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).

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 ...

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.
