摘要
在分析斜拉桥索力影响矩阵的基础上,以结构应变能最小为目标函数,建立了无背索部分斜拉桥索力优化模型,结合某旅游路立交桥进行索力优化分析,得出了一些具有一定参考价值的建议。
It create cable force optimality model of backless cable partially stayed-cable bridge based on cable force influence matrix of stayed-cable bridge and objective function of the structure with least strain energy,and proceed cable force optimality analysis incorporated something tour way overpass bridge,make some valuable conclusion through this article.
