Effects of Welding on the Tensile Performance of High Strength Steel T-stub Joints

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].…”

Analysis of Selected Properties of Welded Joints of the HSLA Steels

“…Taban, Kaluc, and Kocaeli [2] have considered application of the super-martensitic stainless steels (SMSS) as efficiently and effectively selected materials for fabrication of onshore and offshore pipelines. They also emphasized that fatigue loading behavior of welded structures, made of the super-martensitic stainless steels, has not been thoroughly investigated.Chen et al [3] presented an experimental studyof welding effects on tensile characteristics of the T-welds of the high-strength low-alloyed steel. Values of mechanical characteristics in the elastic zone, obtained experimentally, are higher than the related values calculated according to Eurocode 3 standard: steel constructions design [4], implying that the standard prescribes determination of the discussed weld characteristics of the HSLA steel in a conservative way.Zhang et al [5] presented experimental investigation of the welding influence on strength of the high performance steels and concluded that welding significantly softened the heat affected zone in the HSLA steel with insignificant effect on the normal strength.Durmusogly, Turker, and Tosun [6] were investigating gas metal welding (GMA) of the HY-80 steels with application of different welding parameters.…”

Investigation of the effects of bolt diameter and end-plate thickness on the capacity and failure modes of end-plated beam-to-column connections

“…It was reported that the difference between the experimental results and predicted value reached ratios of 1.73 and 3.0 for plastic and ultimate moment capacities, respectively. Apart from the studies of extended end-plated connections, the studies [20][21][22][23][24][25] conducted for T-stub joints revealed that the Eurocode also underestimates the resistance of T-stub joints.…”
