This special edition has been developed to meet the specific requirements of the California Office of Statewide Health Planning and Development (OSHPD) for hospital and health care facilities construction. The seismic hazard tables with this special edition are limited to the SHL A (g = 0.67) and SHL AA (g = 1.0) applicable to the hospital and health care facilities outlined in the use of the manual. The manual is not intended to cover the ordinary supports for ducts and pipes required for gravity loads. The only restraints shown in the tables and figures are those needed to provide the extra support for seismic loads.
