Abstract
In the analysis of large structures, usually finite element model according to the blueprint, the finite element model thus created often fail to reflect the true state of the actual structure. It is necessary to establish the finite element model is corrected. Typically, finite element model updating is defined as a rigidity and quality test results of the analysis of dynamic frequency, mode shape modification theory of finite element model parameters to ensure the accuracy of modal parameters premise itself, so that the vibration parameters finite element model corrected tended test values. After finite element model updating can be applied to structural dynamic response and dynamic security analysis again, some vibration control technology control strategy formulation, structural damage identification, the bridge health monitoring and safety assessment, structural optimization design and the like. This paper evaluates the structural model features required by the state of the bridge structure, modeling methods are given to build large span bridges for structural condition assessment model for the bridge structure such as pylon, deck lines and coupling conditions, etc. Finite element simulation and thus to assess the structural state of the bridge
