| 摘 要： | 有限元法在结构分析中的应用已经非常成熟,但是在很多具体模型中,由于要求不一样,结构单元刚度矩阵和单元质量矩阵需要考虑的内容不一样,因此结构单元刚度矩阵和单元质量矩阵的型式和内容也有所区别。文章采用理论方法推导出渡槽结构考虑剪力滞影响的单元刚度矩阵,使有限元法在渡槽结构的非线性结构反应分析中得到应用。

| Abstract: | Finite element method is well used in structural analysis.However,for many specific models,requirements are different,and element stiffness matrix and element mass matrix are different,too.That restricts the use of finite element method in some fields.This article deduces new element stiffness matrix of the aqueduct by considering shear lag effect so that the method can be used in aqueduct structure non-linear response analysis. |

| Keywords: | finite element method shear lag aqueduct element stiffness matrix |
