摘要

The detection of the change of features or damage in large structural system, such as buildings and bridges, can improve safety and reduce maintenance costs. Therefore, feature extract and damage detection from vibration of structures play an important role in operational modal analysis. The objective of this paper is to develop on-line system parameter estimation and damage detection technique from the response measurements through using both the Stochastic Subspace identification (SSI) and Recursive Stochastic Subspace identification (RSSI) approaches. To avoid time-consumption of SVD in RSSI the Extended Instrumental Variable version of Projection Approximation Subspace Tracking is used (EIV-PAST). From numerical study the reliable control parameters of SSI and RSSI methods are examined. Discussion on the pre-processing of data using singular spectrum analysis technique (SSA) is also presented to remove the noise contaminant measurements so as to enhance the stability of data analysis. Finally, the recursive SSA-SSI-COV method is examined to identify the system dynamic characteristics with time-varying model parameters.
