Structural Health Monitoring and Buffeting-Induced Fatigue Damage Assessment of Long Suspension Bridges
As modem suspension bridges become longer and longer, buffeting-induced fatigue damage problem for the bridges located in strong wind regions may have to be taken into consideration. Furthermore, there is a trend to install wind and structural health monitoring systems (WASHMS) to long suspension bridges for performance assessment. A systematic framework for assessing long-term buffeting induced fatigue damage to long suspension bridges is thus presented in this paper by integration of the joint probability density distribution of wind speed and direction, the structural health monitoring- orientated finite element model of the bridge, the numerical procedure for buffeting-induced stress analysis, and the continuum damage mechanics (CDM)- based fatigue damage assessment method. The framework is then applied to the Tsing Ma Bridge in Hong Kong. It is found that the proposed framework is feasible and practical.
