<p>Savremene metode procene ponašanja konstrukcija u uslovima požarnih dejstava zasnivaju se na razvoju složenih numeričkih modela. U okviru disertacije, računski modeli razvijeni su korišćenjem komercijalnog programskog paketa ANSYS Workbench 16.0. Validacija i verifikacija modela sprovedeni su na osnovu rezultata eksperimentalnih i numeričkih istraživanja dostupnih u literaturi. Parametarskom analizom, utvrđen je uticaj požarnog scenarija, tipa agregata za spravljanje betonske mešavine, početnog nivoa opterećenja i prethodnog uticaja seizmičkog dejstva, na odgovor armiranobetonskih okvirnih konstrukcija u toku požara.</p> / <p>Contemporary methods for assessing the structural behavior under conditions of fire actions are based on the development of advanced numerical models. In the framework of dissertation, computational models are developed using commercial software package ANSYS Workbench 16.0. Validation and verification of the models are carried out based on the results of experimental and numerical research available in the literature. Parametric analysis is used to determine the influence of fire scenario, type of aggregate used for preparation of concrete mix, initial load level and the previous effect of seismic action, on the response of reinforced concrete frame structures during fire.</p>
