Abstract

In order to analyze the quantitative influence of the axial compression ratio on the seismic performance of reinforced concrete (RC) frame column, this paper carried out the numerical analysis of the quasi-static simulation of a RC frame column and analyzed its hysteresis performance, bearing capacity, stiffness degradation, energy consumption capacity and ductility capacity under different axial compression ratios, based on OpenSees finite element software, considering the buckling and fatigue damage model. The results show that the smaller the axial compression ratio, the fuller the hysteresis curve and the slower the stiffness degradation of the column. The ultimate bearing capacity of the column increases by 24.6% when the axial compression ratio increases from 0.3 to 0.8, but bearing capacity decreasing and stiffness degradation is faster and faster. When the deformation does not exceed the ultimate displacement, the equivalent viscous damping at each displacement level of high axial compression ratio column is greater than that of the low axial compression ratio, but the total hysteretic energy decreases about 64.2% at maximum amplitude. The ultimate displacement gradually decreases with the increase in the axial compression ratio, and the ductility factor decreases about 55.9% at maximum amplitude. The results can be referenced by the seismic design and analysis of RC frame.
