Laminated glass is widely used for facades in commercial and residential buildings. Special attention must be paid for such buildings when located on the earthquake prone areas. As glass is a brittle material and behaves elastically until failure, the designer must be focused on details and design of contacts between all the elements. Current design methods consider 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 box-type, composed of two timber frames in-filled with vertically load-bearing glass sheets and mutually connected with a solid laminated timber panel, which prevents out-of-plane deformation. Additional mass of 10t was applied on the top of the considered specimens which corresponds to a mass of three story above which is most likely to happen in a real building. Full dynamic testing of the model was conducted with the shaking table at the IZIIS laboratory in Skopje, Macedonia.
