The Strong Motion Instrumentation Program (SMIP) of the California Department of Mines and Geology has obtained significant records in a number
of steel structures. The objective of this research was to conduct comparative studies of the response of two modern steel structures as predicted
by current analytical methods and the response recorded by SMIP.
Realistic models of the structures were developed and were subjected to 3-dimensional dynamic analyses. The analyses indicated that proper modeling
of connections, and floor diaphragms can lead to accurate predictions of the response. Also, current code procedures predict a period that usually
is significantly smaller than actual period of vibration.
