This report was developed with funding from the USGS, the Southern California Earthquake Center (SCEC), OES, and the Institute for Business and Home Safety (IBHS). (Published 2001, 260 pages, with CD-ROM containing complete database)

ABSTRACT: The report documents the earthquake performance of 530 buildings within 1000 feet of sites where strong ground motion was recorded during the 1994 Northridge, California, earthquake (31 recording sites in total). The project required the development of a suitable survey form, the training of licensed engineers for the survey, the selection of the surveyed areas, and the entry of the survey data into an electronic relational database. The full database is contained in the ATC-38 CD-ROM. The ATC-38 database includes information on the structure size, age and location, the structural framing system (in terms of 14 standardized model building types) and other important structural characteristics, nonstructural characteristics, geotechnical effects, such as liquefaction, performance characteristics, such as the degree of damage, if any, to the structural system, nonstructural elements, equipment and contents, fatalities and injuries, and estimated time to restore the facility to its pre-earthquake usability. The report and CD also contain strong-motion data, including acceleration, velocity, and displacement time histories, and acceleration response spectra. Also included in the report and the database are results from a separate survey, on repair costs and time out of service (loss-of-function data), mailed to owners of damaged commercial buildings.
