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 Capacity of Recycled Aggregate Concrete Slabs
Buildings, 2022 This article investigates the punching shear behavior of recycled aggregate concrete (RAC) two-way slabs. Ten 1500 mm × 1500 mm × 100 mm slabs were tested monotonically.

Effect of Shape, Number, and Location of Openings on Punching Shear Capacity of Flat Slabs
Buildings, 2021 Experimental evidence have proved that punching shear capacity of flat slabs deteriorate with the presence of openings located within the critical perimeter around columns.

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

Design Equation for Punching Shear Capacity of SFRC Slabs
International Journal of Concrete Structures and Materials, 2011 In this paper, a design equation for the punching shear capacity of steel fiber reinforced concrete (SFRC) slabs is proposed based on the Japan Society of Civil Engineers (JSCE) standard specifications. Addition of steel fibers into concrete improves mechanical behavior, ductility, and fatigue strength of concrete.

The effect on punching shear failure in centrally loaded ground-supported concrete slabs for different aspects like slab thickness, size and the position of reinforcement bar, and the strength of concrete using a validated FE model [PDF]
HeliyonThe effect of slab thickness, presence of reinforcement and concrete strength on punching shear capacity of the ground-supported concrete slabs (GSCS) is an important issue in Industrial Ground-supported slab construction.

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
