    摘要
  • 摘要: 基于力法基本原理,参照JTG D60-2004的规定,对桥梁设计中较常使用的一类实用手工查表算法-刚接板梁法,采用横向自动加载优化的方法,进行了Fortran 90程序设计,实现了自动求取桥梁荷载横向分布系数.给出了算例分析,说明了方法及程序的正确性和可靠性.

     

    Abstract: The computational programs were designed by Fortran 90 based on the principles of force method in structural mechanics, and by means of the optimized lateral auto-loading approach according to the 2004 criterion (JTG D60-2004) for the models of slab (girder) with transverse rigid joints, which are applied frequently to be a kind of practical manual algorithms in bridge design. A numerical example was given to show the conciseness of the method and the reliability of the programs.It was proven that this method would be important for structural design of bridges, and would make it possible to calculate the lateral distribution coefficients of bridge loading automatically.
