对两种纤维增强石膏板在水平循环荷载作用下的破坏形态、变形能力和延性特性进行了试验研究，结果表明，纤维增强石膏板与混凝土芯共同抵抗荷载作用，地震能量通过石膏板开裂耗散，采用有限元分析程序ADINA，分别对混凝土芯墙、纤维增强石膏板和复合墙体的受力性能进行了分析，计算结果与试验结果吻合较好，表明该有限元模型适用于这种情况。
The restoring-force test of two fiber-reinforced plasterboards filled with concrete under horizontal cycle loading were carried out.Based on the experiments,the behavior of the damage state,the capacity of distortion and the ductility features were investigated.Testing results indicate that the concrete core and fiber-reinforced plasterboard work together to resist load effects,the earthquake energy is dissipated by the plasterboard cracking,and the seismic behavior and displacement ductility are increased.By using the finite element analysis program ADINA,the calculation model was set up to analyze the behavior of concrete core,fiber-reinforced plasterboard and the composite wall respectively.The results calculated by FEM are coincident with the testing ones,indicating that the FEM model is appropriate for this case.
