Lateral torsional buckling of glass beams with continuous lateral support
Abstract There is a growing trend in steel glass facades to maximize the transparency of buildings with structural glass elements e.g. beams, columns, and stiffeners. A relatively new way is the use of glass beams in order to stiffen large glass curtain walls. Although the material glass is a material that is able to resist very high compression stresses, structural glass elements tend to fail because of instability due to their high slenderness. In the past years lateral torsional buckling of glass beams has been studied in many research works. The studies were limited to the fundamental situation of a simple beam without lateral restraint. However, in practice glass beams in glass curtain walls are fixed over the whole length to the front glazing panels by means of structural silicon joints or mechanical fixings. The load carrying behaviour of beams with lateral restraints is different compared to beams with a free lateral displacement. In this work, experimental and theoretical investigations on the lateral torsional buckling of monolithic and laminated glass beams with lateral restraint have been conducted. The objectives were to investigate the load carrying behaviour and to study possible design methods for stability-critical lateral supported glass beams. Finite element simulations were carried out and compared to experimental tests on real size glass beams made of monolithic and laminated glass. The design concept is based on well-known design concepts using buckling curves and non-dimensional slenderness factors.
