Abstract: Owing to possible saving in material weight, nonlinear and large deflection plate theory based on the von Karmen assumption has been commonly used in countries like France for economical design of thickness of aluminum and glass panels. With the trend of globalisation, it appears that Hong Kong engineers need to equip themselves on various new techniques for enhancing their competitiveness and non-linear analysis and design is considered to be one of these advanced techniques. Class panel is commonly used in curtain walls and glass structures. In this paper, the finite element program for large deflection analysis of plates and shells, NAF-SHELL, is employed to analyse the behaviour of thin glass plate by the van Karman assumption. The theory, practice and concept for non-linear analysis using a simple 8-bar truss model are addressed. From the conceptual 8-bar truss model, we can very easily visualise the region for tensile and compressive stresses and also the significance of large deflection in a glass panel.
