| 摘 要： | 本文将均质化理论引入混凝土灌芯纤维增强石膏板(简称复合墙板)的计算。建立了复合墙板的代表性体积单元(RVE)模型,应用有限元分析程序ANSYS对此RVE模型进行模拟,获得其等效弹性常数,为结构的有限元计算提供了有效途径。对一复合墙板结构试点工程进行动力特性测试,测试结果与均质化的计算结果比较吻合,表明这种模型用于计算复合墙板结构的可行性。最后将复合墙板结构与钢筋混凝土剪力墙结构的动力反应特性进行了比较,结果表明复合墙板结构具有优于钢筋混凝土剪力墙结构的抗震性能。

| Abstract: | In this paper,the theory of homogenization is introduced into the calculation of fiber-reinforced plasterboard filled with concrete(composite wallboard) and the representative volume element(RVE)model of composite wallboard is established.Elastic constants of RVE are obtained by using FEA software ANSYS.This provides an effective way for FEA calculation.By the measurement of dynamic characteristics for an experimental structure of composite wallboard,the tested results agree well with the analytical ones of homogenization.This proves the feasibility of RVE model for calculating the structure of composite wallboard.Finally the comparison of dynamic characters of structure of composite wallboard and shear wall of reinforced concrete proves that the former is superior in seismic performance to the latter. |
