Strength of footing with punching shear preventers. [PDF]

ScientificWorldJournal, 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 ...

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

Scientific 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.

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 ...

Code-based refinement and finite element validation of punching shear design for reinforced concrete footings [PDF]

Scientific Reports
Punching shear failure of reinforced concrete (RC) footings is strongly influenced by soil–structure interaction; however, current design codes evaluate footing punching capacity using slab-based empirical formulations.

Code provisions evaluation for the punching shear capacity of R.C footings without reinforcement for punching shear

Case Studies in Construction Materials, 2023
Il n'y a pas d'accord sur la façon de prédire le cisaillement de perforation pour les semelles entre les différents codes de conception, ce qui est incompatible avec la capacité observée expérimentalement. Une telle incohérence est due aux problèmes suivants : (1) les différentes définitions utilisées par les codes de conception pour la section ...

Punching shear strength of steel fibre reinforced lightweight concrete slabs. [PDF]

, 1981
One of the problems in slab-column connections is the punching shear failure at over loads. Such failures are sudden and catastrophic, and are undesirable since they do not allow an overall yield mechanism to ...

Meniscal shear stress for punching.

Journal of applied biomaterials & biomechanics : JABB, 2009
Experimental determination of the shear stress for punching meniscal tissue.Meniscectomy (surgical treatment of a lesion of one of the menisci) is the most frequently performed arthroscopic procedure. The performance of a meniscectomy is not optimal with the currently available instruments.

Punching shear performance of star-shaped steel plates reinforced RC slab-column connections

Case Studies in Construction Materials, 2023
The progressive collapse of flat plate structures due to brittle punching shear failure of reinforced concrete (RC) slab-column connections is a major concern in structural engineering.

Experimental investigation of punching shear behaviour of ultra-high performance self-compacting concrete slabs

Case Studies in Construction Materials, 2023
The use of heavy reinforced and thick transfer-slab in multipurpose tall buildings is crucial to dealing with many issues such as high bending and punching shear stresses created from relocation of columns in floors above transfer-slab.

The calibration of NLFE model for the assessment of the maximum punching capacity of flat slabs [PDF]

MATEC Web of Conferences, 2023
The requirements on structural engineers to design more subtle flat slabs are still increasing and therefore they must often design a large amount of reinforcement against punching. The maximum amount of transverse reinforcement is limited by the maximum
