Abstract
Diplomsko nalogo smo razdelili na posamezne sklope. Najprej smo obdelali steklo in aluminij kot gradbeni material, saj je dobro razumevanje mehanskih lastnosti ter proizvodnih in obdelovalnih možnosti posameznih materialov pogoj za dobro razumevanje fasadnega sistema iz teh materialov. Ko smo osvojili ta znanja, smo lahko s pomočjo tehničnih rešitev izdelovalcev fasadnih sistemov razčlenili in obdelali aluminijaste fasade. Za dobro razumevanje samega sistema sem pridobil tudi vzorec stekleno-aluminijastega fasadnega segmenta. Področje potresno varnih stavb je – predvsem za Slovenijo, ki leži na potresno ogroženem območju – zelo pomemben del projektiranja, zato smo se odločili izvesti ciklične strižne preiskave, ki so nam približale obnašanje takšnega fasadnega segmenta pod vplivom horizontalne obtežbe v njegovi ravnini. Na osnovi eksperimentalno dobljenih rezultatov smo s parametrično analizo izdelali še numerični model enakih dimenzij kot je bil preizkušanec. Ta je služil za osnovo izdelave numeričnega modela večjih dimenzij, takšnih kot se pojavljajo v realnih fasadnih sistemih. Primerjali smo pomike, dobljene pri eksperimentalni in numerični analizi. Rezultat naših preiskav je odpor konstrukcije, ki jo nudi pri mejnem pomiku. Ugotovili smo, da je togost večje konstrukcije padla, saj smo obravnavali precej višji element; zato so manjši tudi zasuki in posledično notranje obremenitve ter poškodbe elementa.

Title:Experimental analysis of behaviour of glass-aluminium facade system segment exposed to in plane shear cyclic loading
Abstract:
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.

Keywords:glass, aluminium, aluminium facade, cyclic shear racking test
