摘要：
In this paper the curvature mode is presented to identify and locate the crack damage of concrete structures. A cantilever is analyzed by finite element method and the damage indices of the perfect structure and damaged structure are obtained. Then curvature mode is used to analyze the single damage and multi-damage quantification and damage location. Numerical simulation results show that the changes of curvature mode shapes are sensitive to the damage in the structure. Thus the curvature mode shapes can indicate presence and severity of damage and locate damage at the same time. The curvature mode shape is also suitable for detection of multiple damages. This method has certain guiding sense to damage identification in actual structures.
