Abstract

Steel columns composed of hollow structural section filled with concrete are one of the best solutions for providing the required strength and stiffness through the composite action of steel and concrete. The HSS column and steel beam connections proposed so far have included complex details and extensive welding in most cases, which complicates the construction of the connection and also its behavior. Hence, in this research, an attempt is made to avoid these complexities and to employ a connection with high efficiency and easier implementation by passing a continuous steel beam through tubular CFT columns. The influence of the steel tube diameter, the thickness of the steel tube, the thickness of the beam flange and web and also the amount of axial load applied to the column are investigated by numerical modeling using finite element method. The results of the pushover analysis show that the ratio between the bending moment capacity of the column and that of the beam (Mpc/Mpb) plays a significant role in the effect of the other studied parameters. In the range of Mpc / Mpb‌ < 0.6, variation of the the steel tube wall thickness directly influences the ultimate moment of the connection and its ductility. On the other hand, in the range of Mpc / Mpb > 0.6, the ultimate moment and ductility of the connection are directly linked to the thicknesses of the flange and web of the steel beam.
