Discussion on Damage Detection of Bridges Using Curvature Mode Method

YU Dan-jiang, CHEN Huai (College of Civil Engineering,Zhengzhou University,Zhengzhou 450002,China)  
Based on numerical simulation, the curvature modal method used in damage detection of bridges is discussed.The curvature mode is very sensitive.When curvature mode is used in the damage detection of bridges,it can locate the damage accurately before adding noise to displacement mode.Here the result has high precision and can identify the damage.When the noise added to displacement mode is lower than 1%,its influence is indistinct,but the damage can still be detected.When the noise is higher than 1%,the damage cannot be located.
