“…in greenhouses). Indeed, the performances of shear walls were extensively investigated in [17][18][19]. More recently, some researchers used glass panels to stiffen a steel framework [20] and as hybrid shear walls by the adhesive bonding [21] or friction connecting [22] of a glass pane to a wooden frame.…”

“…Therefore, the main structural elements of the TVT Pavilion are the transversal portal frames, the hybrid bracing system (walls and roof), and the front and back façades ( Figure 3). The TVT pavilion adopts the same principles of the TVTs, with advantages at the ULS and at the SLS confirmed by numerous experimental outcomes [18,19]. The installation sequence of the TVT Pavilion shall be conducted in accordance to the following steps ( Figure 4):…”

Abstract:In contemporary buildings, the architectural demand for a complete dematerialisation of load bearing structures can be satisfied only in limited cases with the exclusive structural use of glass. Otherwise, for challenging applications such as long spanned or high-rise structures, the use of hybrid glass-steel systems is mandatory. Glass, fragile but highly compressive resistant, is associated with steel, ductile and tensile resistant. The present research shows the feasibility study for a fully glazed pavilion made of six TVT (Travi Vitree Tensegrity) portal frames longitudinally braced by pre-stressed hybrid glass panels. The frames are about 20 m in span and 8 m in height. Appropriate multiscalar FEM numerical analyses, calibrated on the collapse tests performed on previous TVT large-scale prototypes, stated that the structural performance would be able to withstand heavy static and dynamic loads and stated the observance of the Fail-Safe Design principles.

“…In that study, careful consideration was paid for glass walls point supported to the substructure by means of bolted metal fasteners, as well as for glass panels linearly supported at the top and bottom edges only via partially rigid, flexible, linear adhesive joints. Wellershoff (2006) also accessed via experiments and FE simulations the buckling response of glass panels under in-plane shear and continuously, linearly supported along the four edges. Analytical and FE studies were proposed in (Bedon and Amadio, 2012) for the assessment of the buckling response and resistance of glass panels ideally simply supported along the four edges, under the action of in-plane shear loads.…”

Abstract:In this study, a unified design approach is assessed and proposed for the shear buckling verification of structural glass walls supported by non-ideal restraints. Based on the current trends of practice in buildings, the effect of (i) adhesive joints, (ii) metal frames with interposed adhesive joints or (iii) point mechanical connectors on the actual shear buckling behavior of the examined glass shear walls is properly investigated. The theoretical buckling resistance of the selected panels is first assessed by means of Finite-Element (FE) simulations, in the form of fundamental buckling shapes and Euler's critical loads. Analytical fitting curves of general applicability are proposed, so that the classical formulations derived from shear buckling theories could be used for a rational estimation of the Euler's critical loads, based on the restraints geometrical and mechanical features. As shown, the examined restraints have a fundamental role in the so predicted values and the assumption of ideal restraint configurations would unavoidably lead to unsafe, marked overestimations. Subsequently, the actual shear buckling resistance is also assessed, e.g., by taking into account the effects of possible initial geometrical imperfections, damage in glass or failure mechanisms in the restraints. Due to the implementation of accurate but computationally efficient FE models able to reproduce the desired mechanical effect of restraints, as well as any possible local damage in them, a rather close agreement is found with a standardized design buckling approach already in use for ideally simply supported glass shear walls only.
