混凝土-石膏板计算模型与实际工程动力测试摘 要：本文将均质化理论引入混凝土-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。通过对一复合墙板结构试点工程进行的动力特性测试，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。最后对复合墙板结构与钢筋混凝土剪力墙结构的动力反应特性作了比较，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。关键词：纤维增强石膏板；等效体积单元；均质化；有限元分析；动力特性；地震反应Calculation Model of concrete-plasterboard And Analysis on DynamicCharacter of Experimental StructureAbstract: In this paper, theory of homogenization was introduced into the calculation of concrete-plasterboard (composite wallboard) and Representative Volume Element（RVE）model of composite wallboard was established. Elastic constants of RVE are obtained by using FEA software, ANSYS to simulate, which provide an effective way to FEA calculation. By the measurement of dynamic characteristics for an experimental structure of composite wallboard, tested results agree well with analytical ones of homogenization, which proved the feasibility of RVE model to calculate structure of composite wallboard. Finally the comparison of dynamic character of structure of composite wallboard and shear wall of reinforced concrete proved that the former is superior in seismic performance to the latter.Keywords: Fiber-reinforced Plasterboard ；Representative Volume Element （RVE）； Homogenization ；Finite Element Analysis ；Dynamic 1.前言混凝土灌芯纤维增强石膏板建筑体系具有防火、自重轻、抗震性能好、施工简便等优点，其进展和应用顺应了我国墙体材料改革的需要，是一种很有推广前途的建筑体系。该体系中的基本承重构件——混凝土灌芯纤维增强石膏板（以下简称复合墙板）是在工厂制作定型的纤维增...
