چکیده
The test results on the performance of carbon fiber-reinforced polymer (CFRP)-confined reinforced concrete (RC) columns under axial compression load are presented in this study. Twelve slender CFRP-confined circular RC with a diameter 200 mm were divided into two groups. Six specimens different slenderness ratios 12, 20, 32, 40, 48, and 56 contained each group. experimental demonstrated circumferential CFRP wrap was effective enhancing ultimate compared unwrapped columns. investigation also showed that had important influences compressive behavior, bearing capacity decreased as ratio increased. In order to predict load-carrying capacities columns, formula proposed prediction agreed experiments. recommended be less than 26.5 practical engineering.

Theoretical model for slender FRP-confined circular RC columns
An important application of fiber-reinforced polymer (FRP) composites is to provide confinement to reinforced concrete (RC) columns to enhance their loadcarrying capacity. However, this application is generally restricted to short columns as existing design guidelines do not contain provisions for the design of FRP jackets for slender columns. This situation has been due to both the scarcity of...
متن کاملExperimental Study on Axial Compression Behavior of RC Columns Under Rapid Loadings
In this study, experimental study on six RC columns with different slenderness ratios under axial rapid loading was conducted to investigate the axial compression behaviour of RC columns considering the effect of strain rates. The failure pattern of the specimens and the relations of axial loading versus the axial deformation were described. From the test results, the specimens under static and...
متن کاملExperimental Study on Fibre-reinforced Cementitious Matrix Confined Concrete Columns under Axial Compression
Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix was developed, and experiments were conducted to establish its performance and analyse the mechanical properties under axial compression. The te...
