Slabs punching shear capacity for normal strength concrete (NSC) and high has been investigated in this paper. Due to the significance of technology construction industry, more attention paid Then, detailed comparison is carried evaluate outcome by referring several existing standards. tests have collected from reported results literature. Forty-seven tested slab specimens grouped available pub...

Punching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection always vulnerable to critical punching shear; thus, it necessary investigate effect various parameters behavior flat slabs. This work presents an experimental study evaluate level prestressing force and layout strands in terms maximum load, deflection, stiffness, ducti...

This paper utilises non-linear finite-element analysis with three-dimensional (3D) solid elements to gain insight into the role of shear reinforcement in increasing punching resistance at internal columns flat slabs. The element correctly captures experimentally observed gradual decrease concrete contribution slab rotation and failure mode but is very computationally demanding. As an alternativ...
