混凝土板墙加固砖砌体墙抗剪性能的有限元分析

摘要

通过对混凝土板墙加固一榀砌体墙的抗剪性能进行非线性有限元分析和理论计算,就砌体材料本构、模型建立、参数选取等进行了探讨.结果表明,只要建模适当,就可以采用ANSYS软件对混凝土板墙加固砌体墙的抗剪性能定量地进行有限元分析,并能较准确地模拟实际结构的承载力状况.%Based on finite-element analysis and some other theoretical analysis methods, the shear behaviors of one pin masonry wall strengthened with the concrete wall have been researched, constitutive behavior, selection of modle for masonry structure, parameters choice, etc. Were discussed. The results showed that; so long as the appropriate modle was chosen, the shear behaviors of concrete wall could be analyzed quantitatively with ANSYS software,and bearing capacity of real structure could also be simulated accurately.
