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 ...

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 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.

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

Briefing: Design punching shear capacity of wood-based panels
Proceedings of the Institution of Civil Engineers - Construction Materials, 2014Punching shear capacity is one of the mechanical properties needed in the traditional design calculation method for assessing the concentrated load capacity of wood-based panels. A method for calculating the punching shear capacity of oriented strand board from its planar shear strengths has recently been proposed.

Mechanical model for punching shear capacity of rectangular slab‐column connections
Structural Concrete, 2018This paper investigates the punching behavior of reinforced concrete flat slabs supported on rectangular columns under concentric loading. Based on the critical shear crack theory, a new model is proposed to determine the punching shear strength of slabs. In this model, a rectangular slab is replaced with an elliptical surface with the same area.

In the last years the knowledge of the punching failure in R/C slabs increased thanks to several scientific studies. The progress obtained in this field is considerable, nevertheless achieved results are only taken into consideration by few Codes. The most updated code is the Model Code 2010, which adopted the Critical Shear Crack Theory (CSCT) for the
