Sažetak
Laminated glass with its physical and mechanical properties is widely used for façades in commercial and residential buildings. Special attention must be paid for such buildings when located on the earthquake prone areas. Glass as material is non-ductile and behaves elastically until failure, and for these reasons we must be focused on the details and design of contacts between all the elements of structural system. It is important to consider the dissipation of energy at the structural level and post fracture behaviour of the laminated glass itself. Current design according to Eurocode 8 considers the glass panels in glass facades as non-structural elements. This means that we have to neglect these elements when designing the building resistance for the lateral load imposed by earthquake. This paper shows the results obtained by seismic testing of timber-glass composite system. The model was composed of two identical innovative panels mutually connected with a solid timber panel which prevent out-of-plane deformations. Idea was to consider real 3-storey structure and in that respect additional mass was placed and connected rigidly to the wooden timber slab. The full dynamic testing of the model was conducted with the shaking table at the IZIIS laboratory in Skopje, Macedonia. Main purpose of the test was to develop a simple diaphragm configuration and to obtain the main characteristics under the effect of in-plane loads. Experimental results showed behaviour of the composite panels (and composite system) and the failure mechanism under strong earthquake load. Energy is dissipated through sliding of glass over timber frame and through activation of connectors in the corners of timber frame. Timber frame represents the protection of the glass panels and the connection between glass panels and main structures. The results will be used for development of a mathematical model appropriate for design of such structural elements.
