Abstract

U okviru ovog rada predstavlja se pojednostavljeni pristup procjene životnog ciklusa čelične višekatne konstrukcije sa različitim sustavima stabilizacije. Rad se sastoji od tri dijela. Prvi dio obrađuje teorijsku pozadinu životnog ciklusa građevine, gdje se tumače osnovni principi analize životnog ciklusa, razjašnjava pojam održivosti građevine i ističe važnost čelika za budućnost u pogledu održivosti. Pojašnjava se analiza životnog ciklusa s ekološkog, ekonomskog i socijalnog aspekta. Također se promatra zakonodavni okvir, projektantski pristup procjene održivosti te značaj modula D norme HRN EN 15804:2019 kojim se stavlja naglasak na recikliranje materijala nakon uporabe. Nadalje, u drugom dijelu rada se obrađuju temeljna načela i kriteriji po kojima se u nastavku provodi proračun. Provedena je globalna analiza konstrukcije i analiza opterećenja, nakon čega se vrši preliminarni odabir elemenata konstrukcije, a koji služi kao ulazni podatak pri izradi numeričkog modela. Zatim se provodi proračun konstrukcije na krajnje granično stanje i granično stanje uporabivosti, kao i proračun konstrukcije na djelovanje potresa. U radu je proveden proračun karakterističnih detalja. Posljednji dio ovog rada se odnosi na primjenu spomenute LCA analize. Prikazuje se usporedba dvije konstrukcije različitog materijala istih ulaznih parametara. Analiza životnog ciklusa posvećena je definiranju utjecaja konstrukcije na okoliš tijekom cijelog njenog životnog vijeka u cilju procjene održivosti.

Abstract (english)

This master thesis presents a simplified approach to the life cycle assessment of a multi-storey steel structure with different bracing systems. The thesis consists of three parts. The first part deals with the theoretical background of the building life cycle, where the basic principles of life cycle analysis are interpreted, the concept of building sustainability is clarified, and the importance of steel for the future in terms of sustainability is highlighted. The life cycle analysis from the ecological, economic and social aspects is explained. It also looks at the legislative framework, the sustainability assessment approach and the importance of module D from standard HRN EN 15804:2019, which emphasizes recycling materials after use. Furthermore, in the second part of the thesis, the fundamental principles and criteria are discussed, according to which the budget is implemented below. A global analysis of the structure and load analysis is carried out, after which a preliminary selection of structural elements is made, which serves as input data for the creation of a numerical model. Then, the design of the structure to the ultimate limit state and serviceability limit state, as well as the calculation of the structure to the effect of an earthquake, is carried out. In the paper, the calculation of characteristic details was carried out. The last part of this paper refers to the application of the mentioned LCA analysis. A comparison of two structures made of different materials with the same input parameters is shown. Life cycle analysis is dedicated to defining the impact of structure on the environment throughout its lifetime in order to assess sustainability.
