The Earthquake Engineering Online ArchiveDynamic Soil-Structure Interaction in Building Response from Earthquake RecordsSerino, Giorgio UCB/SEMM-1989/01, Dept. of Civil Engineering, University of California, Berkeley, 1989-01, 89 pages The report analyzes the response records obtained from an instrumented, 14 story reinforced concrete structure, the Hollywood Storage Building, in the Whittier earthquake of 1987 and other previous earthquakes to assess to what extent soil-structure interaction modified the response of the building and to evaluate the concept of base shear reduction to represent the effects of soil-structure interaction in design. It is found that the effects of soil-structure interaction are significant in only one of the two main directions of the building. In that direction the analytical model of the complete system indicated a reduction of 16.6% of the base shear during the Whittier earthquake when compared to the structure resting on a fixed base.
