Response Analysis of Bridge across Seismic Fault Zone

Abstract:

Through simulating the happening location of the fault zone, the structure model is duly simplified, analysing the forced deformation law of the bridge surface with different fault zone position. Because of statically indeterminate structure, continuous beam shall be produced larger additional moment, shear force and torque as a result of displacement in bridge pier, additional stress will be increased with the the increasement of fault zone displacement, especially for the top surface parts of bridge pier. Hence, the corresponding position of the structure and construction measures for reinforcement should strengthened, the overall rigidity of the structure should be improved, and based on the study of the bridge across the fault zone is a simplified, and the actual stress process may be more complex, the investigation on geological condition must be clear, and avoid the bridge structure crossing fault zone.
