【摘要】 在对纯RC框架进行有限元模拟基础上,采用连接单元模拟填充墙中砌块与砌块、填充墙与框架梁柱的连接性能,并通过对连接单元的参数调节以实现进一步的数值模拟.随后,结合均匀设计表建立填充墙钢筋混凝土(RC)框架结构逐步精细化有限元数值模拟模型,进行对连接单元属性不一致情况下模型的有限元分析.同时,在得到相近似的上升段有限元模型后,利用单元生死技术对模型下降段进行模拟分析.通过将模拟的试验结果与真实实验结果进行比较,证实本文所提出的对填充墙RC框架结构有限元数值模拟方法的可行性.更多还原

【Abstract】 Based on the finite element simulation of the pure reinforced concrete frame,this paper utilizes the connected element to simulate the connected performance between the two blocks,as well as the infilled masonry wall and pure reinforced frames;and it also realizes the further numerical simulation through the regulation of the parameters.And then,it establishes the gradual refinement finite element numerical simulation model under the uniform design table to analyze the model that contains inconsistent connected element.At the same time,this paper simulates the decline period of the load-displacement curve with the technology of the birth and death element after obtaining the similar rise period of the finite element model.By comparing the test results,to verify the feasibility of the finite element numerical simulation method proposed in this paper.更多还原
