Abstract:
Based on a practical bridge, the trial design and design checking of integral curved bridge were carried on. The 3D finite element model of the original bridge and the trial-design bridge were built respectively by using MIDAS/Civil2015 software, and the latter one considered the pile-soil interaction and abutment-soil interaction. Then the mechanical performances of original bridge and integral curved bridge were analyzed and compared under dead load, live load(vehicle load), temperature load, concrete shrinkage and seismic load. The results show that the girder end has greater negative bending moments under dead load, live load, temperature load, concrete shrinkage and seismic load because of a fixed connection at the girder end and earth pressures behind abutment. Compared with the original bridge, the girder of the integral curved bridge has a relatively uniform bending moment distribution under dead load, but the effect of live load on bending moments of the girder is similar. The temperature load has a greatest influence on internal forces of girder of the integral curved bridge, and the second is concrete shrinkage, so they should be taken seriously in design. The torques of the girder of the original bridge and integral curved bridge are basically antisymmetric under dead load and live load, and the torques of girder on the end spans of the integral curved bridge are significantly smaller than the ones of the original bridge under dead load, but the torques of girder between the two are not much different under live load, so it can be known that the trial-design curved bridge has a better torsion performance than the original bridge. Besides, the seismic performance of the integral curved bridge is rather better than that of the original bridge, and it can effectively avoid the lateral movement and falling of the girder during earthquake action, so the integral curved bridge can be applied preferably in high seismic zones.
