Analiza in dimenzioniranje etažne armiranobetonske plošče : diplomska naloga

Kališnik, Žiga (author), Brank, Boštjan (mentor)

V diplomski nalogi je predstavljena analiza in dimenzioniranje etažne armiranobetonske plošče. Določitev obremenitve plošče je narejena v skladu s standardoma SIST EN 1990 in SIST EN 1991-1-1, dimenzioniranje betonskega prereza pa po standardu SIST EN 1992-1-1, ki je namenjen dimenzioniranju betonskih konstrukcij. Analiza obravnavane plošče je izvedena z metodo končnih elementov v programu Safe. Opisan je postopek izrisa modela plošče za analizo v programu Safe. Glede obremenitve mejnega stanja nosilnosti je določena potrebna armatura plošče ter narejena kontrola strižne odpornosti betonskega prereza. Poleg tega so narejene kontrole za obremenitve mejnega stanja uporabnosti – omejitev pomikov in širine razpok plošče. Pri omejitvi pomikov sta upoštevana tudi vpliva lezenja in krčenja betona.

• Title: Analysis and design of reinforced concrete slab

Abstract

The graduation thesis examines the analysis and design of a reinforced concrete slab. Slab loads are based on guidelines from standards SIST EN 1990 and SIST EN 1991-1-1, and the design is made according to standard SIST EN 1992-1-1, which covers concrete structures' design. The slab is analysed with finite element method using Safe computer code. The process of modeling slab structure in Safe computer code is described. Based on loads from ultimate limit state reinforcement is calculated and shear resistence of concrete cross-section is checked. It is also proven that deflections and crack widths due to loads from service limit state are with maximum limit values. eflections are calculated with respect to concrete creep and shrinkage.
