Design of prefabricated aluminium structures

Dimenzioniranje aluminijastih konstrukcij, ki so izpostavljene zunanjim vplivom, je proces, pri katerem je potrebno upoštevati standarde, hkrati pa tudi pravila oblikovanja in dimenzioniranja konstrukcij. Podjetje Kreal, ki proizvaja osnovne elemente za sestavo takih konstrukcij, se s tem problemom srečuje vsakodnevno. V okviru magistrske naloge je bil za potrebe podjetja narejen preračun, s katerim so bili določeni zunanji vplivi s pomočjo standardov SIST EN-1991-1, ki vsebujejo napotke in pravila za določitev obtežb. Za lažjo in hitrejšo določitev obtežb je bil izdelan tudi uporabniški vmesnik za generiranje obtežb. Na podlagi obtežb pa je bila v programu Scia engineer narejena trdnostna analiza paviljona. Obstoječa konstrukcija je bila optimirana in dimenzionirana v skladu z zahtevami. V magistrskem delu se je mogoče srečati s preračuni na podlagi standardov, s trdnostnimi analizami po metodi MKE in z dimenzioniranjem konstrukcij iz aluminijevih zlitin. Uporabniški vmesnik in parametričen model konstrukcije pa omogočata hitro in enostavno določitev nosilnosti paviljona.Dimensioning of aluminium structures, which are exposed to outside influences is a process in which it is necessary to take account of standards, as well as rules of design and dimensioning of the structures. Kreal company, which produces the basic elements of the composition of such structures faces the problem every day. In the context of the master\u27s thesis the conversion was made for the needs of the company, which was to determine the external influences by means of SIST EN-1991-1, which provide advice and rules for determining loads. In order to facilitate and accelerate the determination of the loads the user interface for generating loads was made. On the basis of loads strength the analysis of the pavilion has been made in the Scia Engineer program. The existing structure has been optimized and dimensioned in accordance with the requirements. In this thesis it is possible to meet the calculations based on standards, with the strength analysis by FEM and the dimensioning of the aluminium alloy constructions. User interface and parametric model structure enable to quickly and easily determine the capacity of the pavilion
