Abstract

Diplomska naloga obsega zasnovo in dimenzioniranje jeklenega razglednega stolpa, tloris katerega je enakostraničen trikotnik s stranico 7,7 m in višino 36,4 m. Osnovno konstrukcijo prestavljajo kotni profili. Stebri so spojeni iz dveh kotnikov, tako da je vmesni kot med profiloma 60 °, ki omogoča pritrjevanje diagonal in horizontal na steber. Horizontale so škatlastega profila, da so dovolj toge. Stopnišče poteka po obodu trikotnika, ki se na vrhu konča s razgledno ploščadjo, ki konzolno visi 1 m čez rob konstrukcije. Določila sem obtežbe na objekt. Veter, merodajna obtežba za dimenzioniranje, je določen po standardih SIST EN 1991-1-4 in SIST EN 1993-3-1:2007. Kritičen je izračun po zadnjem standardu. Določila sem notranje sile s pomočjo programa Scia Engineer in kotnike posebej preverila na uklon, saj ta program ne upošteva vseh dejavnikov za izračun uklona kotnikov . Zdimenzionirani so tipični spoji elementov, ki so večinoma členkasti in na koncu zbrani v detajlnih risbah.

Secondary title:	Design of observation tower in steel
Secondary abstract:	Graduation thesis design of steel observation tower, ground plan is equilateral triangle, which measures 7,7 m in length and 36,4m in height. The basic structure is made of elements with equilateral angle profiles. The columns are assembled of two profiles at an angle 60 ° that enables the connection between horizontal and diagonal on the column. The horizontal member is box profile which prevents large deflections. The staircase is extended in the rim of the triangle, which ends at the top with the observation platform 1 m over the structure. Wind had the biggest influence and is calculated according two standards SIST EN 1991-1-4 and SIST EN 1993-3-1:2007. The last one is relevant for the design. Internal forces are calculated by finite elements software Scia Engineer. The angle profiles are separately checked for buckling, because programe does not consider all parameters to properly calculate buckling. Typical connections are designed. They are mostly pinned. The detailed drawings are collected at the end.
