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: This paper describes different dynamic tests carried out on three bridges, B14, B15, and B13, over highway E19, which connects Brussels and Antwerpen in Belgium. Different excitation types are considered: a drop weight, a ...

Abstract: This paper deals with the dynamic analysis of multispan simply supported railway viaducts subjected to moving trains. In the analysis, the Sesia viaduct is considered, which is a composite railway bridge consisting of seven ...

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 ...
