Abstract

This paper presents the results of experimental studies on circular tubed steel-reinforced-concrete (TSRC) short columns subjected to axial and eccentric loading. A total of 12 columns with the key parameters of eccentricity ratio and diameter-to-thickness ratio of the steel tube were tested. The effect of shear studs on the co-work behavior of concrete and shaped steel was studied. The test results indicated that the shear studs affected little on the failure mode, bearing capacity and ductility of the eccentrically loaded circular TSRC short columns. Elastic-plastic analysis for the steel tube showed that the tubes at the compression side began to yield when the load approximately reached 90% of the peak load. Fiber-based numerical models for circular TSRC short columns were established and the results accorded well with the experimental results. Furthermore, the whole section plastic assumption in EC4 was adopted to determine the section capacity interaction diagram for circular TSRC columns.
