Cold-formed steel (CFS) members are susceptible to geometric imperfections due to the
high length-to-thickness ratio of the flat partitions, in other words, high slenderness …

The stiffness-tailoring capability of Variable Angle Tow (VAT) laminates gives enhanced
freedom to design thin-walled structures. One key advantage of tow steering is the ability to …

The optimal design of the postbuckling response of variable angle tow composite structures
is an important consideration for future lightweight, high-performing structures. Based on this …

The article examines a hot-rolled steel I-beam subjected to lateral-torsional buckling (LTB)
due to bending moment. The paper describes a non-linear finite element (FE) model and …

This paper is the second part in a two-part series that examines the role of geometric
imperfections in load–displacement response and collapse behavior of cold-formed steel …

Summary The Koiter‐Newton method had recently demonstrated a superior performance for
nonlinear analyses of structures, compared to traditional path‐following strategies. The …

The Koiter method recovers the equilibrium path of an elastic structure using a reduced
model, obtained by means of a quadratic asymptotic expansion of the finite element model …

A numerical stochastic strategy for optimising composite elastic shells undergoing buckling
is presented. Its scope is to search for the best stacking sequence that maximises the …

The design of lightweight structures is often driven by buckling phenomena. Increasing
demands for fuel-efficient aircraft structures makes post-buckled designs attractive from a …

The ultimate load-carrying capacity (LCC) of a steel structure is the theoretical maximum
load associated with the collapse of the structure. The high sensitivity of LCC to initial …
