Updating of finite element model of structural vibration for high-piled wharf based on optimization design principle

The high-piled wharf is one of the most widely applied structure of wharf building.Structural vibration of the finite element model is updated by use of physical model test results of piled wharf in this paper.The finite element model is updated based on the restriction optimization theory for the sensitivity analysis of the structure characteristics.The dynamic characteristics of the updated finite element model are closer to the measured value,ideal for dynamic response analysis of damage detecting and for evaluation of high pile wharf structure.
