Abstract: | In the method of earthquake reinforcement on the girder bridge, there are reinforced concrete lining method and steel sheet lining method of bending proof stress control type and reinforced concrete lining method using together with steel sheet. If the girder bridge is reinforced using these construction methods, the toughness of a pier stud section in the girder bridge improves, and a proof stress of it improves, too. However, the load that the pier foundation should bear increases. In this paper, we clarify it about earthquake resistance performance of the girder bridge reinforced in pipe arches. At first, we compare a vibration characteristic found by eigenvalue analysis with a vibration characteristic provided from a vibration experiment. At second, we examine the influence that the pipe arches reinforcement gives to earthquake resistance performance from a result provided by non-linear earthquake response analysis. |
