The graduation thesis is divided into the several parts. First a glass and aluminium were analysed as a construction materials. The detail investigation of mechanical properties, production and treatment possibilities of individual materials is a condition for good understanding of facade system, made from this materials. When we got the knowledge about the materials, we analysed and separated the aluminium facades with a help of tehnical system solutions, provided by facade system manufacturers. For a good understanding of system behaviour itself, we obtained the sample of glass-aluminium facade segment as well. Field of earthquake resistant building design is for us very important, because Slovenia is on the earthquake hazard area. We decided to do the cyclic shear racking tests, wich will better show the behaviour of facade system under the influence of in plane horizontal loading. On the base of experimental received results, we made a numerical model with the same dimensions, like the specimen. This was used as the basis for numerical modelling of the same system with bigger dimensions, the one that we can find out in real facade systems. We compared the shifts, which we got from experimental and numerical analysis. The results of our investigations is a resistance of structural element by the limited shift. We can conclude, that the rigidity of bigger structural element decreases, because of its enlarged height. The rotations are smaller and cosequently the internal loads and damages of element are smaller as well.
