Columns Cross-Section Shape Effect on Punching Shear in Reinforced Concrete Flat Slabs
Journal of Techniques, 2023 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-

Eurasian Journal of Science and Engineering, 2023 The system of the flat slab is widely used for the construction of structures because it has economic and functional advantages. However, a flat slab has some disadvantages as punching shear problem occurs by shear force concentrations around the column,

Case 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

Flat Slabs in Eccentric Punching Shear: Experimental Database and Code Analysis
Buildings, 2022 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.

Case Studies in Construction Materials, 2022 Punching shear behavior is experimentally investigated through testing a total of thirteen reinforced concrete flat slabs. Four different types of punching shear reinforcement configurations are examined, namely, ordinary closed rectangular stirrups (ST ...

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 ...

Buildings, 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

Slabs strengthened for punching shear with post-installed steel and CFRP connectors
Revista IBRACON de Estruturas e Materiais, 2019 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]
Materials & Design, 2021 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.

Resisting punching shear stress in reinforced concrete slabs
MATEC Web of Conferences, 2018 Punching shear failure is a major problem encountered in the design of reinforced concrete flat slabs. The utilization of shear reinforcement via shear studs or other means has become a choice for improving the punching shear capacity.
