Experimental investigation on shear strengthening with fiber/textile reinforced concrete

Structural Concrete, 2023
The use of textile reinforced concrete (TRC) as a shear strengthening solution for reinforced concrete (RC) structures is a viable and effective strategy.

Enhanced service life of existing infrastructure buildings by use of concrete screw anchors as post-installed shear reinforcement

Acta Polytechnica CTU Proceedings, 2022
In the last decades, traffic on railways and roads has increased significantly in Central Europe. On the other hand, the existing infrastructure mainly origins from the late 1950s to the 1970s.

Study of Shear Strengthening of Reinforced Concrete Beams Using Embedded Bars and CFRP [PDF]

Port Said Engineering Research Journal, 2019
A new technique for shear strengthening of reinforced concrete (RC) elements is the embedded through section (ETS). This technique calls for holes to be drilled through the beam section, and then bars of steel are introduced into these holes, bonded with

Shear Strengthening of Reinforced Concrete Beam Using Wire Mesh–Epoxy Composite

Civil Engineering Journal, 2022
This experimental research aims to study the use of wire mesh–epoxy composite (WMEC) as a shear-strengthening technique for reinforced concrete (RC) beams by focusing on the following parameters: (1) presence of shear reinforcement in the shear span; (2)

Influence of Compressive Strength of Concrete on Shear Strengthening of Reinforced Concrete Beams with Near Surface Mounted Carbon Fiber-Reinforced Polymer

Buildings, 2021
This paper investigates the effect of using near-surface mounted carbon fiber-reinforced polymer (NSM-CFRP) on the shear strengthening of rectangle beams with low strength concrete (f′c = 17 MPa), medium strength concrete (f′c = 32 MPa), and high ...

Experimental Study of the Shear Behavior of RC Beams Strengthened with High-Performance Fiber-Reinforced Concrete

International Journal of Concrete Structures and Materials, 2023
Highlights Shear Strengthening of RC beams by HPFRC plates utilizing two methods. Precast HPFRC plates bonded by epoxy adhesive and anchored. Continuous shear strengthening resulted in high-capacity enhancement and ductility.

Investigations into the Shear Load-Capacity of Strengthened Reinforced Concrete Structures with Carbon-Reinforced Concrete

Buildings, 2023
As part of the experiments, 4-point-bending tests to investigate the shear capacity of strengthened T-beams were carried out. Thereby, 5 reference beams and 25 T-beams with carbon reinforced concrete strengthening were tested.

An experimental investigation for external RC shear wall applications [PDF]

Natural Hazards and Earth System Sciences, 2010
The strength and rigidity of most reinforced concrete (RC) buildings in Turkey, which are frequently hit by destructive earthquakes, is not at a sufficient level. Therefore, the result of earthquakes is a significant loss of life and property.

Anomalous acoustic reflection on a sliding interface or a shear band [PDF]

, 2003
We study the reflection of an acoustic plane wave from a steadily sliding planar interface with velocity strengthening friction or a shear band in a confined granular medium.

Mechanisms for slow strengthening in granular materials [PDF]

, 1999
Several mechanisms cause a granular material to strengthen over time at low applied stress. The strength is determined from the maximum frictional force F_max experienced by a shearing plate in contact with wet or dry granular material after the layer ...
