중공사각단면 기둥에 있어서 횡철근과 Cross-tie의 횡방향 구속 효과에 대한 해석적 연구
An Analytical Study on Confinement Effect of Transverse Reinforcement and Cross-Tie in Hollow Rectangular Sectional Columns
초록
This paper presents the confinement effect of transverse reinforcement and cross-tie in hollow rectangular sectional columns. 20 analytical models with different amounts of transverse reinforcement and cross-tie in a plastic hinge region were analyzed by 3D nonlinear FEM. The analytical results show that the higher ductility can be achieved by the resonable combination of transverse re-bar and cross-tie providing sufficient lateral confinement.
