Numerical assessment of lateral distortional buckling in steel-concrete composite beams

Investigation of different infill wall effects on performance of steel frames with shear beam-column connections under progressive collapse

“…The simulation in the FE model used solid components ranging from 2 mm to 25 mm. Two-node linear 3D truss elements (T3D2) were used to generate the reinforcing bars (Rossi et al, 2020).…”

Resistant bending moment to lateral-torsional buckling of continuous steel and concrete composite beams with transverse stiffeners

“…These last two standards, however, deal with the phenomenon in a simpler way, based on the conventional theory of lateral-torsional buckling of steel profiles. Rossi et al [21] compared their numerical results with those of the four mentioned standards and highlighted that the Australian [17], [18] and American [19], [20] standards lead to more conservative results. According Rossi et al [21], the use of conventional theory of lateral-torsional with only the influence of the steel profile provides inaccurate results since the model is based on inappropriate hypotheses.…”

A procedure for calculating the resistant moment to LTB highlighted by Rossi et al [21] is proposed by Zhou and Yan [22], that doesn't need the initial determination of the elastic critical moment (Mcr).…”

A procedure for calculating the resistant moment to LTB highlighted by Rossi et al [21] is proposed by Zhou and Yan [22], that doesn't need the initial determination of the elastic critical moment (Mcr). This procedure provides good results, however, is valid only for composite beams subjected to uniform hogging moment.…”

Numerical assessment of effective width in steel-concrete composite box girder bridges

“…The steel-concrete composite structural elements are a solution that provides several advantages, such as the reduction of the element’s dimensions, the self-weight and the structural volume, the structural steel consumption, the foundation costs and also the improvement of dimensions accuracy. In recent years, several researchers have studied steel-concrete composite elements, defending their advantages and applications (Bezerra et al, 2018; Chen et al, 2019; Liu et al, 2017; Qiang et al, 2018; Rossi et al, 2020a; Rossi et al, 2020b; Xu et al, 2018; Zhou et al, 2018).…”
