京包高速公路上地斜拉桥自振特性反应分析

The Reaction analysis Of Self- vibration characteristics of cable- staye d bridge on Beijing- Baotou expressway

包高速公路工程上地斜拉桥为五跨连续独塔单索面预应力混凝土斜拉桥,利用ANSYS有限元分析软件对该桥进行了多种工况下的承载能力分析,并对该桥进行了地震反应分析。经分析及验算表明本设计计算方法正确且内力分布合理,符合设计任务要求。

The highway engineering cable-stayed bridge is a five span continuous cable-stayed bridge with single tower. The bridge bearing capacity was analyzed under various conditions using ANSYS. The analysis and calculation show that the design calculation method is correct and the internal force distribution is reasonable, and it is in accordance with the design requirements.
