This paper examines the overloading effect on the fatigue crack propagations monitored in a large-scale tubular X-joint specimen under two separate cyclic tests.The first cyclic test applies a constant-amplitude brace in-plane bending to the joint,with a single cycle of 150% overload before the crack depth reaches the mid-thickness of the chord.Uniaxial cyclic steel behavior and model for dissipative 2.2 Components of cyclic steel behavior 2.2.1 Cyclic hardening The cyclic steel behavior shows combined hardening,and the ultimate stress under cyclic hardening is significantly larger than the monotonic case (fu.cyc fu.mon).65-70% of the total cyclic hardening appears after the first cycle,additional 10-12% appears in the second cycle,andTohid Ghanbari-Ghazijahani - Google ScholarInfluence of a cutout on circular steel hollow sections under cyclic loading T Ghanbari Ghazijahani,H Jiao,D Holloway Journal of Constructional Steel Research 100,12-20 ,2014
