钢筋混凝土叠合墙体非线性仿真研究

摘要

A kind of new half prefabricated composite wall is introduced in this paper including the current situation of application, and the mode of construction. Typical specimens were tested under reversed cyclical loading, and the numerical simulation was also carried out to the tested specimens. The simulation models were set up considering the bond property and the longitudinal steel bars at the boundary area. The calculated results agree to the tested results. The lateral bearing capacity of the half prefabricated composite walls are believed good, and the prefabricated part can work well with the cast in place part in this kind of composite walls.%介绍了一种半预制半现浇钢筋混凝土叠合墙体的应用现状、构造方式及钢筋混凝土叠合墙的低周反复试验.在试验基础上用DIANA软件,对单调加载作用下半预制半现浇钢筋混凝土叠合墙体的受力性能进行数值计算,所用的分析模型考虑了边缘纵筋,还考虑了预制部分和现浇部分结合的黏结特性.计算分析结果与试验结果符合良好.半预制钢筋混凝土墙体具有良好的抗侧性能,新老混凝土协同工作性能良好.
