Punching Shear Capacity of Recycled Aggregate Concrete Slabs
Buildings, 2022 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.

Enhancing punching shear and post-punching behavior of flat slabs using wire mesh, integrity bars and fibers [PDF]
Scientific ReportsPunching shear failure is a common issue in the connection between flat slabs and reinforced concrete columns. Once failure occurs, a supplementary load-carrying mechanism is necessary to prevent the progressive collapse of the connections.

Strength of cast-in-place slabs for rectangular cross-section columns punching [PDF]
E3S Web of Conferences, 2021 Flat slabs in contemporary buildings are most commonly supported by rectangular cross-section columns. Research of slabs supported by rectangular cross-section columns for punching is rather narrow.

Punching Shear Strength of Reinforced Concrete Flat Plates with Openings
Jurnal Engineering, 2023 Test results of six half-scale reinforced concrete flat plates connections with an opening in the vicinity of the column are reported. The test specimens represent a portion of a slab bounded by the lines of contraflexure around the column.
