“…Besides using timber and load-bearing glass in hybrid structural systems, it is also possible to construct composite structural elements, where the two materials are bound together to form a common load-bearing mechanism as a single unit. One example of this idea is a recently developed concept, in which timber flanges are bonded to glass webs creating timber-glass composite (TGC) beams with improved load-bearing structural behaviour in intact state but also after initial glass failure (Kozłowski et al, 2014;Kozłowski et al, 2015;Dorn et al, 2014;Furtak and Rodacki, 2018). In general, the concept of TGC beam involves a transparent web made of glass (primarily annealed (AN) float glass) and timber flanges bonded together with an adhesive.…”

Glass structures have been increasingly utilised in modern construction for decades with load-bearing walls or facades as the most common elements. However, the use of glass beams has recently been given more attention but its application as load-bearing elements has been limited by the low tensile resistance, its brittle behaviour during failure and concerns of its performance in case of fire. Parts of these aspects can be covered by using Timber-Glass composites beams, with timber flanges and a glass web. Previous research and practical application show high potential for this type of composites in ambient temperatures but its performance in fire has not yet been assessed and thus not completely understood. This study describes what to our knowledge is the first full scale fire resistance tests of Timber-Glass composites beams. These tests results are also analysed using finite-element simulations in order to understand the mechanisms of failure during the tests. It was shown that adding a timber flange to a glass web can have severe complications for the fire resistance, however, there are many possible ways to circumvent these issues.

“…A composite beam consists of two or more structural elements which are permanently joined [ 10 ]. Timber can be combined with non-wood building materials, e.g., with steel [ 11 , 12 ], concrete [ 13 , 14 ], aluminium [ 15 , 16 ] or glass [ 17 , 18 ]. Furthermore, structural elements made of wood-based materials can also be combined with each other [ 19 ].…”

This paper presents an investigation of the load-slip behaviour of aluminium-timber composite connections. Toothed plates with bolts are often used for connecting timber structural members with steel structural members. In this paper, toothed plates (C2-50/M10G, C2-50/M12G or C11-50/M12) have been used as reinforcement in aluminium-timber screwed connections for the first time. The push-out test specimens consisted of laminated veneer lumber slabs, aluminium alloy beams, and hexagon head wood screws (10 mm × 80 mm and 12 mm × 80 mm). Of the specimens, 12 additionally had toothed plates as reinforcement, while 8 had no reinforcement. The load carrying-capacity, the mode of failure and the load-slip response of the strengthened and non-strengthened screwed connections were investigated. The use of toothed plate connectors was found to be effective in increasing the strength of aluminium-timber composite connections and ineffective in improving their stiffness. The examined stiffness and strength of the connections can be used in the design and numerical modelling of aluminium-timber composite beams with reinforced screwed connections.

“…Moreover, boundary conditions applied to the elastomeric layer, as well as the thickness of the layer, are of great importance. Moreover, to make analysis as simple as possible, polymeric adhesive layers can be combined in testing with materials of well-known and stable parameters, like aluminium [ 26 , 38 ] or glass [ 39 , 40 ]. Such composite structures can be easily tested, and parameters of elastomeric layers can be determined indirectly [ 41 ].…”

Experimental Study on the Effectiveness of Polyurethane Flexible Adhesive in Reduction of Structural Vibrations

The aim of the present study is to consider the idea of using polyurethane flexible adhesive in to reduce the vibrations in structures exposed to dynamic loads and evaluate their damping properties in relation to large deformations. Firstly, two aluminium cantilever beams, simulating structural elements (without and with polyurethane layer in the form of tape), were analysed, in order to check the damping of the unconstrained polymer layer. In the second stage of the study, a composite beam consisting of two aluminium flat beams bonded with polymer adhesive was considered, so as to check the damping of the constrained polymer layer. Dynamic parameters, such as modes of free vibrations, corresponding natural frequencies and damping ratios, were determined and compared. The third stage of the investigation was aimed at solving the problem of the additional mass of the applied polymer layer, which influences the frequencies and damping of the tested structure. A special separating procedure is proposed that makes it possible to calculate the corrected real values of the polymer layer’s damping. The results of the study clearly show that the response of the composite aluminium beam with and without polymer adhesive layer is mainly influenced by the layers’ thickness and the large strain deformation, in terms of its damping characteristics. The use of polymer adhesive layers in constrained and unconstrained conditions leads to a significant reduction in the vibrations of tested beams, while preserving their stiffness at nearly the same level. The applied analysis procedure made it possible for us to separate the damping properties of the analysed polymer layers and evaluate them independently with respect to the influence of integrated structural elements on damping.
