Sekundarni naslov: Analysis and design of flat slabs
Sekundarni povzetek: The thesis deals with the slabs on columns, which are in some cases also supported by beams. In the first part of the thesis the two mezzanine structures are modelled and analysed from the reference books of the program SAFE. For this purpose the computer program SAFE is used. We are trying to find out how to model eccentricity of the beams, that the structure as computer model gives results as similar to ones in the reference books. Slabs on columns and beams are in this purpose modelled with different linear and planar finite elements. It turns out, that it is difficult to make a recommendation how to model the slabs on columns and beams for numerical analyses by finite element method. Further on the thesis deals with the punching shear of slabs on columns. A comparison is made for three columns of fictitious mezzanine structure between the results calculated by the program SAFE and by the »hand« calculation according to the standard EN 1992-1-1. The reasons for differences are identified between the values of the results of programme SAFE and “hand” calculation. It turns out that ratios between the design shear force and the design punching shear resistance of slab given by the program SAFE are on the safe side. It also turns out that the necessary shear reinforcement for punching shear is not appropriately given by the program SAFE. Therefore this is properly determined by »hand« calculation. The last part of the thesis deals with the post-tensioned slabs.

Povzetek (ePrints): Diplomska naloga obravnava plošče na stebrih, ki so v nekaterih primerih podprte tudi z nosilci. V prvem delu naloge modeliramo in analiziramo medetažni konstrukciji iz priročnikov programa SAFE. V ta namen uporabimo računalniški program SAFE. Ugotoviti poskušamo, kako modelirati ekscentričnosti nosilcev, da se konstrukcija kot računski model najbolj približa rezultatom, ki jih podajata priročnika. Plošče na stebrih in nosilcih v ta namen modeliramo tudi z različnimi linijskimi in ploskovnimi končnimi elementi. Izkaže se, da je težko podati priporočilo, na kakšen način naj se modelirajo plošče na stebrih in nosilcih za numerično analizo po metodi končnih elementov. V nadaljevanju naloge je obravnavana problematika preboja pri ploščah na stebrih. Za tri stebre fiktivne medetažne konstrukcije je narejena primerjava rezultatov izračunanih s programom SAFE in »peš« računom po standardu EN 1992-1-1. Ugotovljeni so vzroki razlik med vrednostmi rezultatov programa SAFE in »peš« računa. Izkaže se, da so razmerja med projektno strižno silo in prebojno strižno odpornostjo plošče, ki jih poda SAFE, na varni strani. Izkaže se tudi, da program SAFE ne poda potrebne strižne armature na ustrezen način. Ta je ustrezno določena s »peš« računom. V zadnjem delu naloge obravnavamo prednapete plošče na stebrih.
