Shape and Size of Initial Geometrical Imperfections of Structural Glass Members
Transactions of the VŠB – Technical University of Ostrava, Civil Engineering Series., 2017 Abstract In this paper measuring and determining of initial geometrical imperfections of set of glass members are presented. Measured specimens had the different dimensions and different composition – monolithic glass or laminated glass using different types of interlayer foils and glass panes.

Fourier representation of geometrical imperfection for probabilistic buckling analysis
Jurnal Ilmiah SINERGIThis research studies the first part of the failure of a compression member structure due to buckling. This unstable equilibrium collapse, exposes brittle failure which occurs suddenly and therefore should be avoided wherever possible.

Modelling Initial Geometric Imperfections of Steel Plane Frames Using Entropy and Eigenmodes
International Journal of Mechanics, 2023 The article introduces an innovative approach to modelling initial geometric imperfections in steel plane frames. Initial imperfections are introduced using the analysis of normalised deformations of elastic buckling modes. The scale of these modes is assessed by applying Shannon entropy and potential energy analysis.
