摘要
研究钢筋混凝土框架结构内部填充墙对框架的抗侧刚度、承载力及变形能力的影响。采用混凝土塑性损伤模型及黏性接触面单元模拟填充墙砌块及砂浆,对框架填充墙砌体进行了精细化建模,并模拟框架的面内水平位移加载,得到填充墙砌体在不同加载阶段的裂缝开展形态及外框架结构的损伤情况。将数值模拟结果与试验值进行了对比,为带填充墙框架的有限元精细化模拟及分析提出了一种可行的方法。
The effects of infilled walls on lateral stiffness, loading capacity and deformation capacity of the reinforced concrete frame structure were investigated. Finite element models of reinforced concrete frame structure with infilled walls were established by the method of simulating masonry with concrete damaged plasticity elements and simulating mortar joints with cohesive zone elements. Simulation results were com- pared with experimental results. A method for simulating reinforced concrete frame structure with infilled walls was provided.
