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 reinforc...
At ultimate limit state, flat slabs are governed by their punching resistance at the slab-column connections, where high bending moments and shear forces develop. This aspect, together with the control of deflections at serviceability limit state, determine the thickness of the slab, ruling the eco...

it is decreased with a sharp drop which indicates the rupture caused by punching shear in the slab. In the specimens S1 and S2 (specimens strengthened by bar inside the groove by EBRIG method)
Underground parking structures often consist of flat slabs connected by columns, for which punching shear is often the most critical design criterion. In fire conditions, the punching load can increase due to restraint of the thermal curvature of the slab or due to the expansion of the columns....
In the calculation of reinforced concrete (RC) flat slabs with transverse reinforcement, punching shear resistance is one of the most critical factors. It is true that design provisions may be implemented, but they often result in significant biases and
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...
Five of specimens were strengthened using steel angles (steel collars) that fixed at the slab-column connection region with different thickness (4, 5, 6, 8, 10) mm and equal legs (75×75) mm to investigate the effects of steel collars on the punching shear resistance with respect to the...
Shear mechanisms govern behaviour of RC flat slabs subjected to impact loading. • Two-phase model developed to predict response of slab subjected to impact loading. • Punching shear failure criterion considering material dynamic effects is proposed. • Shear demand and strength models applied to...
