Abstract

The punching shear behavior of slabs reinforced with high-strength steel reinforcement was studied and compared with that of slabs reinforced with conventional steel reinforcement. The high-strength steel selected for this research conforms to ASTM A1035-07. The influences of the flexural reinforcement ratio, concentrating the reinforcement in the immediate column region, and using steel fiber-reinforced concrete (SFRC) in the slab on the punching shear resistance, post-cracking stiffness, strain distribution, and crack control were investigated. In addition, the test results were compared with the predictions using various design codes. The use of high-strength steel reinforcement and SFRC increased the punching shear strength of slabs, and concentrating the top mat of flexural reinforcement showed beneficial effects on post-cracking stiffness, strain distribution, and crack control.
