DAMAGE IDENTIFICATION OF TRUSSES BY FINITE ELEMENT MODEL UPDATING USING AN ENHANCED LEVENBERG-MARQUARDT ALGORITHM

This paper presents an efficient method for updating the structural finite element model. Model updating is performed through minimizing the difference of recorded acceleration of real damaged structure and hypothetical damaged structure, by updating physical parameters in each phase using iterative process of Levenberg-Marquardt algorithm. This algorithm is based on sensitivity analysis and pr...

Updating finite element model using frequency domain decomposition method and bees algorithm

The following study deals with the updating the finite element model of structures using the operational modal analysis. The updating process uses an evolutionary optimization algorithm, namely bees algorithm which applies instinctive behavior of honeybees for finding food sources. To determine the uncertain updated parameters such as geometry and material properties of the structure, local and...

Finite element model updating of a geared rotor system using particle swarm optimization for condition monitoring

In this paper, condition monitoring of a geared rotor system using finite element (FE) model updating and particle swarm optimization (PSO) method is onsidered. For this purpose, employing experimental data from the geared rotor system, an updated FE model is obtained. The geared rotor system under study consists of two shafts, four bearings, and two gears. To get the experimental data,  iezoel...

Finite element model updating of a truss model using incomplete modal data

This paper presents an application of a two-step finite element model updating methodology to a 3D truss bridge model, with the inertial moment and elastic modulus as variables. First, the sensitivity of the change in modal parameters to variations in the physical parameters were analyzed. Based on these sensitivity analyses, the parameters that can be updated were determined. Next, the optimiz...

Finite Element Model Updating of Scale Bridge Model Using Measured Modal Response Data AUTHORS

One of the most promising fields of finite element model updating involves using data obtained from the modal response of a structure to update a finite element model. The University of Central Florida (UCF) has constructed a scale model of a two span bridge. Using an impact hammer and accelerometers mounted on the structure, the first 17 natural frequencies and mode shapes were identified. Usi...
