Deformation Capacity under Earthquake on Reinforced Concrete Column Reinforced by Inside Spiral Reinforcement

Abstract

We usually design the reinforced concrete viaduct for railway so that the viaduct has hight defomation capacity to resist big earthquake. So we have studied the reinforced concrete column reinforced by inside spiral reinforcement. But we have not studied fully the deformation capacity of this column. So we studied the deformation capacity and estimation method of this column by reversal cyclic loading test. In this paper, we mainly report on the deformation capacity and propose the estimation method of this column by the results of revesal cyclic loading test.
