桁架梁

In the program the Newton-Raphson's method is used to iterative computation; and the method of either the cylinder-arc-length or the minimum residual displacement is adopted to control the iterative process.

在分析非线性静力和动力有限元计算方法的基础上，本文采用修正的Newton-Raphson方法进行迭代计算，并采用柱面弧长法和最小残余位移法控制迭代过程，编制了一个适合于杆件体系结构的有限元分析程序，结构可以按桁架、刚架或梁杆组合体系分析。

After studying the curve of the vibration frequencies, which are varying with the changing of the structural parameters such as the rigidity of pier, the rigidity of straining beam, the rigidity of truss, the high of pier, the width of deck, and so on, some rules about the changing of vibration frequencies and the influencing of the structure that vary with the parameters were achieved.

研究了桥墩刚度、横系梁刚度、桁架片刚度、桥墩高度、桥面宽度等参数对结构动力特性的影响，通过对结构的自振振型及频率进行相应分析，得出结构参数变化对结构的横向刚度、竖向刚度、纵向刚度和扭转刚度及其他动力特性的影响程度及规律。
