Abstract
The influence of concentrated reinforcement in the immediate column region, the use of high-strength concrete slabs, as well as using puddled fiber-reinforced high-strength concrete in the slab in a region close to the column were investigated. The slab concrete strengths of the specimens were 30, 35, 40, 55, 65, and 90 MPa. The performance of the slab-column specimens tested was investigated, including the punching shear capacity, cracking on the top of the slabs around the columns, and the stiffness of the slab-column connections. Predictions using different code equations are compared to the experimental results obtained from the slab-column connections tested in this study and those tested in other studies. The beneficial effects of using concentrated flexural reinforcement, high-strength concrete and puddled fiber-reinforced high-strength concrete are demonstrated.
