Behavior of axially and eccentrically loaded square RC columns retrofitted with steel strips
Case Studies in Construction Materials, 2022 This paper introduces experimental and theoretical research on the compression behavior of reinforced concrete (RC) columns after retrofitting. The axially loaded columns were retrofitted by steel strips, while the eccentrically loaded columns were ...

CONFINEMENT OF RC COLUMNS WITH CFRCM
Proceedings of International Structural Engineering and Construction, 2020 Textile reinforced concrete is becoming increasingly important in construction. Besides the application in new constructions, textile reinforcement can be used for the strengthening of plain and reinforced concrete structures in the form of fabric reinforced cementitious matrices (FRCMs).

Effect of Bond-Slip on Dynamic Response of FRP-Confined RC Columns with Non-Linear Damping
Applied Sciences, 2021 As a composite material, the damping energy consumption mechanism of fiber reinforced polymer-confined reinforced concrete (FRP-C RC) structure is very complex. In previous dynamic calculation models, the bond-slip effect for steel bars was often ignored,

Numerical Investigation of Behavior of RC Columns Strengtheneg with RC Jacket [PDF]
Academic Perspective Procedia, 2019 Strengthening of structural elements which are insufficient in terms of earthquake performance is very important for the safety of existing structures. Nowadays, one of the most commonly used methods is strengthening such members with RC jacketing. Several experimental studies have been conducted in the literature to investigate behavior of structural ...

Numerical Analysis of Retrofitted RC Column under Lateral Load [PDF]
Computational Engineering and Physical Modeling, 2022 One of the most common retrofitting processes for columns is reinforced concrete (RC) jacketing. This process enhances the ductility, stiffness, flexural capacity, and shear capacity of columns, and increases the axial load-carrying capacity of the RC ...
