Comparative analysis of post tensioned slabs with the span up to 15 m

Magistrsko delo obravnava dimenzioniranje gladke naknadno prednapete plošče po SIST EN 1992-1-1: 2005. V magistrskem delu je izvedena numerična analiza modelov T-prereza s programi Sofistik in Tower na primeru naknadno prednapete plošče z nizkimi in širokimi nosilci. Ugotovili smo, da je uporaba modela v programskem orodju Sofistik, kjer sta plošča in nosilec modelirana s končnimi elementi plošče in s skupno referenčno ravnino, primerna za analizo naknadno prednapete plošče z nizkimi in širokimi nosilci. Ugotovili smo tudi, da uporaba tega modela v programskem orodju Tower ni pravilna. Izvedena je tudi numerična analiza gladke naknadno prednapete plošče in naknadno prednapete plošče z nizkimi in širokimi nosilci. Analizo smo izvedli za več različnih razponov plošč, da bi ugotovili, kateri sistem naknadno prednapete plošče je najprimernejša rešitev glede na razpon. Ti razponi so bili 10,0 m, 12,5 m in 14,75 m. Primernost rešitev smo presojali glede na vidik najnižjih materialnih stroškov.The master \u27s thesis deals with the designing of a flat post tensioned slab according to SIST EN 1992-1-1: 2005. In the master\u27s thesis, a numerical analysis of T-section models is performed using software tools, Sofistik and Tower on the example of a post tensioned banded slabs with shallow beams. We have determined that in the Sofistik softweare tools the use of a model where the slab and the beam are modeled with plate finite elements with a common reference plane is suitable for the analysis of a post tensioned banded slabs with shallow beams. We also determined that using this model in the Tower software tool is incorrect. The analysis was performed for several different plate spans to determine which post tensioned slab is the most appropriate solution over the span. We determined which post tensioned slab system is the most suitable solution for the spans of 10,0 m, 12,5 m and 14,75 m from the point of view of the lowest material costs
