Database Information

ATC-13-D. The ATC-13 Diskette contains two sets of electronic data from the ATC-13 report, Earthquake Damage Evaluation Data for California, which was published by the Applied Technology Council in 1985. The first data set consists of expert-opinion damage probability matrices for 78 classes of California industrial, commercial, residential, utility and transportation structures, defined in terms of their general earthquake-resistance characteristics. Each damage probability matrix provides the probability that damage, expressed as repair cost divided by replacement value, will be in a specified range, given the severity of ground shaking, expressed in terms of Modified Mercalli Intensity. The second data set provides expert-opinion estimates of time to restore damaged facilities to pre-earthquake usability for 35 classes of industrial, commercial, residential, agricultural, government, education, utility, transportation and flood control structures, defined in terms of their social function. Times to restore each facility to 30%, 60% and 100% of pre-earthquake usability are provided for each facility type. The data are available on one 3½" diskette in PC-compatible format.

ATC-25-D. The ATC-25 Diskettes contains an electronic inventory of lifeline transmission facilities for the conterminous United States. The data were used in the development of the ATC-25 report, Seismic Vulnerability and Impact of Disruption of Lifelines in the Conterminous United States, which was published by the Applied Technology Council in 1991. With the exception of oil and gas pipeline data provided by the National Petroleum Council, the inventory of data generally were provided by the Federal Emergency Management Agency (FEMA) and date from about 1966, unless later updated by FEMA. The specific lifelines included in the ATC-25 database inventory are: transportation (highways, railroads, airports, ports and harbors); energy (electric power transmission, gas and liquid fuel transmission pipelines); emergency service facilities (emergency broadcast facilities and hospitals); and water aqueducts and supply. Each of the lifelines has been inventoried in terms of its nods and links. The data were combined and reduced through two operations: (1) reduction in the number of links by a factor of about ten to reduce the size of the database to a manageable size for analysis (i.e., minor curvatures at the local level have been eliminated); and (2) continuity corrections so that transmission lines between separately digitized sections (e.g., across state boundaries) would be continuous. The data are available on two 3½" diskettes in PC-compatible format. (Generated 1991, $300.00)
