Abstract: This report offers a procedure designed for the seismic evaluation of hazardous buildings in the central and eastern United States. The procedure is based upon the methodology of ATC-14, as discussed in this report, which consists of: 1) background material; 2) procedures for determining appropriate seismic loading criteria at a given site; 3) a general evaluation methodology; 4) individual evaluation methodologies for such specific types of buildings as steel-frame buildings, wood frame buildings, unreinforced masonry buildings, etc.; and 5) an evaluation methodology for nonstructural elements. A major portion of the methodology, based upon detailed reviews of building performance data during past earthquakes, concerns the identification of a structure's weak links, those which could precipitate structural or component failure. Ground motion criteria specified in this methodology utilize the effective peak acceleration and velocity maps developed in ATC-3; site-specific ground motion is defined by response spectra corresponding to mean-value spectrum shapes. Generally, the evaluation procedures collect together statements concerning specifically vulnerable areas of a particular structural system, related concerns and analytical techniques applicable to each area.
