某铁路大跨度斜交预应力框构桥设计体会

Experience on the design of the railway large-span skew prestressed frame structure bridge

对某铁路大跨度斜交预应力框构进行了分析,利用M IDAS空间分析程序建模,从结构力学模型简化、预应力模拟等方面对这个特殊框构进行计算分析,得出其安全可靠及值得推广的结论。

This paper analyzes the railway large-span skew prestressed frame structure bridge,establishes model by using MIDAS spatial analysis program,and calculates and analyzes the special frame from structural mechanics model simplification,and prestressed simulation and other aspects,and concludes that is safe and reliable and worth promoting.
