摘要
借助Midas Civil有限元分析软件对某矮塔斜拉桥进行成桥状态温度效应影响分析,根据多塔矮塔斜拉桥的特点,揭示了结构整体升降温、索梁温差以及主梁温度梯度对主梁变形、索力以及主梁应力的影响规律,分析结果可供同类设计参考。
Analysis of temperature effect on complete bridge state of an extradosed cable-stayed bridge by using the finite element software midas civil.According to the features of the extradosed cable-stayed bridge,it reveals the law of the main beam deformation,cable force and the stress of the main beam which is act by the temperature rising and reduction of the overall structure,the different temperature between the beam and cable,temperature gradient of the grider.The analytic result can offer a reference for the designment of the similarity type of multi pylon extradosed cable-stayed bridge.
