The Strong Motion Instrumentation Program (SMIP) of the California Dept. of Mines and Geology has obtained significant records in a number of steel structures. The objective of this research was to conduct detailed comparisons of the response of a modern steel structure predicted by current analytical methods and the response recorded by SMIP. The details of the structure are presented together with the instrumentation programs and data processing. Fundamental system identification techniques were used to identify engineering design parameters such as periods, modal shapes, and damping by interpreting the recorded response to the 1987 Whittier, California, earthquake. A realistic model of the structure was developed and subjected to three-dimensional dynamic analysis. The results consider the proper modeling of connections and floor diaphragms in order to accurately predict response.
