劣化や補修を施した単配筋RCアーチ構造の衝撃振動試験による固有振動数評価

抄録

This paper attempted to understand the vibration performance of RC arches under various conditions by impact vibration tests. In addition, we derived an evaluation formula for the vibration performance of arch structures. As a result, it was shown that it is possible to evaluate the natural frequencies of RC arches with deterioration or repair. Furthermore, specimen with many cracks tended to have lower natural frequencies and higher damping coefficients than that without cracks. And it was confirmed that the natural frequencies tend to be high and the damping coefficients tend to be small by the inside pressure hardening method.
