V diplomski nalogi je prikazan način projektiranja in dimenzioniranja gladkih armiranobetonskih plošč na stebrih. Diplomska naloga vključuje tudi preverjanje odpornosti plošče proti preboju. Poenostavljen postopek analize je izveden na podlagi analize z metodo nadomestnih okvirjev. Vsi statični izračuni so izdelani v programu za analizo konstrukcij SAP2000. V nalogi sta prikazana statična analiza štirih nadomestnih okvirjev, in sicer v vsaki smeri po dva nadomestna okvirja (en robni in en centralni okvir), ter dimenzioniranje dveh izbranih nosilnih elementov betonske konstrukcije. Gre za dve 30 cm debeli gladki armiranobetonski plošči, in sicer strešno in medetažno ploščo. Podprti sta z okroglimi armiranobetonskimi stebri, premera 50 cm. Na štirih mestih strešne in medetažne plošče je izvedeno preverjanje odpornosti plošče proti preboju (na mestu vogalnega stebra, dveh robnih stebrov in enega notranjega stebra). Dimenzioniranje stebrov in temeljev objekta ni predmet te diplomske naloge. Vsi izračuni so v skladu z veljavnimi Evrokod standardi in pripadajočimi nacionalnimi dodatki tem standardom. The graduation thesis presents the design and dimensioning of flat reinforced concrete slabs. It also includes a computational check of the punching shear resistance of the slab. A simplified procedure is carried out based on the equivalent frame analysis. All static calculations are carried out in SAP2000 software. The thesis presents the structural analysis of four equivalent frames, with two frames in each direction (one edge frame and one central frame), and the dimensioning of two chosen load-bearing elements of the concrete structure. The chosen load-bearing elements are two flat reinforced concrete slabs, more precisely a roof slab and a mezzanine slab, both 30 cm thick. These two elements are supported by round reinforced concrete columns, which measure 50 cm in diameter. The roof and mezzanine slabs are checked for punching shear at four points, more precisely at the corner column, two edge columns and one internal column. The dimensioning of the columns and the foundations of the building is not covered in this thesis. All calculations are in accordance with the relevant Eurocode standards and the corresponding national annexes to these standards. |
