중공PC콘크리트의 두께가 HPC 복합 기둥의 압축강도에 미치는 영향

In this paper Experimental study was performed to evaluate the compressive strength hollw PC column with parameters of hollow size and presence of grout concrete in the hollow. The strength of hollow PC columns without grout concrete decreased due to local failure while the composite column which was filled with grout concrete failed . KCI code comparison with experimental strength was similar as level of 0.95 to 0.99
