项目摘要

The efficient computational system of structural damage identification analysis for several models of the structure was established with filtering theory of stochastic dynamic system in a frame work of the inverse problem. In our computational system, three kinds of filtering algorithms based on the Wiener filter, the projection filter and the parametric projection filter were employed to identify some state of damage in member of the structure.Not only the grade but also the position of the member subjected to some damage is identified by our computational procedure with use of monitoring data given by numerical computation or field experiment on eigen-frequencies of the damaged structure. Five-story frame structure (with and without the brace), truss structure (planar and spatial tower-type truss) and large scaled floating offshore structure were adopted as our structural model in order to verify applicability and efficiency of our established computational system.The notable characteristics of each filtering algorithm in applying structural damage identification analysis were made clear through several numerical simulation and experimental performances.
在反问题的框架下,应用随机动力系统滤波理论,建立了多种结构模型的结构损伤识别分析的高效计算系统。在我们的计算系统中,三种滤波算法的基础上维纳滤波器,采用投影滤波器和参数投影滤波器来识别结构构件的某种损伤状态,利用数值计算或现场实验给出的监测数据,通过我们的计算程序,不仅识别出遭受某种损伤的构件的等级,而且识别出遭受某种损伤的构件的位置。受损结构的频率。为了验证本文所建立的计算系统的适用性和有效性,分别以五层框架结构(带支撑和不带支撑)、桁架结构(平面和空间塔式桁架)和大型浮式海洋结构为模型,通过数值模拟和实验验证了各种滤波算法在结构损伤识别分析中的显著特点。
