【Abstract】 In this paper, several practical implementations of health monitoring for bridges are reviewed. Actuality of damage identification for structures is expatiated and comments are made on the methods of them. Considering that curvature mode shape can identificate the damage of structures and locate it, the theoretical basis of curvature modal analysis is discussed emphatically in the paper. The applications of curvature modal analysis in damage detection are probed into. Finally, several problems which should be regarded in the actual work of damage identification for structures are put forward and conclusions are given.更多还原
