摘要
由于斜拉索的锈蚀断丝等损伤必然导致索力及结构内力状态的改变,主梁的挠度也将随之发生变化,本文以一座独塔斜拉桥为例,从主梁挠度及索力的监测方法出发,以拉索损伤的敏感性分析为手段,探讨基于主梁挠度及索力监测的斜拉索损伤识别的方法及其适用性。
Since the rust and damage of the cables will inevitably lead to the change of cable tension and internal structural change, the main beam deflection will subsequently change, so a means to the cable damage identification and its applicability based on the monitoring of deflection and cable tension of main beam are explored and a single tower cable-stayed bridge is given as an example.
