An Experimental Study on the Inelastic Behavior of the Reinforced Concrete Column Subject to Cyclic Lateral Loads

반복수평하중을 받는 철근콘크리트 기둥의 비탄성 거동에 관한 실험적 연구

This research has been carried out experimently to verify the structural efficiency of the reinforced concrete columns subjected to cyclic lateral loadings in the inelastic range. Sixteen specimens have been used in the tests, the factors such as reinforcing bars, shear-span ratio, axial load level and loading history being taken differently. The load-carrying capacities and the stiffness degradation in the inelastic range by cycle lateral load application have been counted by observing the load-deformation relationship, the crack initiation and propagation and the energy dissipation phenomena.
