摘要
Abstract
Most system identification methods do not represent thecomplexity and uncertainties one would encounter when dealing with actual engineering problems. The purpose of the present study is to propose an improved damage detection and assessment approach, established on the basis of the method of system identification that can be effectively used in real structural projects. Using Xingfu temple tower as an example, the particularities of damage identification for ancient buildings are discussed in this paper. An approach to determine the baseline system according to the design goal that satisfies the current code requirements is proposed. This paves the way for the possible use of the system identification techniques in cases like ancient building structures for which no data for the undamaged state are available. The measured natural frequencies and modal shapes of Xingfu temple tower are used in the estimation for decrease in stiffness parameters. The application of the distinguish analysis method and the approach to assess the degree of damage under conditional distributions proposed in paper I on the particular ancient tower is found to lead to acceptable results.关键词
