| Popis: | Predmet ovog diplomskog rada je opis postupka proračuna zidane stambene zgrade te njezino modeliranje u programu 3Muri. Osnovne otpornosti koje je potrebno provjeriti pri proračunu zidane konstrukcije su: otpornost na vertikalna, horizontalna i bočna optećerenja te otpornost na vertikalno koncentrirano opterećenje. S obzirom na to da se područje Republike Hrvatske odlikuje izraženom potresnom aktivnošću, potrebno je odrediti i otpornost konstrukcije na potresna djelovanja. Prikazani postupak proračuna proveden je na jednostavnom primjeru višeetažne stambene zgrade s omeđenim ziđem, a zatim je ta ista konstrukcija modelirana u programu 3Muri. Ziđe je jedan od često primjenjivanih konstrukcijskih elemenata. Brojne zgrade novije gradnje su projektirane prema zahtjevima norme HRN EN 1996-1-1:2012 ali ipak, posebno na području Hrvatske, još uvijek postoji priličan broj starijih zgrada koje su izgrađene ne slijedeći nikakve norme. Pri proračunu takvih zgrada važnu ulogu pronalazi upravo program 3Muri koji nudi mogućnost modeliranja navedenih konstrukcija. 3Muri je program za proračun zidanih konstrukcija, ali i konstrukcija mješovitog sustava (ziđe-beton, ziđe-čelik) statičkim i nelinearnim statičkim proračunom postupnim guranjem. Spomenuti proračuni su provedeni za prethodno navedeni model konstrukcije s omeđenim ziđem, ali osim toga, napravljen je još jedan model u kojem je omeđeno ziđe zamijenjeno nearmiranim, te je na kraju rada proveden proračun i usporedba rezultata proračuna oba modela. The subject of this thesis is a description of the procedure for the design of a masonry builidng and its modelling in the 3Muri programme. The basic resistance to be checked in the analysis of masonry structure is: resistance to vertical, horizontal and lateral load, and resistance to vertically concentrated load. Since the territory of the Republic of Croatia is characterized by pronounced earthquake activity, it is also necessary to determine the resistance of the structure to seismic actions. The presented design procedure was conducted on a simple example of a multistorey residential confined masonry building. The same structure was then modelled in the 3Muri programme. Masonry is one of the most often used structural elements. Many buildings of newer construction are designed according to the requirements of Eurocode, but nevertheless, especially in the territory of Croatia, there is still a considerable number of older buildings built without following any standards. The 3Muri programme, which offers the possibility of modelling these structures, finds an important role in the design of such buildings. 3Muri is a program for the analysis of, not only, masonry structures, but also mixed system structures (masonry-concrete, masonry-steel) through static analysis (Eurocode 6) and pushover analysis (Eurocode 8). These analyses were made for the above-mentioned structural model with confined masonry, as well as for a similar model where confined masonry was replaced with unreinforced masonry. Finally, an analysis and comparison of the results of the analysis of both models were carried out. |
