Punching Shear Capacity of Recycled Aggregate Concrete Slabs
This article investigates the punching shear behavior of recycled aggregate concrete (RAC) two-way slabs. Ten 1500 mm × 1500 mm × 100 mm slabs were tested monotonically.

Columns Cross-Section Shape Effect on Punching Shear in Reinforced Concrete Flat Slabs
Punching shear is one of the possible failures that must be taken into consideration in designing concrete slabs and foundations. Several factors control the occurrence of this failure mechanism, such as slab thickness, concentrated loads, and the cross-

While very little is known about the punching shear behavior of Fiber Reinforced Polymer (FRP)-reinforced concrete slabs; thus, very few design codes for this case are available. Most available design codes and guidelines are missing the physical meaning

Flat Slabs in Eccentric Punching Shear: Experimental Database and Code Analysis
Eccentric punching shear can occur in concrete slab–column connections when the connection is subjected to shear and unbalanced moments. Unbalanced moments occur in all floor slabs at the edge and corner columns.

Influence of the Distribution and Level of Post-Tensioning Force on the Punching Shear of Flat Slabs
Punching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection is always vulnerable to critical punching shear; thus, it is necessary to investigate the effect of various parameters on the ...

Reinforced concrete one-way slabs under concentrated loads can develop different shear failure mechanisms: as wide beams in one-way shear, punching shear around the load or a mixed mode between them. Until now, most publications presented recommendations

Slabs strengthened for punching shear with post-installed steel and CFRP connectors
Structural accidents due to punching shear failures have been reported in flat slab buildings. Design recommendations presented by codes can lead to entirely different punching shear resistance estimates for similar situations.

Derivation of material properties using small punch and shear punch test methods [PDF]
The Small Punch (SP) and Shear Punch (ShP) tests are well established mechanical test approaches that have found application in several industrial sectors for material ranking and mechanical property estimation, particularly where more conventional approaches are inhibited.
