Abstract

U ovom diplomskom radu obrađena je metoda postupnog guranja na postojećoj građevini izgrađenoj prije pojave današnjih propisa vezanih za potresnu gradnju. Statički sustav postojeće petero etažne građevine sastoji se od armiranobetonskog okvirnog sustava vitkih stupova i greda. Pomoću postojećih nacrta dobiven je solidan uvid u geometriju i raspored elemenata, a istražni radovi omogućili su informacije o čvrstoći ugrađenog betona, duktilnosti i rasporedu armature. Uzevši u obzir realno stanje konstrukcije proračunavati su bilinearni odnosno trilinearni dijagrami po normama HRN EN 1998-3 i ASCE/SEI 47-17. Prema dobivenim vrijednostima, u programskom paketu ETABS definirani su plastični zglobovi za sve stupove i grede statičkog sustava. Nakon toga, provedena je metoda postupnog guranja sa 10 različitih vrsta opterećenja radi dobivanja većeg broja mogućeg ponašanja konstrukcije. Dobiveni rezultati omogućili su uvid u raspored otkazivanja nosivih elemenata, do koje razine i za koju vrijednost maksimalnog ubrzanja tla.

Abstract (english)

In this study, the pushover method is applied on the existing building structure that was built without using the modern seismic design codes. The static system of the five-story building consisted of a reinforced concrete frame structure. With the help of the original design plans, a solid insight into the geometry and arrangement of the elements is obtained, and the researchwork provided information on the strength of the concrete, ductility, and reinforcement layout. Considering the real state of the structure, bilinear and trilinear diagrams are calculated according to the HRN EN 1998-3 and ASCE/SEI 47-17 standards. According to the obtained values, the software package ETABS defines plastic joints for all columns and beams of the static system. Moreover, the method of gradual pushing with 10 different types of loads is carried out to obtain a larger number of possible structural behaviors. The results provide an insight into the failure order of the load-bearing elements, the level and the value of the maximum soil acceleration.
