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

Shear and punching capacity predictions for slabs under concentrated loads aided by lefea
, 2023 One-way slabs under concentrated loads may fail by one-way shear, punching, flexure or a mixed-mode between them. This study examines the benefits of using Linear Elastic Finite Element Analyses (LEFEA) combined with analytical expressions to predict the

Punching Shear Capacity of Continuous Slabs [PDF]
ACI Structural Journal, 2016 Provisions for punching shear design of reinforced concrete slabs are usually calibrated on the basis of results from tests on isolated specimens that simulate the slab zone within the points of contraflexure around a column. However, the punching behavior of interior slab-column connections in actual continuous slabs without transverse reinforcement ...

Punching shear in prestressed concrete deck slabs: a comprehensive study
, 2023 A large number of bridges in the Netherlands have transversely post tensioned deck slabs cast in-situ between flanges of precast girders and were found to be critical in shear when evaluated by Eurocode 2.

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.

, 2023 In concrete flat plate slab-column joints with drop panels, successive punching shear failures often occur at the slab-drop panel interface and along the column perimeter.

Punching capacity of spread footings using aci 318-19 and the strip model
, 2023 In design, the sectional depth of reinforced concrete spread footings is usually governed by design code provisions for punching shear, which are derived primarily from experiments on slab-column connections.

Punching shear of flat reinforced-concrete s labs under fire conditions [PDF]
, 2016 This thesis examines punching shear response of reinforced-concrete flat slabs under fire conditions. The shear behaviour of concrete in fire is relatively poorly understood compared to its flexural response.

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.
