曲线连续刚构桥的结构分析
Structure Analysis of Curve Continuous Rigid Frame Bridge
【摘要】 结合具体工程实例,对曲线连续刚构桥进行结构分析。结果表明:"弯-扭"耦合现象使得曲线连续刚构桥的受力性能与直线桥有明显差异。对小半径、大跨径的曲线刚构桥,有必要对其进行空间结构分析,以更好了解结构的实际受力性能;对半径和跨径比本桥更接近于直线的桥梁,将其简化成直线桥设计,仍然具有很强的理论基础。
【Abstract】 Based on specific project example,the paper makes structural analysis on the curve continuous rigid-frame bridge.The results show that the"bending-torsion"makes mechanical properties of curve continuous rigid-frame bridge significant differences with straight bridge.It is necessary to carry out the spatial structure analysis on the long span of curve rigid-frame bridge with small radius,in order to understand the actual performance of the structure better.The bridge with similar radius and span to the straight bridge will be simplified to a straight bridge,which still has a strong theoretical foundation.
