RC플랫 플레이트 슬래브의 뚫림전단성능에 관한 실험적 연구

Abstract

The primary purpose of this study is to investigate punching shear capacity of flat plate slab using high strength concrete in column. It may be much contributed to economy efficiency and structural advantages that High Strength Concrete used for vertical member and Normal Strength Concrete for horizontal member. Therefore, Six flat slab specimens with HSC column and NSC slab had been made and tested with real scale. The major variables were compressive strength of concrete(fck = 240, 500kgf/cm2), extended length from column face ℓd = 0, d/2, 2d. 60cm) and amount of shear reinforcements. As the result of this test, the following conclusions are shown that the maximum load and behavior of specimens is affected by extended length and shear reinforcements.
