Seismic behaviour of porous concrete buildings

U radu je opisano ispitivanje provedeno na potresnoj platformi dvaju troetažnih i jednog četveroetažnog modela zgrada izrađenih od porastoga beton. Zabilježeno je tipično ponašanje posmičnog zida s dijagonalnim pukotinama u smjeru uzbuđivanja i katnim mehanizmom ponašanja pri rušenju. Analizirani su odnosu između oštećenja, otpornosti i katnih pomaka za pojedina granična stanja, dana je ocjena za proračunske parametre, kao što su kapacitet pomaka i faktor ponašanja konstrukcije.The testing conducted on seismic platform to determine behaviour of porous concrete buildings, using two three-storey building models, and one four-storey building model, is described in the paper. Typical behaviour of shear wall with diagonal cracks in the direction of excitation, and with storey-based mechanism of behaviour during collapse, has been noted. Relationships between the damage, resistance and storey drift are analyzed for individual limit states, and an estimation of design parameters, such as the drift capacity and structural behaviour factor, is given
