diplomska naloga
Povzetek
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.

Design of observation tower in steel |
Sekundarni povzetek: |
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. |
