摘要
按材料非线性原理编制出一套避开传统迭代过程的能自动确定加载步长的梁杆组合结构有限元分析软件。该软件不仅成功地运用于高速铁路在桥线纵向相互作用非线性分析中，而且对所有类似的结构都具有普遍的适用性。
According to the principles of materially nonlear finite element method,we developed a set of programs which can automatically choose the force enforcement steps and avoid the traditional process of reiteration.The programs have been successfully used in the analysis of longitudinal interaction between bridge and rail on High speed railway,and its underlying concept is universally adaptable to similar structures.
