20.500.12556/DiRROS-22700 Projektiranje enoetažnih armiranobetonskih montažnih hal po novem Evrokodu 8 Povzetek projektiranja po metodi sil in njegova ocena z N2-metodo Design of single-story reinforced concrete precast buildings according to new Eurocode 8 Predstavljeni so značilni koraki in rezultati potresnega projektiranja širokega nabora enonadstropnih armiranobetonskih montažnih hal po metodi sil v skladu z drugo generacijo standarda Evrokod 8. Merodajen kriterij, ki je določal minimalne dimenzij stebrov, je bila omejitev njihovega maksimalnega pomika na največ 2% višine stebra. Pri projektiranju je bil v vseh primerih upoštevan faktor obnašanja q = 3 in reducirana efektivna upogibna togost, ki je znašala 50% teoretične togosti, ki ustreza bruto prečnemu prerezu. Potresni odziv tako projektiranih stavb je bil ocenjen z nelinearno potisno analizo (N2-metodo). Izkazalo se je, da je povprečni zasuk stebrov približno dvakrat večji od vrednosti, ki je bila upoštevana pri projektiranju. Tudi vplivi teorije drugega reda so bili, v splošnem, nepričakovano veliki, še zlasti v visokih stebrih, kjer so presegli dovoljene vrednosti. Glavni razlogi za velike razlike med elastično in nelinearno analizo sta bila poljubno izbrani faktor obnašanja q in poljubno reducirana efektivna togost konstrukcij, ki nista bila ustrezno korelirana. Efektivna togost v elastični analizi je bila približno dvakrat večja kot tista v nelinearni analizi. Podrobna analiza razlik med elastično in nelinearno analizo in postopek projektiranja, ki odpravi te razlike, sta prikazana v spremljajočem članku. The article provides an overview of the steps and outcomes of the force-based seismic design for a broad range of singlestory precast reinforced concrete buildings according to the second generation of Eurocode 8. The criterion defining the crosssectional dimensions of the columns was the 2% drift limitation. Buildings were designed considering a behaviour factor of q = 3 and an effective stiffness equal to 50% of the stiffness corresponding to the gross cross-section. The seismic response of the analysed buildings was evaluated using nonlinear pushover analysis (N2 method). It was found that the chord rotations of the columns were roughly double the value accounted for in the design. The second-order effects were also unexpectedly large, particularly in taller columns, where they exceeded permissible limits. The main causes for the substantial discrepancies between elastic and nonlinear analysis were an arbitrarily chosen behaviour factor q and an arbitrarily reduced effective stiffness, which were improperly aligned. The effective stiffness in the elastic analysis was nearly twice as high as observed in the nonlinear analysis. A comprehensive review of the differences between elastic and nonlinear analysis, along with a design method to address these gaps, is given in the accompanying article.
