In order to consider the geometrically nonlinear behavior of suspension bridge structure , the tangential stiffness matrix of the assembled element and that of the spatial bar element were formulated 根据等参单元的大变形理论,推导了组合单元的切线刚度矩阵,以适应悬索桥的几何非线性分析。
Then bar element ' s tangential stiffness matrixes are deduced , which is based on the finite element method . the geometrical nonlinearity and material nonlinearity are both considered in the non - linear element stiffness matrix 利用有限元方法,对网壳结构进行了几何和材料非线性分析研究,推导了空间铰接杆单元的几何和材料非线性的刚度矩阵。
