Abstract
In this study, the structural performance of high strength concrete (HSC) column-normal strength concrete (NSC) slab connection was investigated according to confinement effects, aspect ratio (h/c) and strength ratio ($f^{\prime}_{cc}/f_{cs}$). The study was conducted by using finite element analysis. To verify the analysis methods, the experiments and analyses results were compared. The specimens were classified by connection types including interior column, edge column, corner column and isolated column. As a result, ultimate strength of interior column was larger than other specimens. Also, the axial stresses of connection were decreased when the aspect ratio was increased. As the strength ratio between column and slab was increased, the ultimate strength of specimens was also increased until the strength ratio was reached to 1.83.
