Comparison and Study on Seismic Performance of the Special-Shaped Column and Rectangular Column Frame Structure

Abstract:

By introducing the basic concepts and designing principles of special-shaped column structure, this paper attempts to establish three finite element models (the special-shaped column structure, rectangular column structure with the equal area and rectangular column structure with the moment of inertia) by using the SAP2000. And the basic dynamic structure properties of three structures are analyzed. It’s base of the dynamic analysis for the structure. Then, the paper analyzes the elastic seismic performance under the horizontal earthquake action by using the vibration spectrum method and the elastic time-history analysis method. The results show that three models are all in the elastic steps. We compared the anti-seismic property of three models under frequent earthquake.
