چکیده
This study is dedicated to the development of a generalized confinement model applicable circular concrete columns confined by FRP full and partial arrangements. To simulate axial stress versus strain curve, new strength proposed addressing relation pressure during loading , whose calibration was based on an extensive set test results. By combining theoretical basis experimental observations, influence non-homogenous distribution transversal expansibility with full/partial compressive taken into account in establishment stiffness index. estimate ultimate condition fully/partially concrete, design framework also developed. It demonstrated that global stress–strain curves dilation responses simulated are good agreement those registered experimentally available literature, provides better predictions terms stress/strain than formulations standards.

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 کاملBehavior of FRP-Confined Concrete-Filled Steel Tube Columns
This paper presents the results of an experimental study into the behavior of concrete-filled steel tube columns confined by fiber-reinforced polymer (FRP). Eleven columns were tested to investigate the effects of the FRP layer number, the thickness of the steel tube and concrete strength on their load capacity and axial deformation capacity. The experimental results indicated that the FRP wrap...
متن کاملBehavior of FRP-Confined Reactive Powder Concrete Columns under Eccentric Loading
Fiber reinforced Polymers (FRP) have widely used for the purposes of enhances strength and ductility of concrete columns. Proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with FRP. In this paper, the influence of FRP thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...
