An on-site static load test of a reinforced concrete double-arch bridge with fracture is carried out, and a comparative analysis of the measured experimental results of the bridge working conditions and the calculation results of Midas/civil Finite Element Model is performed. The results show that the performance and structural deformation recoverability of the bridge is weak. The bridges overall load-bearing capacity does not satisfy its designed requirements.

This study focuses on test loading program and evaluation for pedestrian bridge. On the basis of the finite element analysis, numerical model of Lv River Bridge, which is a steel box pedestrian suspension bridge, is established. Moreover, field static load test is done and the results of tests are compared to the theoretical values. Results show that the measured result fits well with the theoretical result and bridge is in the situation of elastic deformation, and the strength and stiffness satisfy the need of design.

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.

Through the measured simply supported bridge's dynamic parameters, we can establish the finite element model of the structure.As the flexibility matrix can reflect the actual state of the bridge, making the actual measured flexibility matrix as a basis to inverse the bridge’s finite element model .Combined with the engineering practice static load test, we can assess the bearing capacity of the bridge according to inversion model bridge.

In order to understand the form of deformation and stress characteristics of the integral abutment bridge structures under the loads, this paper bases on Fuyu industrial park crossing bridge, through test vehicle load simulating design load, does a static load test for the bridge, and with the aid of theoretical method to simulate the interaction of pile and soil, builds finite element model, compares between measured and theoretical values of deflection and stress, gets that, the bridge bearing capacity and stiffness is bigger, with sufficient safety reserves.
