NUMERICAL STUDY OF DAMAGE LOCALIZATION FOR TSING MA BRIDGE DECK

Wang Baisheng(Zhejiang University) Y.Q.Ni J.M.Ko(Hong Kong Polytechnic University)  
A damage localization for the Tsing Ma bridge deck is studied through a business program in the paper.A two-stage method is employed for the damage localization.In the first stage,the Tsing Ma bridge deck is divided into several segments.A damage index is derived from modal components for indicating the damaged region.That means to identify where is the damaged deck segment.In the second stage,the artificial neural network is used to identify damaged member in a damaged segment.The results show that the proposed method is feasible for the damage localization of a deck structure.
