ABSTRACT
The experimental and theoretical analysis of reinforced concrete masonry column subjected to eccentric loads was presented. Sixteen tests of reinforced concrete masonry columns had been performed. The effect of the slenderness ratio was the principal variable considered. The slenderness ratio varied from 6 to 18, while the steel reinforcement ratio and eccentricity remained constant. The mechanic properties and failure mode were studied in this paper. With the increase of slenderness ratio, the original tangent stiffness of the specimen gradually decreases, and the ultimate load-bearing capacity declines dramatically. Based on the experimental study and theoretical analysis, modification is proposed on the design equations of compressive capacity of reinforced masonry column in design codes, which can be provided as the design basis on reinforced concrete masonry column.
