It was found that exposure of slabs to fire resulted in a reduction of up to 18.3% and 43% in cracking loads and ultimate punching loads, respectively. Concrete cover was proven to have a significant effect on level of temperature in tension reinforcement. A reduction in punching strength of...
The test results showed the increases in global punching shear resistance up to 82% and structural rigidity by a thin layer of UHPFRC over the reinforced concrete (RC) substrates. Furthermore, the cracking patterns in the composite systems by two failure modes control the ultimate strength: 1) ...

The design of flat slabs is often compromised by their ability to resist punching shear stresses at slab-column connections. Deterioration of concrete structures due to corrosion of steel limits the service-life and increases the rehabilitation costs and may lead to substantial damages and catastrophic...
In order to study the mechanical behavior of steel fiber reinforced high s trength concrete slab subjected to punching shear,18slab-column connections were tested.The volume of steel fiber in the concrete slabs varie d from 0to2%.The deflection,ductility,energy absorption and bearing capacity o ...
