Deformation Capacity of Reinforced Concrete Columns Subjected to Axial Compression and Lateral Load Reversals

축력 및 반복 횡하중을 받는 철근 콘크리트 기둥의 변형능력에 관한 연구

The objective of this experimental investigation is to examine the feasibility and the usefulness of the complementary crosstie in the current ACI 318-89 code for rienforced concrete columns subjected to constant axial load and lateral load reversals. Tests were conducted on1/3 scaled four columns with the length of 1.9m and the cross section of 20$\times$20 cm. The main parameters of specimens were the magnitude of axial load applied and the configuration of transverse reinforcements . From the experimental results, it can be seen that while the column subjected to lower axial load represented considerable ductility behaviors, the column subjected to higher axial load showed the brittle failure
