ヒンジ式プレキャストアーチカルバートの正負交番載荷実験による耐震性能評価

抄録

In this study, it is a purpose to elucidate the seismic performance evaluation of 2-hinged precast arch culvert and 3-hinged precast arch culvert. In order to elucidate the seismic performance evaluation for structure, a confirmation of the damage process before reaching the ultimate condition and ultimate condition of the structure is necessary. To confirm the seismic performance evaluation of each arch culvert, the quasi-static cyclic test using the specimen were carried out.As a result, a damage process and a damage part by the cyclic load were elucidated, and it was confirmed that 2-hinged precast arch culvert and 3-hinged precast arch culvert were not collapsed such as the hinge falling off at the ultimate condition.
