Seismic safety of prefabricated reinforced-concrete halls - analytical study

U članku se opisuje analitička studija potresnog rizika za armiranobetonske montažne hale. Uporabljen je histerezni model koji u obzir uzima smanjivanje nosivosti unutar pojedinoga ciklusa te pri ponovljenim ciklusima s jednakim pomacima. Model je uporabljen i za ocjenu rizika s analizom vjerojatnosti. Rezultati su omogućili kritičnu ocjenu odgovarajućih odredbi u normama Eurokod 8 iz 2004., posebno veličinu faktora ponašanja i time povezane veličine proračunskih sila potresa.The analytical study of prefabricated reinforced concrete halls is described in the paper. The use is made of hysteresis model which takes into account reduction in bearing capacity within a specific cycle and at repeated cycles with equal displacements. The model is also used in risk assessment with probability analysis. The results have enabled critical assessment of corresponding provisions contained in Eurocode 8, 2004, namely the performance factor and the related design earthquake force
