Special Issue Information

Dear Colleagues,

Steel members have widespread applications in civil engineering structures, namely in bridges and buildings. The ongoing progress in computational tools and design codes, as well as aesthetic demands, is fostering the development of increasingly innovative and complex thin-walled steel load-carrying structural systems, which are generally highly susceptible to complex stability phenomena that need to be properly addressed during the design process.

This Special Issue aims to present recent high-quality original research concerning theoretical, numerical, experimental and design advances in the field of structural stability in civil engineering structures, including, but not limited to, the following:

  • Members (beams, columns, beam-columns) and structural systems;
  • Plates and shells;
  • Thin-walled members;
  • Advanced analysis methods;
  • Computational methods;
  • Carbon and stainless steel;
  • Static and seismic loading.

The absence of analytical expressions in current codes for evaluating the critical moment for lateral–torsional buckling of cold-formed beams with omega-shaped sections presents a fundamental challenge when assessing their resistance to global buckling. In response to this challenge, a comparative study was conducted to explore various approaches for calculating the critical moment. This involved both analytical and numerical analyses, using different methods available in codes and computational tools. The analytical analysis followed the Effective Width Method, employing the expression proposed in ENV 1993-1-1:1992, which is commonly used for evaluating the critical lateral–torsional moment of hot-rolled profiles. Numerical analyses were then performed using the ABAQUS v6.13, GBTUL v2.0, and CUFSM v5.05 software packages. The ABAQUS model, validated with results obtained from an experimental campaign, serves as the reference model. Upon assessing the bending moment resistances according to European, Brazilian, and American standards, consistency was found among these standards. However, it became evident that using the analytical expression proposed for hot-rolled profiles is inadequate for evaluating the critical lateral–torsional moment of CFS omega-shaped profiles. Conversely, the agreement between the ABAQUS, GBTUL, and CUFSM results suggests their utility as reliable tools for estimating the elastic critical lateral–torsional buckling moment. Full article
