LINEAR AND NONLINEAR SEISMIC RESPONSE OF A 52- STOREY STEEL FRAME BUILDING

摘要

This paper presents the results of a study on the seismic behaviour of a well-instrumented 52-storey steel frame building in Los Angeles, California. This building has been subjected to ground motions from several earthquakes among which the records obtained during the 191 Sierra Madre earthquake and the 1994 Northridge earthquake were selected for this study. Detailed time and frequency domain analyses of the recorded motions from these two earthquakes were conducted to determine the dynamic characteristics of the structure.
