Buckling of viscoelastic laminated structural glass members: A novel practical approach using linear-elastic models

This study presents a methodology for estimating the critical buckling load of laminated glass plates, accounting for the time- and temperature-dependent behaviour of viscoelastic interlayers. The approach is based on a quasi-elastic approximation that allows the use of analytical expressions involv...

Sumario:This study presents a methodology for estimating the critical buckling load of laminated glass plates, accounting for the time- and temperature-dependent behaviour of viscoelastic interlayers. The approach is based on a quasi-elastic approximation that allows the use of analytical expressions involving an effective stiffness. The buckling parameters required in the expressions are obtained from simplified linear-elastic finite element models of the laminated structural glass. The methodology is general and can be applied to laminated glass members with any type of viscoelastic interlayer. This paper validates the proposed methodology through comparison with layered finite element models developed in ABAQUS, showing good agreement across different boundary conditions. The proposed method significantly reduces computational effort while maintaining sufficient accuracy for engineering applications.
