Abstract

U okviru diplomskog rada izrađen je projekt aluminijske kupole s promjerom baze od 18 metara i visinom od 9 metara. Kupola je smještena u Fužinama, a služi za meditaciju te je stoga natkrivena staklom. Rad sadrži dispozicijsko rješenje, te analizu i dimenzioniranje konstrukcijskih elemenata i priključaka prema HRN EN 1999-1-1. Uzimajući u obzir geografsku lokaciju i namjenu građevine, uz vlastitu težinu konstrukcije, uzeta je u obzir težina staklenog pokrova te djelovanja snijega, vjetra i potresa. Konstrukcijski elementi su izrađeni od aluminijske legure AW 6082 T6. Računalni program "SCIA Engineer 22.1" korišten je za trodimenzionalno modeliranje i analizu konstrukcije kupole. Kupola se sastoji se od 20 cijevnih rebara koji se protežu od temelja do tlačnog cijevnog prstena uz dodatak cijevnih dijagonala kako bi se osigurala potrebna otpornost i stabilnost konstrukcije. Provedena je nelinearna analiza konstrukcije, a konstrukcijski elementi su dimenzionirani na mjerodavnu kombinaciju opterećenja. Uz računalno dimenzioniranje prema Eurokodu 9 izvedeno je i ručno dimenzioniranje elemenata s najvećim iskoristivostima. Nadalje, provedeni su proračuni karakterističnih priključaka u vijčanoj i zavarenoj izvedbi pomoću specijaliziranog računalnog programa IDEA StatiCa. Ukupni utrošak aluminija iznosi 14 kg/m2 što čini ovu projektiranu kupolu pravom laganom i ekonomski isplativom konstrukcijom. Kombinacija aluminija i stakla daje 'prozračnu' konstrukciju koja svojim vizualnim identitetom uistinu odgovara ciljanoj namjeni građevine i predstavlja iskonski meditativni prostor koji se stopio s ljepotama Gorskog Kotara.

Abstract (english)

As part of the master's thesis, a project for an aluminium dome with a base diameter of 18 meters and a height of 9 meters was created. The dome is located in Fužine and is used for meditation purposes, which is why it is covered with glass. The work includes construction drawings as well as an analysis and design of the structural members and joints in accordance with HRN EN 1999-1-1. Taking into account the geographical location and purpose of the building, along with the weight of the structure itself, the weight of the glass cover, and the effects of snow, wind and earthquake were taken into account. The structural elements are made of AW 6082 T6 aluminium alloy. The computer software "SCIA Engineer 22.1" was used for the three-dimensional modelling and analysis of the dome structure. The dome consists of 20 tubular ribs extending from the foundation to the compression tube ring, as well as tubular diagonals to ensure the required resistance and stability of the structure. A non-linear analysis of the structure was carried out and the structural members were designed for the relevant load combinations. In addition to the computer-aided design according to Eurocode 9, a manual design of the members with the highest utilisation was also carried out. Furthermore, calculations of characteristic bolted and welded joints were carried out using a specialized computer software IDEA StatiCa. The total aluminium consumption is 14 kg/m2, which justifies calling the designed dome a truly light and economical structure. The combination of aluminium and glass creates an 'airy' structure whose visual identity truly corresponds to the purpose of the building and represents a meditative space that blends in with the beauty of Gorski Kotar.
