<p>PROBLEM TO BE SOLVED: To make the function as a plastic hinge of a reinforced concrete stud provided in water hard to be deteriorated.SOLUTION: A core part of a skeleton 2 of a reinforced concrete stud 10 is constituted of a plurality concrete of blocks 21 stacked in the vertical direction. Thus, since the skeleton 2 has a discontinous surface 2a between the concrete block 21 and the concrete block 21, when the skeleton 2 is flexuously deformed by an earthquake or the like, a crack is formed on an extension of the discontinuous surface 2a in concrete 22 of an outer peripheral surface of the skeleton 2, and the crack is hardly caused in the concrete block 21. Since water infiltrated from the crack formed in the concrete 22 of the outer peripheral surface only goes into and out of the discontinuous surface 2a, the skeleton 2 can continuously function as the plastic hinge without progressing the crack to the inside of the concrete block 21.</p> |
