Abstract
Ovaj rad opisuje analitički pristup proračunu spiralnih nosača. Nakon kraćeg uvoda u problem, prikazan je pregled i opis poznatijih metoda proračuna. Glavni izazov kod proračuna spiralnih nosača jest određivanje unutarnjih relacija u presjeku nosača. Svaka od metoda ima svoje prednosti i nedostatke, no ne daju sve metode jednako dobre rezultate. Dosadašnji pristupi uglavnom su razvijeni promatrajući betonska stubišta pa se u trećem poglavlju pokušalo pružiti poboljšanje proračuna kada su u pitanju čelični nosači te je prikazan prijedlog za daljnja istraživanja. Analiza spiralnih nosača nije jednostavna te kod njih dolazi do pojava koje još nisu istražene. U literaturi na hrvatskom jeziku za sada nema niti jedne literature koja detaljno opisuje spiralne nosače, bili oni betonski ili čelični. Cilj rada je, pored ostalog, provjeriti vjerodostojnost postojećih metoda pa je u nastavku rada proveden proračun na primjeru čeličnog stubišta s I-nosačem koristeći različite pristupe te su isti uspoređeni s rezultatima dobivenim metodom konačnih elemenata uporabom programskog paketa Ansys Workbench 17.0. U zaključku rada prikazan je osvrt na postojeće metode te je proširen prijedlog za daljnju analizu spiralnih nosača.
Abstract (english)
This final thesis describes analytical approach to computing helical girders. After introduction to the problem, common computation methods were reviewed. The main challenge to computing helical girders is determining internal reactions in any section of the girder. All of the methods described have their advantages and disadvantages, but not all of them provide as equally good results. Past approaches are mainly developed studying concrete staircases, thus the improvement to the computations were presented when it comes to steel girders in third chapter of this thesis. The analysis of such a problem is not simple, and there are phenomenons that haven't been investigated so far. So far in Republic of Croatia there hasn't been a single piece of literature that describes helical girders in detail, whether they're made of concrete or steel. The aim of this thesis is to, among other things, verify authenticity of existing methods so in the continuation of this thesis computations were performed on an example of steel staircase with I - cross section girder using different approaches and later compared with the results obtained by finite element method using the software Ansys Workbench 17.0. In the findings of the thesis, review was given on existing methods and proposal for further analysis of helical girders was expanded.
