A Model for Predicting Moment-Curvature Behavior of Self-Stressing Ssacfst Columns Under Low Cyclic Loading
Abstract:This paper reports the experimental investigation and theoretical model of self-stressing steel slag aggregate concrete-filled steel tubular (SSACFST) columns under low cyclic loading. Fourteen specimens including ten self-stressing SSACFST columns and four ordinary SSACFST columns (reference columns) are tested, and the effects of four experimental variables, such as axial compression ratio (n), diameter-thickness ratio (D/ts), shear-span ratio ( ), and expansion rate (Pct ) of steel slag aggregate concrete (… Show more
