Research on Static and Dynamic Model Updating Method Based on Field Test Data

In order to make the bridge finite element model more accurately and effectively reflect state of real bridge, this paper uses dynamic response on-site structural vibration frequency static load strain, proposes a method combining forces construct objective function for optimal analysis. The approach structure Yihe Super Bridge has been corrected. By using “ANOVA” find out significant parameters, then according actual situation project, elastic modulus concrete, thickness deck pavement, concrete bulk density moment inertia beam section are selected as parameters be corrected structure.
