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 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.

Case Studies in Construction Materials, 2023 There is no agreement on how to predict punching shear for footings among different design codes, which is inconsistent with experimentally observed capacity. Such inconsistency is due to the following issues: (1) the different definitions used by design

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.

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

Punching Shear Strength of Voided Slab: Literature Review and Evaluation of Design Codes
Wasit Journal of Engineering Sciences, 2022 Despite of the economic advantages provided by the voided slabs, their design against punching shear failure, as suggested by the current building codes, are based on the equations derived from tests on flat slabs.

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,

Recommendations to assess the shear and punching capacity of one-way slabs under concentrated loads according to the ABNT NBR 6118:2014 [PDF]
Revista IBRACON de Estruturas e Materiais, 2023 This study describes a set of recommendations to improve the precision of shear and punching shear capacity predictions for one-way slabs under concentrated loads, regardless of the governing failure mechanism, using the ABNT NBR 6118:2014 code ...
