Strengthening of slab-column connections using ultra high-performance fiber concrete
Case Studies in Construction Materials, 2022 This experimental work intends to assess the efficiency of employing ultra-high-performance fiber concrete (UHPFC) as a strengthening system for improving the punching shear capacity of slab-column connections (SCCs).

Effect of Shear Reinforcement on Punching Shear Capacity of Reinforced Concrete Flat Plates
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Punching or two-way shear is a critical failure mode that must be accounted for in reinforced concrete (RC) slabs that are not supported by beams, known as flat plates. The often gravity-driven failure occurs around supporting columns may also be influenced by lateral forces. This paper presents the findings of a numerical study

Performance of reinforced concrete flat slab strengthened with CFRP for punching shear
Case Studies in Construction Materials, 2023 Existing reinforced concrete (RC) slabs need punching shear reinforcement due to design defects, structural damage, increased loading, corroded reinforcement bars, and change in the use or function of the buildings.

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.

International Journal of Concrete Structures and Materials, 2022 In the construction of concrete bridges, the lighter dead load of decks can significantly reduce the number or size of substructure members, such as girders, piers and foundations. Although, the arch decks (ADs) ensure superior load carrying capacity and

Post punching shear pattern and progressive collapse of flat slab building [PDF]
Revista IBRACON de Estruturas e Materiais, 2023 The possibility of the occurrence of a second punching shear failure and of a Progressive Collapse after a punching shear failure had occurred in one flat slab column connection is investigated in two building structures, using Eberick and SAP2000 ...

Behavior of composite pre-flat slabs in resisting punching shear forces
Alexandria Engineering Journal, 2020 Due to large use of the composite pre-flat slabs “two layers slabs” especially manifested in pre-cast system slabs such as frequently used in bridge dicks, large thickness slabs casted on two layers or change usage of existing structure.

Facta Universitatis. Series: Architecture and Civil Engineering, 2021 The paper first presents the calculation of the punching shear capacity of concentrically loaded reinforced concrete column footings according to the current Eurocode 2, which can be carried out in two ways: by conducting an iterative procedure and by a ...

Effect of premature loading on punching resistance of reinforced concrete flat slabs
Case Studies in Construction Materials, 2020 Premature loading of reinforced concrete flat slabs in multi storey buildings during construction may occur after shuttering removal and loading slabs earlier than usual to meet project time targets.

Investigation of longitudinal reinforcement contribution in shear punching of reinforced concrete flat slabs without transverse reinforcement [PDF]
MATEC Web of Conferences, 2019 The shear punching of the reinforced concrete slabs is a complex process occurring when considerable force is concentrated on the relatively small area of a column-slab connection. An incorrect assessment of load capacity of slab under the punching shear
