摘　　要：对结构动力模型修正的灵敏度分析法作了介绍,通过对四层平面框架的动力模型修正进行研究,研究表明,对于本算例的大部分情况,灵敏度分析法能得到理想结果,但同时也存在部分不理想的情况,建议在实际应用中,可先使用灵敏度分析法进行模型修正,再结合其他方法进行检验。The sensitivity analysis method in structural dynamic model updating is introduced in the paper. The sensitivity analysis method was carried out and the method was simulated with a four plane frame. According to the simulation results, the sensitivity analysis method can get ideal results in usual damage condition, but the method can not get ideal results in some damage condition. The sensitivity method can be used in practical work, and the other structural dynamic model updating method should be used as a auxiliary tool to confirm the results.
