Analysis of lightweight aggregate concrete beams

U radu je prikazana mogućnost primjene lakoagregatnog betona u građenju armiranobetonskih elemenata naprezanih savijanjem. Obrazložena je opravdanost uporabe tog materijala za građenje niskih i visokih zgrada, mostova, industrijskih objekata te hidrotehničkih građevina, osobito u seizmičkim područjima. Postupci proračuna, dani za elemente naprezane savijanjem, od normalno teškog betona mogu se, uz manje izmjene, primjenjivati i za konstrukcije od lakog betona.The possibility of using the lightweight aggregate concrete for construction of reinforced-concrete elements subjected to bending stress is presented in the paper. The adequacy of this material for construction of low and high buildings, bridges, industrial facilities, and water engineering facilities, especially in earthquake-prone areas, is presented and substantiated. Computation procedures given for normal-weight concrete elements subjected to bending stress, can also be applied, with minor modifications, to lightweight concrete structures.
