Transmissibility of High-Strength Concrete Column Loads through Normal-Strength Concrete Slabs

일반 강도 콘크리트 슬래브를 통한 고강도 콘크리트 기둥의 축력 전달

Twelve column specimens were tested in compression, six were slab-column specimens and six were isolated column specimens. The slab column specimens were first tested to punching shear failure before the columns of the specimens were loaded axially. The effects of confinement from the surrounding slab on the axial capacity of the columns was investigated. Other parameters investigated were the placement of fiber-reinforced concrete in the slab and the concentration of flexural reinforcement in the column vicinity.
