Performance Evaluation of Continuous Box-girder Bridge Structural Properties Based on the Static Finite Element Model Updating

摘要

This paper represents performance evaluation of the structural properties of five-span continuous box girder bridge of a variable cross-section highway, by using static load test results, based on static structural finite element model updating methods. This report expatiates the application procedure, namely, bridge static load test, structural finite element modeling, finite element model parameter updating, performance evolutions. Updated finite element model (parameters) of the bridge structure and the structural properties performance evolution results could be used for damage identification of bridge structures, maintenance, reinforcement and some further structure analytical work.
