摘要

为给大跨桥梁结构损伤识别和安全性评价提供可靠的模态参数

利用润扬悬索桥结构健康监测系统（SHMS）记录的主梁加速度响应

基于希尔伯特黄变换（HHT）方法开展了该桥的模态参数识别分析

并进一步研究了"麦莎"台风期间该桥模态参数与所测环境的风速、温度因素间的偶联关系。研究结果表明:基于HHT识别的低频段阻尼比值普遍要大于高频段

阻尼比总体随着频率的增大而减小;识别结果与成桥试验所得现场实测参考值以及有限元值几乎吻合

验证了该方法的可靠性;台风期间各阶模态的频率相对稳定

受风速、温度影响程度小;模态阻尼比的波动性则较为明显

受风速、温度影响较大。研究结果可为更好地掌握台风期间大跨度悬索桥的动力特性及其全过程变化规律提供参考。

Abstract

In order to provide reliable modal parameters for structural damage identification and security evaluation of long span bridges

the modal parameter identification of Runyang Suspension Bridge was conducted based on the Hilbert-Huang Transform（HHT）methods.The structural acceleration responses used for parameter identification are obtained from the structural health monitoring system（SHMS）of the bridge.The relationship between structural modal parameters and environmental factors including wind speed and temperature during typhoon"Matsa"is further studied.The results show that the identified damping ratios based on HHT methods at low frequency are generally greater than those at high frequency.The damping ratio decreases as the frequency increases.The recognition results are in good agreement with the measured values obtained by the bridge test and the finite element values

and the reliability of the method is well verified.During the typhoon

the frequency of each mode is relatively stable under the influence of wind speed and temperature.However

the volatility of modal damping ratio is very obvious under the influence of wind speed and temperature.Conclusions can provide reference for better understanding of the dynamic characteristic and its variation of long span suspension bridge during typhoon.
