Abstract

U ovom diplomskom radu je provedena nelinearna analiza potresne otpornosti postojeće zgrade koja se nalazi u centru grada Zagreba koji je znatno oštećen prilikom potresa koji se dogodio 22.03.2020. U prvom dijelu rada opisana su karakteristična oštećenja tradicionalnih zidanih zgrada koja su uzrokovana potresom te raspoložive metode za proračun otpornosti konstrukcija na djelovanje potresa. U drugom dijelu rada temeljem numeričkog modela izrađenog u programskom paketu 3Muri v.14 provedena je analiza potresne otpornosti postojeće konstrukcije. U tu je svrhu korištena metoda postupnog guranja te je napravljena kontrola graničnog stanja znatnog oštećenja za povratni period potresnog djelovanja od 475 godina. Analizirani su relevantni rezultati numeričkih proračuna u svrhu identifikacije mehanizma oštećenja konstrukcije na temelju čega su dani prijedlozi za sanacije i ojačanja.

Abstract (english)

In this graduate thesis, a nonlinear analysis of the seismic resistance of an existing building in the city centre of Zagreb, which was significantly damaged during the earthquake of March 22, 2020, was performed. The first part of the thesis describes the typical damage to traditional masonry buildings caused by earthquakes, as well as available numerical methods for evaluating seismic performance. In the second part of the thesis, an analysis of existing building was performed using the 3Muri v.14 software package. The pushover method was applied and the significant damage limit state was analysed for a return period of 475 years. The relevant analysis results are presented and failure mechanisms identified. Based on the results, the recommendations were made for the rehabilitation and strengthening of the structure.
