Curved rigid-frame bridges at interchanges and junctions play important roles in urban highway networks. However due to complexity of their geometrical configuration and nonlinearities, the seismic behaviour of these bridges are complex and not well-known. This study numerically examines the seismic behaviour of the Ohashi Junction connection viaduct, which is a two-layer rigid-frame curved bridge with large curvatures. A three dimensional nonlinear frame model is constructed based on the design and calibrated in terms of its dynamic characteristics. Dynamic analysis of the model is then conducted to clarify the response dependency on the input direction, effect of pounding, and safety of non-structural components. |
