Use of FRP Composites as Reinforcing Material for Concrete
Kratochvílová, Denisa ; Prokeš,, Jan (referee) ; Bodnárová, Lenka (advisor)
Because FRP composites have high fiber strength and good durability, they are increasingly used for repairs, modernisation and reconstruction of concrete structures. In practice, however there is a risk of premature separation of FRP reinforcement from concrete. This can be avoided by appropriate selecting the fibers and the matrix and the appropriate shape of the reinforcement. The actual materials and consistency of FRP reinforcement with concrete are also covered by this diploma thesis.

Technological stage of the gross superstructure of the apartment house in Prague - Dablice
Kucsera, Adam ; Kopecký, Lukáš (referee) ; Šlanhof, Jiří (advisor)
The work adresses the technological stage of the gross superstructure of the apartment house in Prague – Dablice. The house consist of reinforced concrete structure on the ground floor, three other floors in a brick form of pramic blocks Porotherm, ceilings above the second and third floor are composed of Spiroll prefabricated ceiling panel and roof structure is made up of gang nail trusses, thanks to this composition of house, it was necessary to address how to storage materials on the site, and also the arrival, departure and parking of vehicles. Technological regulativ is focused on concreting of the reinforced concrete monolithic framework.

Static solution of the ceiling structure of apartment building
Habanec, Kamil ; Nečas, Radim (referee) ; Zich, Miloš (advisor)
The Bachelor thesis deals with the static solution of the ceiling construction of an integrated apartment building. The aim is to design, or change the sizes of the projected structures in the submitted project, to ensure the interruption of thermal bridges and protection against foot noise. Subsequently, their static solution, dimensioning and assessment to marginal states. The elements intended for the solution are ceiling structures above the second upper floor, beams, a connecting staircase and a column. The calculation of internal forces was performed in the student version of SCIA Engineer 20.0 with a comparison of values on an independent simplified model. The work also includes drawing documentation for the aforementioned elements. The calculation was carried out according to the applicable standards and principles.

Sewage disposal plant
Doležal, Martin ; Kraut, Jan (referee) ; Šulák, Pavel (advisor)
This thesis deals with the design and static assessment of a concrete part of a sewage treatment plant. Specifically, the calculation and assessment of the base plate, external walls, internal walls and ceiling slabs, elaboration of shape and reinforcement drawings of selected structural element. The concrete part of the Sewage disposal plant is all below ground level. Static system and the calculation of internal forces was carried out in Scia Engineer 2011 - student version.

Reinforced concrete structure of a administrative building
Januš, Ondřej ; Švaříčková, Ivana (referee) ; Šulák, Pavel (advisor)
The main subject of this bachelor thesis is focused on the design of reinforced concrete locally supported slab of a multifunction building. Internal forces are calculated by a computer software SCIA Engineer and its resultes are compered with simplifield method. Another part includes the design of a reinforced concrete stairway and a column situated in the center of the disposition. The calculation method is based on ČSN EN 1992-1-1.

ASSESSMENT OF REINFORCED CONCRETE STRUCTURES EXPOSED TO ELEVATED TEMPERATURES
Rozsypalová, Iva ; Kolář,, Karel (referee) ; Vítek,, Jan (referee) ; Daněk, Petr (advisor)
Doctoral thesis is focused on the assessment of concrete structures after fire exposure and extends the knowledge in view of the main aims of the research defined in the objectives of his work. Thanks to the performed fire tests of full-scale concrete specimens, material characteristics corresponding to actual fire load have been assessed for different temperature levels. Resulting from presented research, main steps of assessment procedure have been recommended for both destructive and non-destructive tests of concrete after exposure to fire. Furthermore, behaviour of FRP reinforcement at elevated temperatures have been investigated. Aiming to determine the effects of fire exposure on reinforced concrete structures, experimental program have been defined and performed, including concrete beams reinforced with either steel, or composite reinforcement with glass or carbon fibres and subjected to experimentally simulated fire load. After cooling, bending test have been executed. Above mentioned experimental program was further complemented by extensive numerical analysis. Finally, presented work provides guidelines regarding further investigations required in this field of research.
