Welded I-section members are of common use in steel structures where they are employed
as columns and beams. Consequently, such members are subjected to compression force …

In this paper the Overall Imperfection Method, which is a well validated method for the
assessment of the global stability resistance of thin-walled steel structural members with any …

In this paper, a safety assessment of the General Method (GM) in Eurocode 1993–1-1: 2005
is carried out. The GM covers the stability verification of steel structures subjected to …

Single-layer reticulated shell is sensitive to imperfections. To clarify the effect of member
imperfection, nodal deviation and their couplings on load-carrying capacity of reticulated …

This article extends the innovative Overall Stability Design Method (OSDM) for steel portal
frames with double symmetric I and H cross‐sections. The OSDM utilizes linear buckling …

This paper presents a novel analytical expression to determine the elastic lateraltorsional
buckling resistance of I‐beams with corrugated web. The corrugated web beams have …

This paper discusses a combination of best practices and procedures from recent work in
Europe and the US, providing rational and economical calculations addressing the …

A new stability design method is proposed based on the results of the direct elastic linear
buckling analysis (ELBA). The method has a transparent and consistent mechanical …

Abstract The Overall Imperfection Method (OIM) is a more comprehensive version of the
Unique Global and Local Imperfection Method introduced for steel column design in EN …

The behaviour of steel structures is affected by two nonlinearities—the geometric and
material nonlinearity—and by the unavoidable presence of imperfections. To evaluate the …
