Slab punching shear
WebMay 1, 2024 · The effects of flexural reinforcement and shear reinforcement on the punching shear strength of slab–column connections are analyzed in this study. For the study, six slab–column connection specimens were constructed with varying flexural reinforcement and shear reinforcement, and were subjected to gravity load tests. …
