Abstract
This study presents experimental investigation of the structural behavior of reinforced concrete columns with hybrid cross-section (HSC and SFRC) and hybrid longitudinal reinforcement (steel and CFRP) bars. The experimental program included testing seventeen column specimens. One of column specimens was selected as a pilot column and sixteen columns were subdivided into 5 groups to study the effects of: type of concrete in the outer shell (HSC and SFRC), type of interface between core and shell (monolithic, surface intentionally roughened and surface intentionally roughened with shear connectors), type of main reinforcement and percentage of hybridization( ordinary steel and CFRP bars) and eccentricity to depth ratio (e/h) on the overal behavior, ultimate strength, deflection, cracking pattern, cracking load, modes of failure and ductility. All the column specimens have the same dimensions and tested under eccentric axial load only. The experimental work results showed that a significant improvement in the behavior and carrying capacity of the tested columns.
