Shaking Table Study of Single-Story Masonry Houses: Dynamic Performance Under Three Component Seismic Input and Recommendations
Five masonry house models have been tested on the earthquake simulator (shaking table) of the University of California at Berkeley, in an investigation aimed at establishing reasonable reinforcement requirements for single - story masonry dwellings in Seismic Zone 2 of the Uniform Building Code. Each of the models was a 16 - foot square masonry house consisting of four wall panels with standard size door and window openings, connected to a timber truss roof to which weights were added in order to obtain realistic loads on the load - bearing walls. This report contains the results of tests of House 5, which was oriented on the shaking table as that its walls were simultaneously subjected to two horizontal components and a vertical component of input motion. Initially the walls of House 5 were unreinforced; then a second series of tests was carried out with the walls partially reinforced. A detailed analysis of the results for House 5 is presented, and the dynamic response of House 5 is compared with the responses of Houses 2 and 4. Finally, by extrapolating the earthquake performance of the test structures by prototype conditions, recommendations are made for requirements for the lengths of the shear-resisting elements of both unreinforced and partially reinforced masonry walls. Six references, tables, figures, and a list of Earthquake Engineering Research Center reports are provided. (Author abstract modified).
