Original Abstract
This paper deals with design procedure of structural glass beams subjected to lateral-torsional buckling. Because of slenderness of glass plates, it is necessary to the stability take into account. In detail, lateral-torsional buckling curves approach is described. Laminated safety glass members are used in structures in practise. Therefore effective bending stiffness, effective torsion stiffness and equivalent thickness of monolithic glass to be determined by sandwich theory. From parametric study, it is obvious that significant influence of critical lateral-torsional buckling moment (and hence bending moment capacity) has value of interlayer shear modulus. Polyvinyl butyral (PVB) foil is the most frequently used material for interlayer in laminated safety glass. Material properties of PVB depends on environment temperature and the load duration and it is not possible to simple determine of its. The results indicates that the critical lateraltorsional buckling moment of laminated glass beams (considering long load duration or high temperature) is four to five times lower than for equivalent monolithic glass beams.
