Investigation of the effect of using geogrid, short glass, and steel fiber on the flexural failure of concrete beams

Alexandria Engineering Journal, 2023
This research studies the flexural behavior of concrete beams reinforced with biaxial geogrids, distributed short glass and steel fibers. No longitudinal steel reinforcement bars were used. Therefore, an amount of short glass and steel fibers was used to

CRACKS IN REINFORCED CONCRETE BEAM

BALANGA: Jurnal Pendidikan Teknologi dan Kejuruan, 2022
Cracks in concrete cannot be prevented but the size of the cracks can be controlled. Cracks that occur in concrete are strongly influenced by the nature and characteristics of the concrete constituent materials, especially cement and water. Cracks can occur in the fresh and hard concrete phases.

The Behavior of RC Beams Strengthened with Steel Fiber Concrete Layer by ANSYS Simulation

Advances in Civil Engineering, 2023
In this study, a double-layer reinforced concrete beam structure was created for the purpose of repairing reinforced concrete beams by pouring a layer of concrete on top of the reinforced concrete beam and then adding fibers to the concrete.

Investigation of Strengthening Reinforced Concrete Beam-Column Connection Wrapped with Fiber-reinforced Polymer

Journal of Studies in Science and Engineering, 2022
In reinforced concrete structures, the beam-column connection area has a considerable influence on the behavior of the structure. The use of fiber-reinforced polymer FRP to strengthen the connections in the Reinforced structure can be one of the ...

Exterior reinforced concrete beam column joint subjected to monotonic loading

Alexandria Engineering Journal, 2018
The joints between beams and columns are crucial zones in a reinforced concrete moment resisting frame. The behaviour of such joints greatly influences the strength and ductility of the overall frame.

Test and Analysis of Concrete Beams Reinforced by Polyurethane Concrete–Prestressed Steel Wires (PUC–PSWs)

Buildings
In order to solve the problems of low tensile strength of composite mortar prone to cracking when reinforced concrete beams are strengthened by traditional methods, this paper proposes a new polyurethane concrete–prestressing wire (PUC–PSW) reinforcement
