Design of a Steel Structural Building Using Double Split Tee Connections without Shear Tabs

Abstract

-Double split tee connection has various strength, stiffness, and energy dissipation capacity according to changes of thickness of T-stub flange and gauge distance, number, and diameter of high-strength bolt. If the double split tee connection is applied to a low-or medium-rise steel structure, a shear tab can't be applied for supporting shear force because of geometrical limitation. So it is required to propose details of improved double split tee connection to support shear force as well as flexural force. This research was performed to see if enough rotational stiffness is found when the double split tee connection without shear tab which was obtained through analytic and experimental researches by Yang et al. is applied to a low-or medium-rise steel structure. Also, it was seen if the low-or medium-rise steel structure having double split tee connection without shear tab has safe structural behavior, as well as material saving effect.
