摘　　要：基于合理的单元类型和材料本构关系,采用大型非线性有限元分析软件ABAQUS,对开洞砌体填充墙钢筋混凝土框架结构进行了三维有限元分析,并在试验的基础上进一步研究了开洞率对砌体填充墙钢筋混凝土框架结构性能的影响。结果表明,所建立的有限元模型可较好地模拟开洞填充墙钢筋混凝土框架结构的非线性性能;开洞率越大,砌体填充墙钢筋混凝土框架的承载力越小,但当开洞率超过60%时,其承载力与纯框架相差不大。Abstract： Based on the appropriate element type and material constitutive model, the nonlinear finite element analysis software ABAQUS is used to analyze the infilled reinforced concrete frame structure, and then the effects of the diverse ratio of openings on the behavior of the structure based on the experiment. The analysis results showed that the behavior of mansorny infilled reinforced concrete frame structures with openings can be well simulated by the nonlinear finite element analysis model. The bigger the ratio of openings is, the smaller the bearing capacity will be, but the bearing capacity of infilled frame with openings is close to bare frame when the ratio of openings is over sixty percent.
