曲线梁桥以直代曲简化算法的适用性研究

Study on applicability of replacing the curve with a straight line to simplify the algorithm for curved girder bridge

结合某一曲线梁桥,对曲线梁桥的计算中,当曲线梁桥曲线半径较大时,常采用的以直代曲的简化计算方法的适用性进行讨论比较,为同一类型的桥梁设计提供参考。

In combination with a curved girder bridge, and in its calculation, when the curve radius of the curved girder bridge is big, the applicable conditions of the simplifying calculation method of replacing the curve with a straight line were discussed and compared, which can provide reference for design of similar bridges.
