Parametric Study on Seismic Performance of Internally Confined Hollow CFT Column
내부 구속 중공 CFT 교각의 내진성능에 대한 매개변수 연구
Abstract
Internally Confined Hollow-Concrete Filled Tube(ICH-CFT) column which has two tubes on both side of concrete, inner tube and outer tube perform great seismic abilities, ductility and absorption of energy, by the tubes and the hollow part. So this study does qualitative analysis about seismic capacities depending on parameters - diameter of column, hollow ratio, thickness of tubes - by moment-curvature analysis.
