Abstract: This paper reviews stochastic system identification methods that have been used to estimate the modal parameters of vibrating structures in operational conditions. It is found that many classical ...

Abstract: The change of modal characteristics directly provides an indication of structural damage. Based on changes in frequencies and mode shapes of vibration, a damage identification technique is proposed in this paper for ...

Abstract: Most of the mode-based damage identification techniques have been well verified by numerical simulations. However, many of them still face problems when applied to real measurements where noise is present. In this paper, ...

Abstract: In the domain of civil engineering it is often necessary to monitor constructions such as buildings or bridges to maintain safety conditions. Nondestructive test methods outmatch other methods, because they do not influence ...

Abstract: Vibration testing is a well-known practice for damage identification of civil engineering structures. The real modal parameters of a structure can be determined from the data obtained by tests using system identification ...

Abstract: Different methods are proposed in literature using experimental modal information to detect possible damage. In this paper a finite-element (FE) model updating technique is applied. The unknown properties of a FE model are ...

Abstract: To investigate monitoring of concrete members by integrating fiber optic technology, a series of static and dynamic loading tests have been conducted on a posttensioned concrete girder with a span of

Abstract: This article presents an evaluation of the dynamic behavior of a slender steel footbridge before and after the installation of two tuned mass dampers (TMDs). The results of the experimental study show that the damping ...
