Dynamic And Static Load Test And Finite Element Analysis Of Continuous Girder Bridge

First to the dynamic and static load test has carried on the induction summary correlation theory, analysis of field test and test data processing in detail, and introduces the related theory for evaluation of test results.Then in a period of a duplicate of the extension project of line 202 in dalian span continuous bridge as the engineering background, with continuous beams of dynamic and static load test, determination of bridge deflection and strain of the control interface, and the vibration response of bridge structure and the fundamental frequency, at the same time in the finite element analysis of the static load test, using the finite element software Midas/Civil build three-dimensional finite element model of continuous girder bridge, analysis of continuous girder bridge load load, moving load tracking module of Midas/Civil is used to calculate equivalent static load, the load of moving load based on bridge loading static load simulation analysis was carried out on the continuous girder bridge, in the process of analysis, for each across different analysis for each control section under the action of load load deflection deformation and internal force value, thus to make guidance for bridge static test. In dynamic load finite element analysis, using Midas/Civil time history analysis, get the bridge control section time history curve of displacement and internal force, by comparing the results with the dynamic load test, determine the dynamic characteristics of the bridge is in line with the requirements. In the end, the working state of the bridge was evaluated.
