Owing to its structural efficiency stiffened steel curved panels are increasingly used in
structural applications in civil, naval and offshore engineering. However, design provisions
to predict their strength are practically non-existent. Consequently, the aim of this paper is to
present a robust semi-analytical procedure for the prediction of the post-buckling behaviour
of unstiffened cylindrically curved steel panels under uniform uniaxial compression.
Nonlinear stability models based on large deflection theory incorporating initial …
