| Popis: | U radu je analizirano seizmičko ponašanje armiranobetonskih okvirnih konstrukcija različitih katnosti, projektiranih prema EC 8 i EC 2. Pri ovoj analizi primijenjen je probabilistički pristup gdje su u proračun uzete sve identificirane slučajnosti i neodređenosti. Ponašanje AB okvirnih konstrukcija prikazano je pomoću maksimalnog pomaka katova (engl. drift), dok je kao mjera intenziteta uzet spektralni odgovor ubrzanja. Rezultati provedenih analiza pokazali su da se seizmički odgovori uvećavaju za 31% do 54% ako se proračunom obuhvate slučajnosti i neodređenosti. The seismic performance of reinforced concrete frame structures of varying numbers of storeys, designed according to EC 8 and EC 2, is analyzed in the paper. The analysis is based on the probabilistic approach in which all identified incidental and indeterminate occurrences are taken into account. Performance of reinforced concrete frame structures is presented through maximum inter-storey drift values, while intensity is defined through spectral response of acceleration. The analysis results show that seismic response values increase by 31 to 54 percent if incidental and indeterminate occurrences are taken into account. |
