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.

Punching Shear Characterization of Steel Fiber-Reinforced Concrete Flat Slabs
HighTech and Innovation Journal, 2022 Punching shear failure in thin slabs under concentrated loads can cause shear stresses near columns. The use of steel fiber is a practical way to improve a slab-column connection's punching strength and deformation capacity.

Pilot Experimental Tests on Punching Shear Strength of Flat Plates Reinforced with Stirrups Punching Shear Reinforcement [PDF]
Journal of Materials and Engineering Structures, 2017 Flat plates are favor structure systems usually used in parking garages and high-rise buildings due to its simplicity for construction. However, flat plates have some inherent structural problems, due to high shear stress surrounding the supporting ...

Influence of the Distribution and Level of Post-Tensioning Force on the Punching Shear of Flat Slabs
Designs, 2022 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 ...

Performance of reinforced concrete flat slab strengthened with CFRP for punching shear
Case Studies in Construction Materials, 2023 Existing reinforced concrete (RC) slabs need punching shear reinforcement due to design defects, structural damage, increased loading, corroded reinforcement bars, and change in the use or function of the buildings.

A New Punching Shear Equation of Normal and High Strength Reinforced Concrete Flat Slabs
Journal of Engineering and Sustainable Development, 2012 The aims of this study is to present a new simple accurate equation to determine the punching shear strength of normal and high strength reinforced concrete flat slabs. The punching shear strength prediction of the proposed equation is compared with the
