土木工程系统辨识统计方法的现状分析

An Analysis of Statistical Method of System Identification on Civil Engineering

随着经济的发展以及社会需求的提升,我国的土木工程在迅速的增加,但是土木工程材料具有离散性,并且结构体系比较复杂,受外界环境干扰较大,因此有必要运用统计方法对其进行相应的分析,包括健康监测和损伤辨识等。本文阐述了土木工程系统辨识的概念,然后总结了目前土木工程系统辨识中存在的问题,并简要的分析了一些系统辨识方法以及理论基础,旨在为相关工程人员提供参考意见。

With the development of economy and the increase of social demand, China＇s civil engineering has gained rapid development. However, the civil engineering materials are discreteness, and the structural system is complex and easy to be disturbed by the external environment. Therefore, it is necessary to use statistical methods to analyze them, including health monitoring and damage identification. This paper describes the concept of civil engineering system identification, and then summarizes the existing problems in the civil engineering system identification, and briefly analyzes some system identification methods and theoretical basis, so as to provide reference for the relevant engineering researchers.
