Preliminary Study on the Cyclic Response of Welded Joints with CHS Beams and Through-All Plates

Experimental and Finite Element Data of T-joints with Circular-Hollow-Section chord members

“…Consequently, examining joint hysteretic behaviour can be streamlined by concentrating on these critical components employing numerical modelling through appropriate multi-parameter mathematical expressions. In this framework, Sica et al [15] have focused attention on the cyclic behaviour of CHS to passing-through plate connections, which can be regarded as a standalone connection or a component of CHS to passing-through IPE beam-to-column joints [7] . Specifically, experimental tests and numerical simulations have been conducted on CHS to axially loaded passing-through plate connections under cyclic conditions.…”

“… The Finite Element (FE) analyses evaluated the force-displacement response of simulated T-joints, specifically focusing on assessing their initial stiffness, yield strength and damage. As highlighted in Sica et al [15] , these data were employed to formulate mathematical expressions for predicting the cyclic response of the analysed joint. The data discussed in [16] can be valuable for researchers and practitioners in the field of steel structures and beam-to-column joints, particularly for those focused on enhancing existing guidelines for predicting the flexural behaviour of connections involving tubular columns.…”

Cyclic behaviour of 3D cut welded connections with CHS columns and through I‐beams

“…Within this framework, this paper is focused on studying the cyclic behaviour exhibited by the analysed connection once all the nodal components have been characterised [10][11][12].…”

“…Instead, the components pct and pcc have been modelled employing the hysteretic model, whose parameters are assessed thanks to Eqs. (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). This numerical model has been validated against the 30 cyclic FE analyses on CHS to through-all double-tee beam connections presented in previous section.…”

“…through-all I-beam connections [8][9][10][11][12]. The first step of the investigation consisted in performing experimental tests and numerical simulations on beam-to-column subassemblies, which allowed proposing formulations to predict the flexural strength and initial stiffness of the analysed joint [8][9].…”
