A bridge with one field over a watercourse
Pylypenko, Jevhenij ; Požár, Michal (referee) ; Strnad, Jiří (advisor)
The thesis focuses on the design of the superstructure of a new concrete bridge, which replaces an old substandard construction. The bridge should serve for passing roadway across the river Šlapanka, in village Mírovka, Kraj Vysočina. The static system of new construction is a one-span post-tensioned slab which is simple supported on edges. Span length of the superstructure is 17,5 meters. From three variants of concrete slab cross-section, a trapezoidal-shaped one was chosen. Concrete slab was assessed by the ultimate limit state and service limit state according to recent standards (Eurocode). The preliminary design of post-tension was processed according to standards (CSN).

Reinfoced concrete bridge over the Budišovka river
Sehnalová, Markéta ; Požár, Michal (referee) ; Koláček, Jan (advisor)
The aim of the bachelor thesis is the design of a single-span reinforced concrete slab bridge. Two variants of cross-section of the bridge were considered – rectangular and trapezoid. The rectangular one was chosen for further design. The wall-slab model was created using calculation software Scia Engineer 16.1. The structure is supported by pot bearings.

Pedestrian bridge over the Jihlava river in Třebíč
Vavřička, Lukáš ; Velešík, Marek (referee) ; Koláček, Jan (advisor)
The bachelor thesis deals with design of concrete pedestrian bridge over the Jihlava river. At the beginning two variants were created, one of which was future postprocessed. The cable-stayed construction, whose main support part is created by two pylons fixed to post-tensioned bridge deck, is pin-supported on abutment. Suspension of the deck is implemented by cables pin joined to the top of towers and sides of the deck. Material of the main concrete load-bearing structure is concrete C45/55. The steel elements of structure are made from steel S355, suspenders are designed with steel Macalloy 460. The structural assessment report was processed mostly by hand calculation with use of program MS Excel, for structural check of pylon use of program FIN EC beton was chosen. The load calculation was performed with program Scia Engineer. The drawing was created in AutoCAD software and the visualization in Lumion.

Study of new types of admixtures for waterproof concrete
Sikorová, Věra ; Másilko, Jiří (referee) ; Kalina, Lukáš (advisor)
This bachelor thesis is focused on the influence of crystallizing admixture for waterproof concrete. Reference concrete samples and modified concrete samples were prepared with different dosing of the crystallizing admixture, on which the standard test – the depth of penetration of water under pressure was carried out. The rheological properties of fresh concrete were verified by a slump test. The mechanical properties of the hardened concrete were examined by a compressive strength test. The mechanism of effect of the crystallizing admixture has been studied by scanning electron microscopy and X-ray diffraction analysis.
