“…No soft layers were interposed at the glass‐to‐metal face. Later on, in ref., an extended FE investigation was carried out on double line friction‐grip connections, taking advantage of frictional tests presented in ref . Variations in stress distribution around holes, as well as expected failure pattern in glass plates was discussed via parametric FE studies, based on validation of reference FE models toward small‐scale experiments.…”

The consistent architectural transparency demand in buildings is highly promoting the structural use of glass, in combination or to replace loadbearing components made of traditional constructional materials. Despite its huge application in facades, roofs, envelopes, frame components, however, glass still represents a rather innovative and not well-known material, requiring specific design conceptsm and further extended studies, toward the fulfillme nt of safe design requirements. A key role in glass systems and assemblies involving multiple components is given to connections. Major issues in their design, consequently, arise from restraining single glazing elements, as well as from ensuring their mechanical interaction with other constructional systems, as a part of full 3D buildings, including several materials, and various loading/boundary conditions. In this paper, an overview of typical connection types in use for glass systems is presented, with special consideration for mechanical, adhesive, and laminated adhesive connections, giving evidence of their typical applications, evolution, current design issues. Existing research and major projects are also discussed, both at the material/component level as well as at the assembly level.

2 3Friction-grip bolted connections are theoretically well suited for the introduction of in-plane loads in glass structures because they distribute the load over a relatively large area and thus avoid critical stress concentrations. However, the performance of friction-grip connections for laminated glass may be jeopardised over time due to viscoelastic behaviour of the interlayers and gaskets used. More specifically, the latter may lead to preload losses in the connection. However, only a few technical papers have dealt with the use of friction-grip connections in laminated glass. Experimental tests were thus performed to study the time-dependent behaviour and the slip resistance of an existing connection. The latter consisted of a polyvinyl butyral laminated glass plate bolted to steel skew plates with preloaded bolts. Different materials (e.g. styrene butadiene rubber, nylon and polyoxymetheylene(-copolymer)) were investigated for the gasket, used to avoid direct contact between glass and steel. Specimens with and without a compression ring laminated between both glass panels were compared. The investigation very clearly demonstrated the importance of gasket design as well as the negative effect of interlayer creep on the performance of the investigated friction-grip connection.
