Strong motion records were recovered from nearly fifty stations of the California Strong Motion Instrumentation Program (CSMIP) following the Morgan Hill earthquake of April 24, 1984. Twenty-three of those stations were extensively-instrumented structures. This report presents results of the digitization and processing performed on the records obtained from eight of these structures, including seven buildings and one bridge. The unprocessed records for the remaining structures typically had maximum accelerations of 10% g or less, as shown in the data report by Shakal et al. (1984), and were not digitized. The results for the digitization of strong-motion records obtained at CSMIP ground-response stations are presented in an accompanying Part I report (Sherburne et al., 1985). Strong-motion records obtained by other agencies such as the U.S. Geological Survey (USGS) are described in the paper by Brady and Shakal (1985); the digitization results obtained by the USGS for those records are given in Brady et al. (1984).
