This paper reports an investigation into the collapse behaviour of uni
formly compressed edge-stiffened thin-walled sections. The term 'edge
stiffener' refers to a stiffener in the form of a single or double rig
ht-angled lip formed at the free edge of the unstiffened element. The
primary function of the edge stiffener is to economically enhance the
local buckling of an open thin-walled section. An outline of a series
of tests on edge-stiffened thin-walled sections of various geometries
is given. Design procedures are proposed based on the modifications of
the draft Eurocode to predict the ultimate strength of such edge-stif
fened thin-walled sections. The empirical results obtained are then co
mpared with existing experimental results, and close agreement is foun
d. A further comparison with an independent source of experimental res
ults confirms the rationality of the approach.
