Strong-Motion Earthquake Accelerograms Digitization and Analysis, 1971Records,

摘要

This is the first of a series of reports planned to include the results of digitization and routine analyses of strong-motion earthquake accelerograms. Serving as a model for this effort is the collection of data reports published by the Earthquake Engineering Research Laboratory during the years 1969to 1975and covering significant records of the period from 1933up to the San Fernando Earthquake of February 9, 1971. This report covers the significant records of 1971subsequent to the San Fernando Earthquake. The following five records are included: Isabella Dam,California,March 8, 1971; Adak,Alaska, U.S. Naval Base,May 1, 1971; Santiago,Chile,University of Chile,July 9, 1971; Ferndale City Hall,California,September 12, 1971;and Lima,Peru,Institute Geofisico,November 2l9, 1971. An arbitrarily selected peak amplitude of 5% g has been chosen as the main criterion for a record to be considered significant,if it is ground level record,and 10% g if an upper story structural record. The standard data processing for accelerograms is explained.
