In recent years, fiber-reinforced polymers have been widely utilized to improve the seismic performance of deficient RC columns. In this study, the flexural behavior of CFRP strengthened rectangular RC columns with plain bars and insufficient confining steel was investigated Five specimens, representing a typical deficient building column with poor transverse reinforcement detailing and low concrete strength, were tested under cyclic displacement excursions and constant axial load. The beneficial effect of CFRP anchor dowels and the FRP confinement ratio on the ultimate drift ratio of the specimens was assessed It was found that an increase in the confinement ratio enabled the column to sustain higher ultimate drift capacities for the strengthened columns Furthermore, an appropriate configuration of CFRP anchor dowels resulted in a better seismic behavior compared to the CFRP retrofitted column without any dowels Subsequently. a simplified drift based design equation was proposed for FRP retrofit design of deficient rectangular columns.

Seismic upgrading of reinforced concrete frames with structural steel elements
Özçelik, Ramazan; Binici, Barış; Department of Civil Engineering (2011)
This thesis examines the seismic internal retrofitting of existing deficient reinforced concrete (RC) structures by using structural steel members. Both experimental and numerical studies were performed. The strengthening methods utilized with the scope of this work are chevron braces, internal steel frames (ISFs), X-braces and column with shear plate. For this purpose, thirteen strengthened and two as built reference one bay one story portal frame specimens having 1/3 scales were tested under constant grav...
Repair and strengthening of reinforced concrete columns with CFRPs
Ozcan, Okan; Binici, Barış; Canbay, Erdem; Ozcebe, Guney (SAGE Publications, 2010-8-17)
In this study, seismic retrofitting of undamaged and moderately damaged RC columns with CFRP was investigated. The experimental program was conducted on five RC columns with inadequate tie spacing, 90-degree hooks at tie ends, and plain (undeformed) reinforcing bars. Columns were tested under a constant axial load of 27% of axial capacity and under reversed lateral cyclic loading. The primary objective of this study was to investigate the influence of sustained axial load during repairing, damage, and corne...
Seismic Retrofit of Deficient RC Structures with Internal Steel Frames
ÖZÇELİK, RAMAZAN; Akpinar, Ugur; Binici, Barış (2011-12-01)
This paper describes an experimental study on internal steel frames (ISFs) to retrofit seismically deficient reinforced concrete (RC) frames. One reference and six strengthened frame specimens were tested under constant gravity load and cyclic lateral displacement excursions. Installation of the ISF with and without anchors to the RC frame was examined. Test results showed that the snug tight ISF installed inside an RC frame may suffice to realize the benefit of implementing ISFs. If the horizontal shear st...
Plastic rotation capacity of RC columns under biaxial seismic demands
Özcan, Okan; Binici, Barış (2023-03-01)
Seismic performance of reinforced concrete (RC) columns should be evaluated considering biaxial demands for a more realistic assessment. However, most of the current seismic assessment regulations stipulate rotation capacity estimations considering only uniaxial bending test database. The effect of seismic demands in one direction may have a detrimental effect in the deformation capacity of the other direction. In the past studies, the influence of biaxial loading patterns/paths/histories, axial load level,...
Analytical study on seismic retrofitting of reinforced concrete buildings using steel braces with shear link
Durucan, Cengizhan; Dicleli, Murat (2010-10-01)
This paper is focused on a proposed seismic retrofitting system (PRS) configured to upgrade the performance of seismically vulnerable reinforced concrete (RC) buildings. The PRS is composed of a rectangular steel housing frame with chevron braces and a yielding shear link connected between the braces and the frame. The retrofitting system is installed within the bays of an RC building frame to enhance the stiffness, strength and ductility of the structure. The PRS and a conventional retrofitting system usin...
