| 摘 要： | 视钢管混凝土为复合材料 ,建立了钢管混凝土拱结构计算的矩阵位移法。在对横截面作空间有限元子结构分析的基础上 ,利用平截面假定 ,将空间子单元转换为杆单元 ,从而导出了杆元的刚度矩阵。如进一步深入 ,可应用到钢管混凝土拱的非线性分析中。

| Abstract: | Regarding the concrete filled steel tube as a composite material, this paper proposes a new matrix displacement method for analyzing concrete filled steel tubular arch structures. On the basis of sub structure analysis of cross sections by space finite element method, space sub elements are transformed to beam elements of matrix displacement method by plane section hypothesis. Thereby the stiffness matrix of the beam elements is obtained. If further researched, the method can be applied to nonlinear analysis of these arch structures. |
