Parameter Estimation of FE Model of a Bridge Using Identification System Assisted by Paris Software

Abstract:

Recent studies in the field of Structural Health Monitoring SHM using nondestructive test NDT have shown promising applications for parameter estimation methods based on finite element FE models of bridge structures. Using measurements data, carried out during the experiment on real bridge structures, in situ, one can estimate the structural parameters of the bridge. These parameters can be used further in the process of model updating, model verification, structural evaluation and damage assessment. This paper aims to determine the structural parameters using the PARIS approach from a simulated FE model of a real bridge structure subjected to a typical bridge damage scenario. The MATLAB computer based program, entitled PARIS PARmeter Identification System used for the study case illustrated in this paper is applied for the Finite Element FE model updating of a reinforced concrete bridge, located in Iași municipality. PARIS software takes advantage of the Application Programming Interface API of a standalone structural computing software allowing to perform the necessary computational steps for the model updating process. In the same time the application of this software, recently developed by Prof. Masoud Sanayei permits the use of static and modal measurements, as input data, for the estimation of stiffness and mass parameters at the element level of the bridge. The obtained results of the updated model are useful in the process of further validation of a simulated damage test data. Finally, the results based on FE model parameter estimation can be useful for the structural health monitoring and condition assessment process of the bridge structure.
