| 摘 要： | 为探讨桥梁结构稳定性分析的方法,以二节点平面杆单元为例,采用有限元法推导了桥梁结构稳定问题的单元刚度矩阵,利用所得单元刚度矩阵和FORTRAN语言编制了有限元分析程序,然后对一门式桥墩中墩的结构稳定性进行了分析,并将临界荷载与欧拉公式及ANSYS所得结果进行了比较,从而验证了该单元刚度矩阵和该有限元法的正确性。

| Abstract: | The element stiffness matrix of bridge structure stability was deduced by using the finite element method,which was based on two node 2-D bar element.An analysis procedure of the finite element was developed by using the element stiffness matrix and language of FORTRAN for the stability of piers.At last,the element stiffness matrix and the analysis procedure were verified by comparing the piers analysis result with result of ANSYS and Euler equation. |
