Punching shear capacity of flat slabs with recycled aggregate
World Journal of Engineering, 2022Purpose Punching can trigger catastrophic failures in flat slabs because of its sudden nature resulting from exceeding the shear capacity of slabs. Effect of using recycled aggregate, as an environmental-friendly alternative to traditional RC structures, on punching behavior of these slabs was not sufficiently investigated in the literature.

Effect of Membrane Forces on Punching Shear Capacity of Flat Slabs
Solid State Phenomena, 2021The paper presents the analysis of the membrane forces and moment redistribution effect on punching shear capacity of flat slabs on the area of the inner column. The previous experimental tests performed on the isolated slab specimens representing the slab-column connections are assessed by the method that uses the levels-of-approximation (LoA ...

Residual punching shear capacity of corroded reinforced concrete slabs
Magazine of Concrete Research, 2023Steel reinforcement corrosion is becoming a critical issue due to the amount of old buildings still in operation with a high probability of substantial corrosion in their reinforcements. The strength and serviceability of corroded reinforced concrete (RC) slab is remarkably impacted by corrosion.

Recycled aggregate concrete slab punching shear capacity
Structures, 2020Abstract Punching shear strength of balanced slab-column connections made of two grades of Recycled Aggregate Concrete (RAC) with each grade containing selected volumetric replacement levels (0%, 50% and 100%) of recycled concrete aggregates derived from laboratory waste concrete are reported.

Punching Shear Capacity of Lightweight Aggregate Concrete Flat Slabs without Shear Reinforcements
Magazine of Concrete Research, 2022This study examined the effect of the unit weight and compressive strength of concrete on the punching shear capacity of flat slabs without shear reinforcements. The slabs were prepared using all-lightweight aggregate concrete (ALWAC), sand-lightweight aggregate concrete (SLWAC), and normal-weight concrete (NWC) at the different compressive strengths ...

Punching shear capacity of steel-fibre recycled aggregate concrete slab
Magazine of Concrete Research, 2022For this paper, the punching shear behaviour of 18 steel-fibre recycled aggregate concrete (SFRAC) balanced slab–column connections was experimentally investigated and analytically modelled for the following variables: the recycled concrete aggregate replacement level (0, 50 and 100%) and the volume fraction of hooked-end fibres (0, 0.4 and 0.8%). The

Punching shear capacity of RC slab-CFT column connections
Engineering Structures, 2020Abstract This study experimentally investigates punching shear capacities of composite slab-column connections consisting of reinforced concrete (RC) flat slab and concrete-filled steel tube (CFT) column. A total of six specimens were tested under monotonically-increased load.
