Effect of mid-thickness rebar mesh on the behavior and punching shear strength of interior slab–column connection

open access: yesHBRC Journal, 2016
Punching shear failure is a major problem encountered in the design of reinforced concrete flat plates. The utilization of shear reinforcement via shear studs or other means has become a choice for improving the punching shear capacity.

Punching strength of flat slabs with and without shear reinforcement

open access: yesGrađevinar, 2015
The punching shear strength is an extremely significant parameter for the design of flat slabs, i.e. the slabs supported directly on columns, without beams between columns.

Enhancement of punching shear strength of flat slabs using shear-band reinforcement

open access: yesHBRC Journal, 2018
Flat-slab system is widely used nowadays. Major and critical problem of this system is its sudden brittle failure is called punching shear failure. To overcome the punching failure problem, there are many ways to increase the punching shear strength of ...

Experimental investigation of strengthening slab-column connections with CFRP fan

open access: yesAin Shams Engineering Journal, 2019
This paper investigates experimentally the punching shear behavior of flat slabs-column connections strengthened with CFRP (Carbon fiber reinforced polymer) string having a fan shape as a new strengthening technique.

Behavior of composite pre-flat slabs in resisting punching shear forces

open access: yesAlexandria 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.

Post-Punching Mechanisms of Slab-Column Joints Under Upward and Downward Punching Actions

open access: yes, 2021
Progressive collapse of reinforced concrete flat plate systems can be significantly influenced by the post-punching performance of their slab–column joints under large deformations.

Punching shear strengthening of flat slabs: CFRP and shear reinforcement [PDF]

open access: yes, 2015
Punching in slabs is usually associated to the application of concentrated loads or to the presence of columns. One of the main concerns related to flat slabs is its punching shear capacity at slabcolumn connection, which is subjected to a very complex

Experimental Study on Punching Shear Behavior of Ultra-High-Performance Concrete (UHPC) Slabs

open access: yesBuildings
This study assesses the punching shear characteristics of ultra-high-performance concrete (UHPC) slabs in two phases. The initial phase involved experimental tests to determine the critical thickness differentiating punching shear failure and flexural ...

Punching shear in concrete reinforced flat slabs with steel fibers and shear reinforcement

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
Steel fibers in reinforced concrete increase the performance of slab-column connection once they increase ductility and energy absorption capacity of the concrete. The use of fibers in flat slabs may increase strength and change the mode of failure.
