建筑结构在经历地震发生破坏后,其自身动力特性发生改变,通过了解这些动力特性的参数变化可以判断结构破坏的程度。而普通计算分析程序对带损伤结构的动力特性计算一般存在困难。文中讨论了一种实现损伤结构动力特性模拟的方法,利用通用程序ABAQUS实现了这一过程,最后对一个工程实例进行计算分析,并和常用的简化估算方法进行对比,结果表明本文方法的计算结果具有较好的可靠性。
After experiencing earthquake damage, the building structure changes its own dynamic characteristics. By knowing the change of parameters of these dynamic characteristics, the degree of structural damage can be judged. Ordinary calculation and analysis procedures generally have difficulties in calculating the dynamic characteristics of damaged structures. In this paper, a method to simulate the dynamic characteristics of damaged structures is discussed. This process is realized by the general program ABAQUS. Finally, an engineering example is calculated and compared with the simplified estimation method. The results show that the calculation results of this method Has good reliability.
