摘　　要：基于纤维增强石膏板组合墙体的抗震性能模型试验,采用ANSYS参数化程序设计语言(APDL)编制了命令流,对模型墙体在侧向和竖向荷载共同作用下的破坏特征和整体结构的抗震性能进行了非线性有限元分析。研究了钢筋混凝土芯柱和纤维增强石膏板对墙体抗侧承载能力的影响。计算结果与试验结果吻合较好,分析结果说明纤维增强石膏板组合墙体具有良好的抗震性能。Based on the model experiment on seismic behavior of composed-wall-specimens made of fiber-reinforced plasterboards（ CFFRP） ,a command stream is edited with the ANSYS Parametric Design Language （APDL） ,and the nonlinear finite element analysis of the structure on the seismic behavior and model walls under horizontal-low-cyclic loading with constant vertical loading is completed. According to those above ,the effect of the core columns ,fiber-reinforced plasterboards on the failure feature and fundamental seismic behavior of such walls have been analyzed. The calculated results are much coincided with the tested results. The analysis results showed that composite walls made of fiber-reinforeed plasterboards bad excellent seismlc-resistant behavior.
