| 摘 要： | 为抗震设计的墙板计算提供新的计算方法,基于已有的微观及宏观计算模型和纤维模型概念,建立了用于研究速成墙板等组合墙体的非线性分析的宏观纤维计算模型,即每个墙体单元由宏观纤维子单元和宏观剪切子单元组成,分别抵抗轴力、弯矩及剪力。推导了模型的单元刚度矩阵和各杆件的刚度。运用计算模型对4块满灌混凝土石膏板进行了推覆分析,并与试验结果进行了比较,表明该模型具有较好的精度。

| Abstract: | According to the idea of micro-and macro-model,a macro-model basing on the idea of fiber model is put forward,which is applied to analyze nonlinear characteristic of composite wall.The macro-model is composed of macro fiber element that only resist axis force and moment,and macro shear element that only resist shear force.Stiffness matrix of the model and element stiffness is provided.The elasto-plastic push-over is carried out to the four fiber plasterboard filled with reinforced concrete with the macro-model.The computational results are close to those of experiments,which show that the model has relatively high accuracy. |
