摘要

摘要: 从数值模拟和试验方面进行了灵敏度分析的结构损伤识别方法的验证，数值模拟分析了3种情况下的识别精度和结果，对框架结构模型进行了试验研究。数值模拟和试验研究结果清楚地表明：对于剪切型结构，利用灵敏度分析的方法可以确定损伤的位置，同时确定损伤的程度。

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.
