Abstract

The Strong Motion Instrumentation Program of the California Division of Mines and Geology (CSMIP) has obtained records of the response of four buildings with unreinforced masonry (URM) infills. The response was to the Landers, Upland and Sierra Madre earthquakes. The objective of this research was to replicate by computer analysis the CSMIP records.

Three dimensional elastic computer models were prepared from data obtained from the original construction documents. The URM infills were modeled as diagonal braces in the frame. The stiffness properties of the infills were determined by a nonlinear finite element analysis.
