摘要
对2片混凝土灌芯纤维石膏板进行水平往复荷载作用下的恢复力试验,初步探讨这种抗侧力构件的破坏特征、变形能力和延性等受力特性.试验结果表明,混凝土灌芯纤维石膏板受力时作为一个整体共同工作,结构通过纤维石膏板的开裂耗散能量,提高了结构的抗震性能,使结构具有较好的延性.借助AD INA软件建立实体模型分别对混凝土芯柱和纤维石膏板以及组合墙体进行数值模拟,有限元计算结果和试验吻合较好,有限元模型正确合理,可以较真实地模拟结构的受力性能.
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.
