Abstract

Povijesne jezgre raznih gradova Hrvatske karakterizira specifična blokovska gradnja zidanih građevina. Takvi su blokovi građeni u doba kada nisu postojali propisi za gradnju koja je uključivala u analize djelovanje potresa. Jedan od indikatora, uobičajen u suvremenoj gradnji, je da zgrade nisu odijeljene seizmičkim razdjelnicama, a međusobna heterogenost ima negativan utjecaj prilikom djelovanja potresnog opterećenja. Takav primjer nalazimo u centru Zagreba, posebno u Donjem gradu, gdje dodatno otežavajuću okolnost za bilo kakvu analizu stvara nedostatak dokumentacije (primjerice, nacrta) i podataka o održavanju i rekonstrukciji samih građevina. Međudjelovanje konstrukcija unutar bloka vrlo je kompleksno te trenutno nije dovoljno istraženo. U ovom je radu linearnom metodom primjenom spektra odziva provedena analiza ponašanja građevina na adresi Medulićeva 11 i 13 koje su dio Bloka 19. Napravljena je usporedba rezultata različitih inačica modela, a cilj rada je proučiti utjecaj okolnih građevina na promatranu. Za izradu numeričkih modela odabran je programski paket ETABS, Computers and Structures, Inc., temeljen na metodi konačnih elemenata. Zaključno, jedan od zadataka diplomskog rada je dati prijedlog ojačanja bloka bez zadiranja u izvornu nosivu konstrukciju pristupom s dvorišne strane.

Abstract (english)

Various cities in Croatia have historic cores characterized by masonry aggregate buildings. Such building blocks originated at a time when there were no regulations for designing a construction that included the effects of earthquakes. Furthermore, one of the indicators, common in modern construction, is that the buildings are not separated by seismic dividers and mutual heterogeneity has a negative impact when seismic loads are applied. Such examples can be found in the center of Zagreb, especially in the Lower Town, where the lack of documentation (for example, blueprints) and data on the maintenance and reconstruction of the buildings themselves impose additional problems for analysis. Altogether, the interaction of structures within the block is very complex and currently not adequately researched. In this work, an analysis of the structure behavior at Medulićeva 11 and 13, buildings part of so-called Block 19, was conducted by applying the linear method using a response spectrum. This thesis examined and compared model versions to analyze the influence of the surrounding buildings on the observed one. The software package ETABS, Computers, and Structures, Inc., based on the finite element method, was chosen for numerical model design. To conclude, one of the tasks of the thesis was to strengthen the block from the courtyard side, without encroaching on the original structure.
