ABSTRACT / САЖЕТАК:

Procjena seizmičke otpornosti konstrukcija visokogradnje prema EC8 može se provesti ocjenom indeksa oštećenja. Primjena postupka pokazana je kroz studiju slučaja armiranobetonske skeletne zgrade spratnosti jedanaest spratova, izgrađene 1968. godine. Zgrada je bila izložena požaru 2014. godine. Za određivanje dinamičkih parametara  zgrade provedena je eksperimentalna i numerička analiza. Mjerenjem ambijentalnih vibracija i obradom u programu ARTEMIS definisane su realne vlastite vrijednosti analizirane konstrukcije. Numerička analiza je provedena na MKE modelu. U drugom koraku je provedena nelinearna dinamička analiza za 6 registrovanih akcelerograma potresa. Definisani su indeksi oštećenja i upoređivani za svaki registrovani potres. Prikazane su povezane vrijednosti indeksa oštećenja sa stepenima oštećenja definisanim prema EMS 98. Dati su određeni komentari i izvedeni zaključci.
