Investigation of Dynamic Load Test of an Existed Reinforced Concrete Rigid-Frame Arch Bridge

Abstract:

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.
