Özet
ABSTRACTFIBER REINFORCED POLYMER CONFINEDRC CIRCULAR COLUMNS SUBJECTED TOAXIAL LOAD AND BENDING MOMENTDoruk, KorayM.Sc., Department of Civil EngineeringSupervisor: Assoc. Prof. Dr. Barış BiniciJuly 2006, 79 pagesFiber reinforced polymers (FRPs) have gained increasing popularity inupgrades of reinforced structural elements due to high strength to weight ratio andease of application. In this study, the effectiveness of the carbon reinforcedpolymer wrapping (CFRP) on ductility and strength of circular reinforcedconcrete columns, made of low strength concrete, is presented. Four circularreinforced columns with similar dimensions, longitudinal and confining steelreinforcement were tested under combined axial load and bending moment. Threespecimens were strengthened with CFRP and the results were compared with thecontrol specimen. The main parameter of the experimental study was selected asthe level of eccentricity. First of all, the strain profiles of FRPs in thecircumferential direction were observed and the confining stress distributionswere examined. Then, an axial stress-strain model for FRP confined concrete witha transition from softening to hardening response for different confinement ratiosis proposed. The proposed model was verified by comparing the modelestimations with the test results obtained from this study and results reported byother researches. In addition, a parametric study was presented to obtain a simpleequation to estimate curvature ductility of FRP confined circular columns.
