چکیده مقاله
In this paper, using the Finite Element Model Updating FEMU of a steelcantilever beam, the support conditions of a partially fixed connection and thebehavior of the beam are investigated The FEMU, as an appropriate techniquefor Structural Health Monitoring SHM , has been utilized in the past based ondata extracted from discrete sensors In this research, the information related todisplacement and strain is continuously measured on the beam surface using theDigital Image Correlation DIC method The difference between the initialmodel and the DIC measurements is determined by a cost function A hybridmethod called Powell Particle Swarm Optimization PPSO is used to minimizethe cost function This method includes Particle Swarm Optimization PSO asa global search technique and Powell optimization as a local search technique A dynamic inertia weight is presented to improve the performance of the PSOalgorithm Finally, the dependency of beam behavior on each of the variables isinvestigated This method yields acceptable convergence of the results and canbe extended to study other structural components
