SHEAR BEHAVIOR OF STEEL TUBE CONFINED CONCRETE COLUMNS SUBJECTED TO COMPRESSIVE AND BENDING FORCES
This paper presents an experimental study on the shear behavior of steel tube confined concrete (STCC) stub columns subjected to compressive and bending forces. 26 specimens were tested to investigate the shear behavior. Parameters for the test were steel tube thickness, concrete cube strength, shear span ratio, axial compression stress-to-strength ratio and eccentricity. Their effects on the shear capacity of STCC columns were investigated. The failure mode, shear load-strain curve, shear load-midspan deflection curve and shear capacity of specimens subjected to different bending moment were obtained from the test. Based on the parametric study, a formula for calculating the shear capacity of STCC columns subjected to compressive and bending forces was derived. The comparison between calculated and experimental shear capacity values shows good agreement and the calculated results are at the safe side.
