About this file
This is a VA Handbook on Seismic Design Requirements (H-18-8) establishing mandatory standards for earthquake-resistant construction and retrofitting of Department of Veterans Affairs facilities, effective July 1, 2023, with revisions as of November 1, 2024.
The handbook applies to all VA facilities across the National Cemetery Administration, Veterans Benefits Administration, and Veterans Health Administration. New Critical and Essential Facilities must comply fully with International Building Code (IBC) 2024 earthquake design requirements as modified by this document, while new Ancillary Facilities follow standard IBC requirements without additional modifications. For existing facilities, seismic evaluation and retrofit must comply with ICSSC RP 10-22 standards as modified, with specific triggers requiring evaluation for Critical facilities assigned to Seismic Design Category (SDC) B or higher, Essential facilities at SDC B or higher, and Ancillary facilities at SDC C or higher. Critical Facilities (Risk Category IV) must remain fully functional post-earthquake; Essential Facilities (Risk Category III) must maintain essential functions with minor repairs; and Ancillary Facilities (Risk Category II) are non-essential. Key structural restrictions for high-seismic-design-category facilities prohibit soft-story irregularities, prestressed concrete for seismic resistance, and limit story drift to 50% of ASCE 7 allowances. Nonstructural components and permanent equipment require Special Seismic Certification per ASCE 7 Chapter 13, with Critical facilities requiring a component importance factor of 1.5. Site-specific geologic hazards reports and ground-response reports are mandatory for Critical and Essential facilities in SDCs C-F. The document includes comprehensive facility classifications in Tables 4-8, designating specific VA facility types as Critical, Essential, or Ancillary, with guidance for facilities having varying criticality levels. VA Seismic Safety Coordinator approval is required for alternative structural systems, seismic joints, transfer beams, and other case-by-case design deviations.

Seismic Design Requirements
July 1, 2023 revised November 1, 2024
H-18-8 i
Seismic Design Requirements
FOREWORD
Background
In 1971, after the San Fernando earthquake resulted in the death of 46 patients and staff when two VA buildings collapsed, VA began to undertake a comprehensive seismic safety program. Title 38 - United States Code, Section 8105 requires the Secretary to assure that each medical facility constructed or altered must 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 Department of Veterans Affairs Facilities, which in 1975 formally approved the original VA Seismic Design document, H-08-8, Earthquake Resistant Design Requirements for VA Facilities.
These requirements were developed with the concept that all VA Essential Facilities must remain in operation after an earthquake and were 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 a major rewrite to bring VA seismic design requirements more in line with the updated national model codes. Further updates/revisions of minor nature were made in 1997, 1998, 2000, 2002, 2003, 2005, 2006, 2008, 2010, 2011, 2013, 2016, 2019, 2020, and 2023.
Current Revision Highlights:
Ø The referenced versions of the following codes/standards have been updated to:
IBC 2024, ASCE/SEI 7-22, ASCE/SEI 41-23, AISC 341-22, and RP 10-22.
Ø Renamed Facility Occupancy Category to Facility Criticality Designation.
Ø Sections 2.3 and 4.1 clarify that exempt existing buildings are not exempt from nonstructural requirements of Section 4.0 when permanent components/equipment are added or relocated.
Ø Section 2.4 includes the following revisions for consistency with RP 10-22 triggers for evaluation of existing buildings: replaces the seismicity triggers with equivalent Seismic Design Categories and removes redundant triggers for leased and relocated facilities.
Ø Section 2.7 adds Ancillary facilities for approval of alternative retrofit procedures.
Ø Section 3.2 incorporates recommended changes from the Advisory Committee on Structural
Safety of VA Facilities.
Ø Section 5.1 clarifies field shear wave velocity measurements are used to evaluate the site class.
Ø Updates to Critical, Essential, and Ancillary facilities in Section 7.0, including moving CLCs from
Essential to Critical to be consistent with IBC 2024’s move of Group I-2 Condition 1 buildings (nursing homes) from Risk Category III to Risk Category IV (per IBC Chapter 16 Errata – 11/1/2023).
Ø Miscellaneous errata corrected throughout.
Note: A vertical bar is placed to the right of the revised sections, excluding errata and minor edits.

5.0 SITE DATA FOR NEW AND EXISTING CRITICAL AND ESSENTIAL FACILITIES
Geologic hazards and site-specific ground-response reports shall be required for all proposed construction of new and proposed seismic retrofit of existing Critical and Essential Facilities assigned to SDC C, D, E, or F.
The geotechnical investigation shall use appropriate methods, involving field shear wave velocity measurements, to allow the most accurate evaluation of the site class in accordance with Chapters 20 and 21 of ASCE 7.
