And Function

Dynamic load test is to measure the natural vibration characteristics of the bridge structure or the forced vibration characteristics under dynamic load, and to evaluate the driving performance, driving safety and comfort of the bridge through dynamic load test. In order to evaluate the stress state and working performance of a reinforced concrete box-ribbed arch bridge, the load test of the bridge is carried out. Dynamic load test is used to test the inherent fundamental frequency, damping ratio and impact coefficient of the bridge through pulsation test and sports car test. Through the experiment with the key parts of the stress (strain) and displacement load and other important data, through analysis and study, the comprehensive analysis of the phenomenon of calculation and test, a comprehensive performance evaluation structure and function whether meet the design requirements, to provide technical basis for the safety of the bridge operation, and provide the original material for the bridge maintenance and management in the future.

Curved Girder Bridges

Ramp bridges are usually curved girder bridges, and show unique mechanical characteristics under live load. On the basis of an interchange ramp bridge static and dynamic load test in a radius of 230m, the bridges stress, deflection and dynamic characteristics were analyzed and the bearing capacity was evaluated.

The author carried out dynamic load test research on a prestressed concrete rigid frame bridge. Under dynamic load, the ratios of the measured and theoretical frequencies of the first four vertical vibrations of the bridge were 1.081, 1.153 respectively. The corresponding measured damping ratios are 0.011, 0.010 respectively. The maximum dynamic coefficient of bridge sports car test is 1.049, and the corresponding dynamic strain increment coefficient is 0.059. The measured impact coefficient is between 0.012 and 0.049, which is basically equivalent to the design impact coefficient of 0.05.The test results show that the existing bridge works well under the test load, and the bearing capacity of the structure meets the requirements of the design load level.

Reconstruction Project

For an existed reinforced concrete rigid-frame arch bridge in reconstruction project, reinforcement effects of the bridge are studied and discussed while the original load grades are maintaining and it is based on dynamic load test including scheme, execution and FEM analysis in this paper. In our investigations, such characteristics as dynamic flexibility, impact coefficient, natural vibrations and dynamic responses are analyzed. All the investigations show that the bridge meets the original-designed-loading requirement, which behaves well in dynamic characteristics after being strengthened and whose stiffness also satisfies requirement.

In order to evaluate single tower composite girder Cable Bridge actual bearing capacity and working property on design using load, a single-tower composite girder cable-stayed bridge is taken as an example, by means of static load test, dynamic load test, reasonably measures evaluates the single tower composite girder cable-stayed bridge's bearing capacity. The static load test measure static properties of bridge structure (static strain, static deflection, etc.), dynamic load test, measure the dynamic properties of bridge structure (vibration frequency, damping, forced vibration amplitude, impact coefficient, etc.). Results show that the rigidity strength integrity and dynamic characteristics of bridge structure are favorable; the structure’s bearing capacity is favorable.
