本文根据矩阵位移法原理,采用线性子程序迭代的方法,对军用组合吊桥按平面结构进行了非线性静力分析,并编制了相应的FORTRAN 程序,可适用于吊杆不等间距布置、加劲梁为变截面及带斜拉索的多跨组合吊桥,具有一定的通用性,收敛速度较快。用算例与其它方法计算结果进行比较,所得结果合理。 According to the principle of matrix displacement method, a linear subroutine iterative method is adopted to conduct nonlinear static analysis of the military composite suspension bridge according to the plane structure and a corresponding FORTRAN program is prepared, which can be applied to unequal arrangement of boom, For the variable cross-section and the multi-span suspension bridge with suspension cable, has a certain versatility, faster convergence. Compared with other methods, the result is reasonable.
