Abstract: The dynamic response of 23 structures instrumented by the California Strong Motion Instrumentation Program was recorded during the magnitude 6. 2 (ML) Morgan Hill earthquake of 24 April 1984. The structures range in complexity from a single-story warehouse to a 13-story office building. The strong motion records from seven buildings and one bridge have been digitized and processed. Maximum horizontal ground accelerations at the buildings were in the range 0. 03-0. 11 g; maximum roof accelerations were 0. 17-0. 41 g. Processing of the digitized data indicates that the maximum horizontal displacements at roof level ranged from 1 to 19 centimeters. Significant structural response lasted for less than 35 seconds for most buildings. However, the steel-frame Santa Clara County Office Building had significant response for about 80 seconds.
