Secondary title: Influence of masonry infill on seismic response of reinforced concrete frames
Secondary abstract: The graduation thesis deals with seismic analysis and design of fifteen storey reinforced concrete frame building for ductility class medium according to standard SIST EN 1998-1. The elastic analysis is performed with computer program SAP2000. Storey displacements and the influence of P-Δ are checked. The frame is designed according to capacity design rules for a peak ground acceleration equal to 0,25 g. The design process is presented in detail for selected beams and corresponding exterior and interior columns. Furthermore the same reinforced concrete frame with masonry infill is analised and designed. Masonry infill panels are modelled by means of diagonal struts. Similarly to the bare frame all the necessary verifications are made in order to design selected structural members. The design shear force of column is defined due to two most frequent failure mechanisms. The first one represents the shear strength of bed joints while the other corresponds to shear (diagonal) failure of masonry infill. Since infill is in contact with column, the design shear force is increased due to the effect of masonry infill. Based on the comparison of results for the bare frame and infilled frame it can be concluded that masonry infill has a significant influence on seismic response of reinforced concrete frames, since it reduces the storey drift demands and increases storey lateral force resistance.

Abstract (ePrints): V diplomski nalogi je predstavljena elastična analiza in projektiranje petnajstnadstopne okvirne konstrukcije srednje stopnje duktilnosti (DCM) v skladu s standardom SIST EN 1998-1. Elastična analiza je izvedena z računalniškim programom SAP2000. Opravljene so kontrole horizontalnih etažnih pomikov in vpliva teorije drugega reda. Okvir je dimenzioniran po metodi načrtovanja nosilnosti in sicer za območje, kjer refernečna vrednost projektnega pospeška znaša 0.25 g. Prikazano je dimenzioniranje grede ter robnega in notranjega stebra. Poleg čistega okvira je obravnavan tudi armiranobetnoski okvir s polnili. Ta so v modelu zajeta z nadomestno diagonalo. Tudi za okvir s polnili so opravljene vse potrebne kontrole ter dimenzioniranje izbranih nosilnih elementov. Pri dimenzioniranju stebrov je v tem primeru merodajna prečna sila določena glede na najpogostejša strižna porušna mehanizma. Prvi je prestrig polnila drugi pa strižna (diagonalna) porušitev. Upoštevano je povečanje prečne sile na steber zaradi vpliva polnil. Iz primerjave rezultatov potresnega odziva čistega okvira in okvira s polnili je razviden pomemben vpliv opečnih polnil na potresni odziv. Zmanjšajo se etažni pomiki ter poveča potresna odpornost konstrukcije.
