Abstract

U radu se obrađuje primjena spregnutih konstrukcijskih elemenata u konstrukcijama višekatnih garaža. Budući da spregnuti konstrukcijski elementi ostvaraju veću otpornost i krutost pa samim time i veće raspone predstavljaju izvrsno rješenje za konstrukcije garaža. Rad se sastoji od teorijskog i praktičnog dijela. Prvi dio obrađuju vrste višekatnih garaža, osobitosti i položaj rampi te parkirnih mjesta, konstrukcijske elemente u višekatnim garažama te ekonomičnost konstrukcije. U drugom dijelu pojašnjavaju se osnovni kriteriji proračuna te provodi statički proračun na garaži koja se sastoji od 4 međuetaže oslonjene na čelične stupove. Proračun konstrukcije na krajnje granično stanje i granično stanje uporabivosti provodi se na numeričkom modelu garaže napravljenom u računalnom programu SCIA Engineer 21.1. Zatim su navedene vrste i karakteristike spregnutih stupova te objašnjen postupak njihovog proračuna. Kako bi se istražio utjecaj tipa stupa na konstrukciju garaže napravljena je usporedba različitih stupova. Korišteni su čelični HE 320 B stupovi, te spregnuti HE 320 B stupovi potpuno i djelomično ubetoniranih presjeka. Navedeni spregnuti stupovi dimenzionirani su na mjerodavnu kombinaciju iz statičke analize prema HRN EN 1994. Na posljetku, dimenzionirani su priključci, a priloženi su dispozicijsko rješenje, pregledni nacrti i nacrti detalja.

Abstract (english)

In this master thesis, the application of steel-concrete composite elements in multi-storey car parks is covered. Due to the higher resistance and stiffness, composite elements can reach larger spans and therefore are a great solution for mentioned structures. The thesis consists of two parts, theoretical and practical. In the first part different types of multi-story car parks are described as well as the characteristics and position of ramps and parking spaces, the types and construction methods of structural members and finally the cost-efficiency. In the second part, the basic design criteria are explained and the structural analysis is carried out for a multi-storey car park consisting of 4 floors supported by steel columns. The static analysis of the ultimate and serviceability limit states is applied to a numerical model made in SCIA Engineer 21.1. Furthermore, different types and characteristics of steel-concrete composite columns are specified and the analysis is described. To investigate the influence of column type to car park structure comparison between different types of columns is conducted. Steel columns with HE320B sections, concrete encased HE320B sections and partially encased HE320B sections were used. Columns with composite sections are analyzed according to HRN EN 1994. Thesis also includes connection design as well as disposition drawing, overview plans and detailing drawings.
