摘要
大跨度桥梁由于在交通运输中的重要作用,其安全性已成为人们所关心的热点问题。近年来,桥梁健康监测系统得到了广泛的研究与应用,对于桥梁的长期监测和状态评估一个准确有效的基准有限元模型是不可或缺的。本文基于上海长江大桥主航道斜拉桥健康监测系统的监测数据,对建立的初始有限元模型进行修正,得到更符合桥梁真实状况的基准有限元模型。
Due to its important role in transportation, the safety of large span bridge has become one of the hot issues of concern. In recent years, the bridge health monitoring system has been extensive study and application. An accurate baseline finite element model for long-term monitoring and condition assessment of the bridge is indispensable. In this paper, the model updating of the initial model based on the measured modal parameters was conducted in order to get the baseline finite element model that is more in line with the real Situation of the bridge.
