Abstract

Abstract

In order to simplify the seismic response analysis model of the steel reinforced concrete spatial frame with special-shaped columns, a two-direction two-bay eight-story steel reinforced concrete spatial frame with special-shaped columns was taken as the original analysis model. Based on the finite element software platform of OpenSees Navigator, the spatial frame under bidirectional earthquakes, the spatial frame under unidirectional earthquakes, and the plane frame under unidirectional earthquakes were established as the research objects. In particular, the plane frame had the same period with the spactial frame by adjusting the width of subordinate area. By comparing and analyzing the seismic response of the three models, such as acceleration responses, displacement responses, basement shear versus top displacement hysteresis curve, energy dissipation capacity, et al, the rationality of simplified method was verified. The results showed that the dynamic responses of the three models under different earthquakes were similar, and it was feasible to carry out seismic response analysis by using the steel reinforced concrete plane frame with special-shaped columns after quality adjustment to replace the spatial frame.
