Abstract

Tema ovog rada je tipizacija aluminijskih montažnih hala s čeličnim umetkom s obzirom na različite zone djelovanja vjetra i snijega u Republici Hrvatskoj. Izrađena je dispozicija i proveden je proračun konstrukcije na mjerodavne zone opterećenja snijega i vjetra. Glavni nosivi sustav je dvozglobni okvir sa zategom. Analizirana je hala duljina 40 m, okvir raspona od 10, 12, 14, 16, 18 i 20 m i visine od 3,0, 4,5 i 6,0 m. Aluminijske prečke i stupovi su RHS profili 230x90x3 mm izrađeni iz legure AW 6005A , a na mjestima spojeva aluminijski profili su ojačani čeličnim RHS umetcima 180x80xt. Debljina stjenke čeličnog umetka varira od 3 do 6 mm uz klase čelika S235 ili S355. U analizi variraju i dužine čeličnih umetaka, u stupu od H/15 do H/5, a u prečki L/40 do L/10. Okvir je posebno provjeravan s profilima zatega RD 16 i CHS 101,6 x 4. Modeliranje i proračun okvira provedeno je u programu SCIA Engineer 19.1. Parametarske analize provedene su s obzirom na ujednačenost iskoristivosti mjerodavnih aluminijskih i čeličnih presjeka na temelju čega su dobivene optimalne duljine čeličnih umetaka za sve razmatrane geometrije okvira i zone djelovanja. Na temelju provedenih analiza predložena je preliminarna geometrija okvira i maksimalni razmaci između okvira koji mogu poslužiti za dosta precizno određivanje optimalne dispozicije aluminijskih hala u Republici Hrvatskoj.

Abstract (english)

The topic of this master thesis is standardization of aluminium prefabricated halls with steel insert considering different wind and snow loading zones in the Republic of Croatia. The disposition and design of the structure to the relevant snow and wind loading zones was performed. The main structural system is a double-hinged frame with a tie-element. Hall length of 40 m, frame spans of 10, 12, 14, 16, 18 and 20 m and heights of 3,0, 4,5 and 6,0 m were analysed. Aluminium beams and columns are RHS profiles 230x90x3 mm, with the joints reinforced with 180x80xt steel RHS inserts. The thickness of the steel insert varies from 3 to 6 mm and steel grade is S235 or S355. The lengths of the steel inserts also vary, from H/15 to H/5 in column, and L/40 to L/10 in the beam. The parametric analyses were performed regarding the uniform utilization of the relevant aluminium and steel sections, on the basis of which optimal lengths of steel inserts were obtained for all considered frame geometries and loading zones. Based on the performed analyses it is suggested that the preliminary geometry of the frames and the maximum distances between the frames can serve to precisely determine the optimal disposition of aluminium halls in the Republic of Croatia.
