Abstract

Niz zastrašujućih potresa, koji su se dogodili 2020. godine u Hrvatskoj, osvijestio je potrebu za procjenom stanja i seizmički proračun postojećih konstrukcija jer većinu građevinskog fonda čine zidane konstrukcije kojima je istekao uporabni vijek trajanja. U ovom diplomskom radu provedena je detaljna procjena stanja i seizmički proračun postojeće konstrukcije u Zagrebu. Za samo razumijevanje potresnog djelovanja objašnjen je mehanizam nastanka potresa, bilježenje i lociranje potresa, razvoj potresnog inženjerstva u svijetu i u Hrvatskoj. Opisane su metode procjene stanja i metode seizmičkog proračuna. Za postojeću konstrukciju provedena je detaljna procjena stanja koja se sastoji od vizualnog i detaljnog pregleda. Provedeni su istražni radovi na postojećoj konstrukciju kako bi se odredile mehaničke karakteristike materijala. Postojeća konstrukcija modelirana je u programskom paketu 3Muri radi provedbe metode postupnog guranja. Provedena je pojednostavljena metoda proračuna otpornosti ziđa radi usporedbe rezultata. Osim procjene stanja i seizmičkog proračuna, dan je prijedlog za mjere sanacija postojeće konstrukcije.

Abstract (english)

A series of frightening earthquakes, which occurred in 2020 in Croatia, raised awareness of the need for assessment and seismic design of existing structures. Raising awareness is necessary because most of building stock consists of masonry structures that have an expired service life. In this master thesis, a complete assessment and seismic calculation of existing structure in Zagreb has been performed. For understanding of seismic action, the mechanism of earthquake occurrence, recording and locating earthquake, development of seismic engineering in the world and in Croatia are explained. Methods for assessment and methods for seismic design are described. For the existing structure, a detailed assessment has been performed. Detailed assessment for the existing structure consists of a visual and detailed inspection. In order to determine the mechanical characteristics of the material, on-site tests have been performed. The existing structure was modelled in the software 3Muri to perform a pushover analysis. To compare the results, a simplified method for calculating resistance of masonry walls was performed. In addition to the assessment and the seismic calculation, a proposal for measures to strengthen the existing structure are given.
