摘要
基于Matlab优化工具箱,以结构内力和线形为控制条件,提出一种便于工程应用的斜拉桥索力优化实用方法。将斜拉桥合理成桥索力的确定问题转化为有约束的二次规划问题,运用Matlab优化工具进行求解,工程算例证明方法简单、有效,具有一定的工程实用价值。
Based on the Matlab optimization toolbox, this paper used internal force and geometry as control conditions, put forward a praetieal method of optimization of cable force for cable - stayed bridge. The problem of contirming the finished - stage cable force for cablestayed bridge was turned into the problem of constrained quadratic programming. Then the problem was solved hy Matlab optimization toobox. The engineering examples showed that the methods was simple, efficient and had practical values in engineering.
