Curvature Mode Shapes-based Damage Identification Method

CHEN Jiang,XIONG Feng (School of Architecture & Environment,Sichuan University,Chengdu 610065,China)  
A damage identification approach applied aptly in bridges and continuous beams,based on the curvature mode shapes,was studied in this paper.The influence from using different mode shapes,various damage degree and changing the number of measure points,was compared by computing a 2D frame finite element model.The variety of damage location and the random error in terms of measurement noise in real project were considered.Some basis was got for the engineering application.The simulated experiment showed that this method could detect crack location preferably and give a qualitative description for the damage degree.
