高层复合墙板结构体系地震反应分析

Seismic Response Analysis of Tall Building of Composite Wallboard Structure

为把混凝土灌芯纤维增强石膏板应用到高层结构中,选定了墙板厚度类型,并采用材料力学的方法把其简化为正交各项异性板,获得其等效弹性常数,引用Hill屈服准则来建立其本构关系.采用振型分解反应谱法和时程分析法对基于此板型的复合墙板结构体系的高层结构进行弹性和弹塑性分析,计算表明此结构具有足够的刚度和抗侧移能力.并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.

For the purpose of the structural application of fiber-reinforced plasterboard filled with concrete （composite wallboard） in tall building,one wallboard type was selected and the method of materials mechanics was used to simplify it to orthotropic board and equivalent elastic constants were obtained. Hill＇s yield principle was introduced to establish its constitutive relations. Using response spectrum method and time-history analysis method,study on elastic and elastoplastic analysis for the tall building based on composite wallboard structure of this board type was carried out. The calculation results show that the structure has enough stiffness and lateral displacement capacity. Finally the comparison of dynamic characteristics of structure of composite wallboard and shear wall of reinforced concrete proves that the former is superior to the latter in seismic performance.
