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.

Defining initial geometric imperfections for the in-plane stability design of steel frames
The presence and form of initial geometric imperfections can significantly impact the structural response and the ultimate capacity of steel structures. Suitably chosen imperfections must be adopted during the design stage, particularly when utilising advanced analysis; applying inappropriate imperfections, either in terms of their shape or amplitude ...
