Steel members of double-symmetrical open
cross-sections are often used in engineering structures and
structures of buildings as columns and beams. Due to
connections of the members, transverse compression of the
cross-section webs can occur and is subject to structural
assessment. The resistance of the column web is influenced
by structural solution of the joint (welded, bolted, with end
plates) and possible interaction with axial force in the
column or shear. The paper focuses on numerical
investigation and quantification of the influence of axial
force in the column on behaviour and resistance of the
column web in transverse compression. The analysis was
performed using finite element method based computation
system and included both rolled and welded cross-sections
with various values of relative slenderness of the web. The
results were compared with results of transverse
compression resistance calculated using actual standard
for design of steel structures
