편심축압력을 받는 고강도 콘크리트 충전 각형강관 기둥의 내력에 관한 연구 ( The Column Strength of Eccentrically Compressed Square Hollow section Filled with High Strength Concrete )

Experimental studies on the column strength of eccentrically compressed square hollow section filled with high-strength concrete are presented in this paper. The existence of filled-concrete, specimen length-section depth ratio(L /D=4, 8, 12, 18, 24, 30) and magnitude of eccentricity(e=0.0cm, 2.08cm, 6.25cm, 10.40cm) are taken as the main parameters. The objectives of this paper are to examine maximum load and the effects of high strength concrete, and to compare high strength concrete-filled case with normal concrete-filled case.
