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).

Design of the RC slabs of the flat house
Reinoha, David ; Požár, Michal (referee) ; Klusáček, Ladislav (advisor)
The topic of the bachelor thesis is a new two-storey production building with an administrative part on the second floor and a production space on the ground floor The bachelor thesis deals with the static assessment of selected main bearing elements of the whole building in details for building permit. The main vertical supporting structure here is peripheral ceramic masonry, which is bounded by iron-concrete wreaths at the level of each of the two floors. The building is roofed with wooden nailed roof trusses placed on an in to wall-anchored wooden beam. The main supporting horizontal structure forming the ceiling between the first and second above-ground floors is made up of prefabricated Spiroll ceiling panels, which are placed on the stiffening wreath 1NP. The foundation structures are made of a monolithic concrete waist and consequently of a prefabricated lost formwork.

Reinforced concrete structures of a family house
Bátrlová, Petra ; Ducháč, Petr (referee) ; Požár, Michal (advisor)
This diploma thesis concerns with a design of structure of a family house, garage and supporting wall. Design of these structures was accomplished id software SCIA Engineer, which uses finite element method and was veryfied by manual calculation. Design was ma-de in accordance with applicable standarts. The results are drawings of reinforcement of family house.

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.

Concrete flat slab supported by columns
Turek, Jan ; Požár, Michal (referee) ; Perla, Jan (advisor)
This bachelor thesis deals with design of concrete flat slab of hospital building. The slab above the ground floor was designed. Internal forces were analysed with RFEM software based on finite entity method. Results were proved by the Direct Design Method and Equivalent Frame Method. The structural assessment was performed according to ultimate and serviceability limit states.

Strengthening of vaulted structures by prestressing
Požár, Michal ; Solař,, Jaroslav (referee) ; Drahorád,, Michal (referee) ; Klusáček, Ladislav (advisor)
The topic of this Ph.D. theis is repairing and strengthening of historical wagon vaults (barrel vaults, tunnel vaults) using post tensioning with tendons (monostrands) in longitudinal direction. The vaults should be without an edge, that´s mean the baroque vaults are well appropriate for this method. The pointed barrel vault should be problematic. The stabilization is for a wagon vault created by semicircle or segment part of a circle as well as an elliptic shape. The study has been made for vault with a width of 1 m and for the prestressing force has been used one tendon only. Of course, this method could be apply for normal constructions with a width of many meters. In this case, more tendons should be use with a suitable spacing. The goal of this work was to monitor an experiment model of an wagon vault and a real strengthened baroque vault of a church in Švábenice. During the monitor time, the static Analysis has been made. For these analysis appropriate finite elements in Ansys program has been use. The results of this work is to amplify the knowledge of the real behaviour of strengthened vaults, which could be use like instruction for the civil engineers. Further the public information guide to build an appropriate model of an Vault with an interaction with post-tensioning tendons.

Reinforced concrete structure of administrative building
Hejl, Zbyněk ; Požár, Michal (referee) ; Šulák, Pavel (advisor)
My bachelor thesis focuses on the design of selected parts of monolithic reinforced concrete structures of an administrative building. It is about a locally supported ceiling slab, an inner column and a staircase. Calculation of the internal forces was performed in the SCIA Engineer program and then verified by a hand method. The construction is assessed according to ČSN EN 1992 - 1 - 1.

Girder road bridge
Tang, Minh Phú ; Požár, Michal (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor thesis is to design a road bridge with a single span. The bridge carries a road of a class III., category S7,5, over the international roads E442. Three studies have been designed. Study C has been chosen for detailed elaboration. It is a monolithic double-girder post-prestressed construction. The calculation of load effects is performed in Scia Engineer 19.1. Only the effect of vertical load effects was considered, while the horizontal effects of the load were not taken into account.
