ABSTRACT:
A concrete rod-like member having a seismic control structure which utilizes structural features of the rod-like structure efficiently without paying high cost and is capable of protecting a body potion of the rod-like member (including a building carried on piles when the rod-like member is used as the piles) against rupture even when subjected to the level 2 load. A piled ring assembly composed of a plurality of annular plates placed one upon another and tied together in a direction of piling is disposed around the periphery of a longitudinal portion of a body of the concrete rod-like member such that a central axis of the piled ring assembly is coincident with a longitudinal central axis of the rod-like member body. The longitudinal portion of the rod-like member body including the ring assembly forms a frail portion of the rod-like member. The rod-like member may include two or more of the frail portion.
