Abstract

Magistrsko delo prikazuje postopke in način projektiranja gladkih naknadno prednapetih armiranobetonskih plošč. Za postopke modeliranja, analize in dimenzioniranja smo uporabili sodobno programsko opremo za analizo konstrukcij z metodo končnih elementov. Predstavljeno je osnovno delovanje prednapetega betona, zgodovina njegovega razvoja in mehanske lastnosti vsakega od vgrajenih materialov. Podrobneje je razložena tehnologija naknadnega prednapenjanja armiranobetonskih plošč in vplivi prednapetih kablov na betonski element. Postopki projektiranja s pomočjo programske opreme so prikazani na reprezentativnem primeru naknadno prednapete plošče iz literature. Podrobneje so razloženi postopki modeliranja in analize prednapenjanja ter dimenzioniranja plošče. Izvedena je tudi primerjava med enako armiranobetonsko (AB) in gladko naknadno prednapeto (PT) ploščo na realnem primeru plošče hotela Atower. Namen primerjave je prikazati konstrukcijske in ekonomske prednosti PT plošč napram AB ploščam pri srednje velikih razponih.

Secondary title:	Design of post-tensioned concrete flat slabs
Secondary abstract:	The thesis describes the procedures and design methods of post-tensioned concrete flat slabs. For the purposes of modelling, analysis, and dimensioning, a contemporary software for analysis of structures by the finite element method was used. The basic functioning of prestressed concrete, the history of its development, and the mechanical properties of each incorporated material are presented. The technology of concrete slabs post-tensioning and the effects of prestressed tendons on concrete members are explained in detail. With the help of software, the design procedures are displayed based on a representative example of a post-tensioned flat slab from the literature. Modelling and analysis procedures of prestressing and slab dimensioning are thoroughly explained. A comparison between the same reinforced concrete (RC) and post-tensioned (PT) slab was carried out, based on a real example of the Atower hotel slab, the purpose of which was to show the structural and economic advantages of PT slabs over RC slabs in medium spans.