5.1 Geologic Hazards Report
The purpose of the geologic hazards report shall be to identify potential geologic and seismic conditions that require detailed evaluation, and may require mitigation by the project. The report shall contain data that provides an assessment of the nature of the site and potential for earthquake damage based on preliminary investigations of the regional and site geology, subsurface conditions and the potential seismic shaking. The engineering geologic report shall not contain design criteria, but shall contain basic data to be used for a preliminary earthquake engineering evaluation of the project. The basis for 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 and local, including estimates of the peak ground accelerations that could occur at the site; and
c. Evaluation of any slope stability problems at or near the site, liquefaction potential and settlement potential of the building site.
VA shall approve the engineering geologic hazard report prior to the preparation of the geotechnical report, which should include the results of quantitative evaluation of the hazards identified in the geologic hazard report.
5.2 Site-Specific Ground-Response Report
The site-specific ground-response report shall present a detailed characterization of earthquake ground motions for the site. The characteristics of the expected strong ground motion to be used in design shall be determined by site evaluation studies based on geological and seismological characteristics of the site, including data given in the engineering geologic hazards report. The estimates should be derived by accepted methods of seismological practice, including the most current Next Generation Attenuation (NGA) relationships where applicable, and fully documented in the ground response report. The level of ground motions to be developed shall be determined using the procedures in Chapter 21 of ASCE 7.
VA shall approve the site-specific ground response report prior to its adoption for project design.
6.0 COMMENTARY
Section 1.0
Section 1.4: After the design level earthquake, all functions in critical buildings and other structures are intended to remain fully functional, whereas in Essential buildings and other structures, all essential functions are intended to remain functional while non-essential functions can be repaired.
Section 2.0
Executive Order 13717 requires Federal agencies comply with the latest edition of the IBC for the seismic design of new Federal buildings and adopt the Standards of Seismic Safety for Existing Federally Owned and Leased Buildings (ICSSC RP Standards) for the minimum seismic safety standards of existing buildings. Both the latest IBC and ICSSC RP Standards must be adopted by Federal agencies within 2 years of issuance. EO 13717 also encourages agencies to exceed both minimum codes and standards to achieve higher resilience in Federal buildings, which is consistent with H-18-8 provisions. The current adopted editions are IBC 2024 and RP 10-22, and the H-18-8 seismic requirements are aligned with the baseline requirements of both IBC 2024 and RP 10-22, with modifications. The modifications are consistent with both ASCE 7 and ASCE 41, which specify procedures for seismic design of new buildings and seismic evaluation and retrofit of existing buildings, respectively.
Section 3.0
Section 3.1: The design engineer shall provide multiple lines of resistance when selecting a lateral force-resisting configuration. Redundancy of frame lines is intended to avoid concentration of seismic force demands in the structure and/or foundation system. Lines of lateral force resistance shall be located at major areas of plan irregularity such as reentrant corners.
Section 3.2: The permitted structural systems listed in Section 3.2 are chosen to provide cost-effective and reliable seismic performance.
Section 3.3c: Because seismic joints have a serious impact on exterior veneer/building envelope, floor joints, and interior construction and utilities, they should be avoided if at all possible.
Section 5.0
Site class is used to determine the values of short-period and 1-second design spectral accelerations, 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 and Chapter 21 of ASCE 7 and is to be presented in the geotechnical evaluation report. Field shear wave velocity measurements typically provide the most reliable basis for an accurate evaluation of site class. Exceptions for low seismicity were removed because certain local site conditions have been observed to significantly amplify response spectral characteristics 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 this provision is to replace those studies (conducted in mid-seventies) for all proposed construction of new and proposed seismic retrofit of existing Critical and Essential Facilities assigned to moderate or high seismic design categories.
New site-specific studies for VA facilities are to consider up-to-date information on the attenuation of earthquake ground motions with distance from the earthquake source, and other relevant seismologic and geologic information. Research sponsored by the Pacific Earthquake Engineering Research Center has led to significantly improved procedures to estimate attenuation of earthquake motions (e.g., publication in 2008 of so-called Next Generation Attenuation (NGA) relationships for plate-boundary tectonic regimes dominated by crustal faults, such as the Western United States). It is the intent of VA requirements that new site-specific studies for VA facilities take advantage of those improved procedures and other pertinent published information on earthquake ground motion estimation, in accordance with the state of practice for the seismic design of buildings.
The standard practice of preparing a geotechnical report containing foundation recommendations, soil-bearing values, results of any necessary soil borings, etc., is still required for all VA projects.
