equipment exempt from certification.Note: A vertical bar is placed to the right of the revised sections.John G.

VA Handbook 18-8Seismic Design Requirements5.0 SITE DATA FOR CRITICAL AND ESSENTIAL FACILITIESNovember 1, 2019Revised May 1, 20205.1 New and Existing FacilitiesGeologic hazards and site-specific ground-response reports shall be required for allproposed construction of new and proposed seismic retrofit of existing Critical andEssential Facilities assigned to Seismic Design Category C, D, E, or F.The geotechnical investigation shall use appropriate methods to allow the most accurateevaluation of the site class in accordance with Chapters 20 and 21 of ASCE 7, includingfield shear wave velocity measurements.5.2 Geologic Hazards ReportThe purpose of the geologic hazards report shall be to identify potential geologic andseismic conditions that require detailed evaluation, and may require mitigation by theproject. The report shall contain data that provides an assessment of the nature of thesite and potential for earthquake damage based on preliminary investigations of theregional and site geology, subsurface conditions and the potential seismic shaking. Theengineering geologic report shall not contain design criteria, but shall contain basic datato be used for a preliminary earthquake engineering evaluation of the project. The basisfor seismic assessment in geologic hazards reports must be stated clearly.The report shall include, but shall not be limited to the following:a.Geologic investigation;b.Identification of any known active and potentially active faults, both regional andlocal, including estimates of the peak ground accelerations that could occur at thesite; andc.Evaluation of any slope stability problems at or near the site, liquefaction potentialand settlement potential of the building site.VA shall approve the engineering geologic hazard report prior to the preparation of thegeotechnical report.5.3 Site-Specific Ground-Response ReportThe site-specific ground-response report shall present a detailed characterization ofearthquake ground motions for the site. The characteristics of the expected strong groundmotion to be used in design shall be determined by site evaluation studies based ongeological and seismological characteristics of the site, including data given in theengineering geologic hazards report. The estimates should be derived by acceptedmethods of seismological practice, including Next Generation Attenuation (NGA)12

VA Handbook 18-8Seismic Design RequirementsNovember 1, 2019Revised May 1, 2020relationships where applicable, and fully documented in the ground response report. Thelevel of ground motions to be developed shall be determined using the procedures inChapter 21 of ASCE 7.VA shall approve the site-specific ground response report prior to its adoption for projectdesign.13

VA Handbook 18-8Seismic Design Requirements6.0COMMENTARYNovember 1, 2019Revised May 1, 2020Section 1.0Section 1.4: After the design level earthquake, all functions in critical buildings and otherstructures are intended to remain fully functional, whereas in Essential buildings andother structures, all essential functions are intended to remain functional while nonessential functions can be repaired.Section 2.0Sections 2.3-2.6: Executive Order 13717 requires Federal agencies adopt RP 8 and futureeditions for the minimum seismic safety standards of existing buildings and encouragesagencies to exceed the minimum standards of RP 8 to achieve more resilience in Federalbuildings. The H-18-8 seismic evaluation and retrofit requirements for existing buildingsare aligned with the baseline requirements of RP 8, with modifications. The modificationsare consistent with ASCE 41-17, which specifies procedures for evaluation and retrofit ofexisting buildings.Section 3.0Section 3.1: The design engineer shall provide multiple lines of resistance when selectinga lateral force-resisting configuration. Redundancy of frame lines is intended to avoidconcentration of seismic force demands in the structure and/or foundation system. Linesof lateral force resistance shall be located at major areas of plan irregularity such asreentrant corners.Section 3.2: The permitted structural systems listed in Section 3.2 are chosen to providecost-effective and reliable seismic performance.Section 3.3c: Because seismic joints have a serious impact on exterior veneer/buildingenvelope, floor joints, and interior construction and utilities, they should be avoided if atall possible.14

VA Handbook 18-8Seismic Design RequirementsSection 5.0November 1, 2019Revised May 1, 2020Site class is used to determine the values of short-period and 1-second design spectralaccelerations, SDS and SD1 that define Seismic Design Category in accordance with ASCE 7.An accurate evaluation of site class is to be made in accordance with Chapter 20 andChapter 21 of ASCE 7 and is to be presented in the geotechnical evaluation report. Fieldshear wave velocity measurements typically provide the most reliable basis for anaccurate evaluation of site class. Exceptions for low seismicity were removed becausecertain local site conditions have been observed to significantly amplify response spectralcharacteristics within a period range which may be in resonance with certain structures.Although geotechnical studies exist for most of VA’s vulnerable sites, the intent of thisprovision is to replace those studies (conducted in mid-seventies) for all proposedconstruction of new and proposed seismic retrofit of existing Critical and EssentialFacilities assigned to moderate or high seismic design categories.New site-specific studies for VA facilities are to consider up-to-date information on theattenuation of earthquake ground motions with distance from the earthquake source, andother relevant seismologic and geologic information. Research sponsored by the PacificEarthquake Engineering Research Center has led to significantly improved procedures toestimate attenuation of earthquake motions (e.g., publication in 2008 of so-called NextGeneration Attenuation (NGA) relationships for plate-boundary tectonic regimesdominated by crustal faults, such as the Western United States). It is the intent of VArequirements that new site-specific studies for VA facilities take advantage of thoseimproved procedures and other pertinent published information on earthquake groundmotion estimation, in accordance with the state of practice for the seismic design ofbuildings.The standard practice of preparing a geotechnical report containing foundationrecommendations, soil-bearing values, results of any necessary soil borings, etc., is stillrequired for all VA projects.15
