Annotation: Šmykové namáhanie a pretlačenie bezprievlakových dosiek je intenzívne diskutovaná téma pri súčasnej tvorbe 2.generácie spoločných európskych noriem. Model podľa EN 1992-1-1 pre šmykové posúdenie bol pôvodne vytvorený a nakalibrovaný na základe výsledkov experimentov na vzorkách lokálne podopretých dosiek a následne extrapolovaný za účelom jeho použitia pri návrhu základových konštrukcií, resp. pre rohové oblasti stropných dosiek. Téma dizertačnej práce bude preto zameraná na aplikáciu nových modelov pre špecifické prípady šmykového namáhania ako: - pretlačenie dosky pri krajnom stĺpe, - zosilňovanie doskových konštrukcií na šmyk, - šmykové odolnosť dosiek namáhaných lokálnymi bremenami v blízkosti podpier, - pretlačenie dosiek vystužených nekovovou kompozitnou výstužou.
Annotation in English: Shear and punching of flat slabs is highly discussed topic in the current development of the 2nd generation of European standards. Currently used Eurocode 2 method for calculation of punching resistance of flat and foundation slabs and footings is based on the model which was published in Model Coode 1990. It is empirical model which was created and calibrated with the experiments mostly performed on slab specimens loaded under axis-symmetric conditions. The model was then extrapolated on the foundation structures and on the areas of flat slabs next to corner. New experiments out within last two decades have shown some imperfections of the model and necessity of its refinement. The topic of the dissertation thesis will focus on the application of new models for specific cases of shear such as: - punching of the flat slab to edge and corner columns, - shear strengthening of flat slab, - shear resistance of slab subjected to concentrated load, - punching of the flat slab with non-metallic composite reinforcements (FRP - fiber reinforced polymers).
