摘　　要：工程结构在使用的过程中,由于载荷的作用将产生不同位置、不同程度的损伤。为了保证结构的安全,需要及时诊断出这些损伤的位置,以便对结构使用的可靠性进行合理的评估。笔者提出了一种基于类柔度拟合的结构损伤诊断方法,用损伤系数作为诊断损伤的敏感因子,而需要知道结构损伤前即完整结构的参数信息。详细讨论了该方法,用仿真算例说明了这种方法的有效性和可行性,并用实验验证了这种方法的有效性和可行性。During operation of engineering structure, the load will result in different position, different degrees of damage. In order to ensure the safety of structure, the need for timely diagnosis and the damage position, in order to conduct a reasonable assessment of the reliability of structure using. The author puts forward a structural damage diagnosis based on analogous flexibility fitting method, takes the damage index as the sensitive factor of diagnosing damages, and need to know the structural damage of the parameter information of structure. The method is discussed in detail in this paper, an example is given to show the feasibility and effectiveness of this method. And the experimental results show the feasibility and effectiveness of this method.
