摘　　要：为深入研究框架结构的抗震性能,基于ABAQUS有限元软件,建立1栋6层3×4跨钢筋混凝土框架结构有限元模型,对其在不同震级下的动力特性及抗震性能进行研究。对钢筋混凝土框架结构进行模态分析及动力时程分析,得到钢筋混凝土框架结构前10阶自振特性和钢筋混凝土框架结构在7度多遇地震及8度多遇地震作用下的位移响应、最大层间位移角、基底剪力等抗震性能,得出钢筋混凝土框架结构的地震响应时程曲线。Based on ABAQUS finite element software,a finite element model of a 6-story 3×4 span reinforced concrete frame structure was established to investigate its dynamic characteristics and seismic performance under various earthquake magnitudes.Through the modal analysis and dynamic time history analysis of the reinforced concrete frame structure,the first 10 natural vibration characteristics of the reinforced concrete frame structure,as well as the seismic performance of the reinforced concrete frame structure under earthquakes of magnitudes 7 and 8,including the maximum inter-story displacement angle and the base shear,were obtained,and the seismic response time history curve of the reinforced concrete frame structure was acquired.
