Flat slabs can be supported by a column capital or a drop panel in order to provide a good resistance to punching shear around the column. The punching shear capacity of a slab without shear reinfor...
Punching shear failure criterion considering material dynamic effects is proposed. • Shear demand and strength models applied to slabs with/out shear reinforcement. • Enhanced initial slab stiffness governed by inertial rather than strain-rate effects. Abstract Reinforced concrete flat slab structures...

In this way, a punching cone is developed. To improve the punching resistance of the slab, specific shear reinforcement can be provided within the critical perimeter to resist these developed shear stresses. This paper deals with the effect of fire on the punching resistance of concrete thin ...
(xandyaxes of slab plan) and then mounting the external bars (sticking) in one direction and FRP in EBROG (externally bonded reinforcement on groove) method in another direction. The results showed the great efficiency of the method so that the punching shear capacity of strengthened samples ...
This preliminary study investigates the punching-shear behaviour of flat slabs reinforced in flexure and shear with FRP reinforcement. Three full-scale interior slab-column connections were constructed and tested under concentric loading until failure. The three specimens were reinforced in flexure with gl...

This study aims to investigate the use of lightweight aggregate concrete (LWAC) with the bubble deck technology in flat slab. The behavior of two- way LWAC voided slab (with and without shear reinforcement) under punching shear effect with respect to solid normal weight and solid LWAC ...
