Damage Identification Method Research Based on the Change Rate of Strain Mode
Abstract:
Damage identification method based on the change rate of strain mode is studied in this paper. Reinforced concrete frame structure as a researching object, true strain mode of structure is obtained by external excitation, graphics of strain mode and change rate of strain mode of the frame structure before and after the damage are established and analyzed. The results show that the change rate of strain mode is sensitive to the damage, and the location and extent of the damage can be judged through this method.
