Abstract

Tema rada je usporedba utjecaja zahtjeva duktilnosti kod dimenzioniranja armiranobetonskih zidova jezgre visoke građevine. Izrađena su tri modela konstrukcije sa različitim visinama, dok je tlocrtni raspored zadržan konstantan. Nakon obrađenog teoretskog dijela opisa duktilnog ponašanja tokom potresa, provedena je analiza opterećenja, a zatim je dimenzioniranje provedeno prema DCM i DCH varijantama proračuna. Za sve modele su promatrani zidovi u prizemlju gdje će se javiti najveće rezne sile. Kompletan proračun je proveden u skladu sa HRN EN 1998-1-1 te je u konačnici napravljena usporedba rezultata. Kako je unaprijed bilo poznato da su uvjeti za dimenzioniranje prema DCH stroži nego za DCM, početne pretpostavke da će postojati razlika u zahtijevanoj armaturi, naročito onoj za posmik, pokazale su se točnima.

Abstract (english)

The subject of the thesis is a comparison of the influence of ductility requirements in the design of reinforced concrete core walls in high-rise buildings. Three building models with different heights were created, keeping the floor plan constant. After the theoretical part, in which the ductile behaviour during an earthquake was described, the load analysis was performed, followed by the dimensioning according to the DCM and DCH calculation variants. In all models, the walls on the first floor, where the highest moments and forces occur, were considered. The entire calculation was performed according to HRN EN 1998-1-1 and a comparison of the results was made. As was known in advance, the conditions for design according to DCH are stricter than those according to DCM, so the initial assumptions that there would be a difference in the reinforcement required, especially that for shear, proved to be correct.
