Abstract

Abstract

In order to verify the modal sensitivity based on damage identification method, numerical simulation is performed in three types of cases.This method is further evaluated by vibration test of a frame model.Numerical simulation and experimental verification clearly show that for the shear buildings, damage severity and locations can be detected by the method.
- damage identification,
- frame structures,
- numerical simulation,
- vibration test
