โฆ Synopsis
The authors propose the use of generic elements as a viable tool for parametric model based damage detection. The subject is divided into two related papers, and this paper is concerned with the requirements of the baseline model for damage detection, and the use of model updating to produce a validated finite element model of the undamaged structure. Two parameterisations are considered, based on the need to use the same parameterisation for subsequent damage detection. The novel aspect of this approach is the use of generic elements in damage detection where a preliminary updating exercise is required. The result is an updated model with physical meaning that may be used to detect and locate damage in a symmetric structure.

Finite element model updating has become an important topic in structural dynamic applications. It leads to either correction of errors in the model or damage detection and evaluation in a structure. This paper is concerned with the second application using the sensitivity-based updating approach. A
A two-stage eigensensitivity-based finite element (FE) model updating procedure is developed for structural parameter identification and damage detection for the IASC-ASCE structural health monitoring benchmark steel structure on the basis of ambient vibration measurements. In the first stage, both
