| 摘 要： | 针对大跨度钢桥中采用梯形加劲肋的正交异性钢桥面板,提出一种计算钢桥面板局部振动的组合板梁单元法.其中顶板用平板壳单元分析,梯形加劲肋视为板梁单元,两者的位移模式根据板与肋的变形协调关系建立.组合板梁单元的刚度矩阵通过能量变分原理得到,利用各子单元的形函数可以求得组合板梁单元的一致质量矩阵与一致荷载列阵,进而得到相应的有...

| Abstract: | Proposed in this paper is a combined plate-beam element method to calculate the local vibration of the orthotropic steel bridge deck with trapezoid stiffened ribs,which is used in the long-span steel bridge.In this method,the top plate and the trapezoid stiffened rib are respectively taken as the flat shell element and the plate-beam element,and the corresponding displacement model is established according to the deformation coordination relationship between the plate and the rib.Moreover,the stiffness matr... |
