刚构—斜拉协作体系的索力优化

刚构-斜拉协作体系是一种新型组合结构,计算与分析参考资料较少。斜拉索索力直接影响到斜拉部分和刚构部分的刚度分配,对结构整体受力的合理性至关重要。以控制结构在正常使用荷载作用下以最大、最小应力为主要目标,在"合理恒载弯矩域"范围内,建立索力优化模型,调整结构达到理想成桥状态。该文的研究成果可供今后刚构-斜拉协作结构桥梁的设计参考。

Cable Capacity Optimization of Rigid-frame-cable-stayed Collaboration System

The rigid-frame-cable-stayed collaboration system is a new type of composite structure.There are a few references of calculation and analysis.The stayed cable capacity directly affects the rigidity distribution of cable-stayed part and rigid-frame part,which is important to the rationality of the integral bearing of the structure.Taking to control the maximum and minimum stresses of the structures under the loading action of the normal use as the main aim,the cable capacity optimization model is set up with...
