Study on Detection Method of Bridge Structure Based on Quasi-Static Test

Abstract:

Currently the bridge structure detections are mainly based on static load test and dynamic load test. The static load test has shortcomings of less test data, long time-consumption and high cost. However, the dynamic load test has the advantages of quick and convenient, its related technologies and theories are still not mature enough. To solve this problem, the detection of bridge structure based on quasi-static test is proposed in this paper. Quasi-static load is applied on the structure by moving the standard load vehicle slowly. Then create the structural finite element model and modify the model according to the measured data to make it consistent with the actual structure. The bridge actual structural mechanical properties can be acquired by conducting load test on the optimized structural finite element model. By doing this, the bridge safety could be evaluated quickly.
