Punching shear strength and deformation for FRP-reinforced concrete slabs without shear reinforcements

open access: yesCase Studies in Construction Materials, 2022
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

A Novel Feature Selection Approach Based on Tree Models for Evaluating the Punching Shear Capacity of Steel Fiber-Reinforced Concrete Flat Slabs. [PDF]

open access: yesMaterials (Basel), 2020
When designing flat slabs made of steel fiber-reinforced concrete (SFRC), it is very important to predict their punching shear capacity accurately.

Enhancing punching shear and post-punching behavior of flat slabs using wire mesh, integrity bars and fibers [PDF]

open access: yesScientific Reports
Punching 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 analysis of slab‐column connections [PDF]

open access: yesEngineering Computations, 2013
Purpose – The paper aims to present an experimental testing program regarding reinforced concrete slabs, with and without shear reinforcement, submitted to punching under both symmetric and eccentric loading. Comparisons between numerical simulations and experimental behaviour results are carried on.

Influence of the Distribution and Level of Post-Tensioning Force on the Punching Shear of Flat Slabs

open access: yesDesigns, 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 ...

Strength of footing with punching shear preventers. [PDF]

open access: yesScientificWorldJournal, 2014
The punching shear failure often governs the strength of the footing-to-column connection. The punching shear failure is an undesirable failure mode, since it results in a brittle failure of the footing. In this study, a new method to increase the strength and ductility of the footing was proposed by inserting the punching shear preventers (PSPs) into ...

Shear and Punching Capacity Predictions for One-Way Slabs under Concentrated Loads Considering the Transition between Failure Mechanisms

open access: yesBuildings, 2023
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

Pilot Experimental Tests on Punching Shear Strength of Flat Plates Reinforced with Stirrups Punching Shear Reinforcement [PDF]

open access: yesJournal 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 ...

Improving Punching Shear in Flat Slab by Replacing Punching Shear Reinforcement by Ultrahigh Performance Concrete

open access: yesInternational Journal of Engineering, 2022
Extensive studies have focussed on the issue of the failure of punching shear in flat slabs and ways to strengthen it internally, externally and the importance of this structure (flat slab), and the danger of punching shear failure in the areas of ...
