Tensile behavior of high performance structural steel T-stub joints

Finite Element Analysis of Bolted T-Stubs Undergoing Large Displacement: A Preliminary Study

“…This is because the failure mechanism in these T-stubs is dominated by bolt fracture in tension before the flange undergoes large geometrical changes. By contrast, geometric configurations characterized by high m/db and thin flanges are strongly affected by geometric non-linearities, also reported by Zhao et al [7]. These large geometrical changes give rise to a deformation response which is characterized by the development of a second hardening branch in their corresponding F -Δ curve.…”

“…The critical displacement at which second order effects become dominant corresponds to the development of a new hardening branch in its global force -displacement (F -Δ) curve. Zhao et al [7] also highlighted the characteristic shape of the F -Δ curve for a Tstub as it undergoes large displacement -the second order effects arise from axial (membrane) deformation in the flange from its undeformed T-configuration. However, it is as yet unclear on how to quantify membrane effects in T-stubs.…”

Experimental behaviour of stainless steel bolted T-stub connections under monotonic loading

“…The structural behaviour of bolted T-stubs including the resistance, stiffness and deformation capacity, would be of great importance to design of bolted beam-to-column connections. A series of theoretical and experimental studies have been carried out to explore the inherent load-carrying mechanism and the prying effects, and corresponding design methods by considering the effect of the key parameters have been reported [5][6][7][8][9][10][11]. It was concluded that both the flexural strength of the flange and the tensile strength of the bolt contributed to the tension resistance and failure mechanism of the T-stub connections [12,13].…”

Experimental investigation and design of extruded aluminium alloy T-stubs connected by swage-locking pins

“…Owing to the nonlinearity, strain hardening behaviour and limited ductility of the material, the structural behaviour of aluminium alloy T-stubs may differ significantly from that of steel T-stubs, which have been widely studied [6][7][8][9][10][11]. De Matteis and his coworkers conducted 26 tests on welded aluminium alloy T-stub joints connected by bolts under both monotonic loading [12] and cyclic loading [13] and carried out corresponding numerical [14] and parametric analyses [15].…”
