刚构一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一斜拉协作结构桥梁的设计参考.
剛構一斜拉協作體繫是一種新型組閤結構,計算與分析參攷資料較少.斜拉索索力直接影響到斜拉部分和剛構部分的剛度分配,對結構整體受力的閤理性至關重要.以控製結構在正常使用荷載作用下以最大、最小應力為主要目標,在"閤理恆載彎矩域"範圍內,建立索力優化模型,調整結構達到理想成橋狀態.該文的研究成果可供今後剛構一斜拉協作結構橋樑的設計參攷.

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 within the range of "reasonable dead load bending moment domain" to adjust the structure up to the ideal completed bridge status. The study result of the article can be referenced for the design of the rigid-frame-cable stayed collaboration structural bridge.
