| 摘 要： | 介绍了对格子梁体系进行静载机构破坏极限承载力分析的一种方法──残余弯矩系数法．残余弯矩系数法不仅可以处理单片梁，也可以处理格子梁体系，即可以用于自动适应（ｓｈａｋｅｄｏｗｎ）分析，也可以用于静载机构破坏极限承载力分析．将该方法用于例桥和实验桥的分析中，结果表明，残余弯矩系数法具有足够的精确性．针对这一方法，编制了一套软件程序ＺＤＳＹ．

| Abstract: | A new analysis method for grid girders,residual moment factor method, which is used to analyze the static limit loads, is developed. The method solves not only single girder but also bridge deck. Some sample bridges and test bridges are analyzed with residual moment factor method. The results show that the residual moment fator method is accurate enough. A software called ZDSY based on residual moment factor method is developed. |
