New trends in pavement maintenance
Březina, Ilja ; Stryk, Josef (referee) ; Hýzl, Petr (advisor)
The diploma thesis is dealing with the topic of new trends in asphalt road routine maintenance with a focus on new possibilities to repair damaged road surface, especially potholes and cracks. In the diploma thesis, a new advice which uses microwave heating in resurfacing asphalt roads was developed with the aim to observe its effectiveness and the optimal repair time. The obtained results were consulted with the producer of the equipment in order to utilize this new technology for repairing potholes and cracks on asphalt road surface in standard practice.

Studying the behavior of concrete at high temperatures
Tillová, Jana ; Herka, Petr (referee) ; Bodnárová, Lenka (advisor)
This master‘s thesis is focused on the study of the behavior of cement concrete at high temperatures with a focus on monitoring the impact of aggregate and cement type. This work describes the processes in aggregates and cement matrix at high temperatures. The theoretical part describes the selestion of a suitable aggregate and cement for the surroundings with potential exposure to high temperatures. In the experimental part is given design of composition of a concrete with two types of aggregates and four cements. It has been suggested 8 recipes. Changes were observed densities, compressive strength and tensile strength in bending, calculate the velocity of propagation of waves with ultrasonic pulsed method. Also evaluated the appearance of the surface samples after thermal load – cracks on the surface and measure the maximum crack width.

Static provision of baroque church
Kadlec, Jaroslav ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The master´s thesis solves a static provision of the Baroque church of Saint James in Městečko Trnávka. The church was built in 1752 in Baroque style on the place of the original Romanesque church. It is a single-nave building with dimensions of about 46 × 20 m. The nave is followed by a massive square tower with a height of about 34 m. The reason for the restoration of the church are cracks in the external masonry and arch due to small space stiffness. The building will be reinforced by horizontal and transverse prestressing. They are designed prestressing tendons, called monostrands, using method of alternative cable channels. It will help to avoid other derformations and it will increase a stiffness of the structure.

Evaluation of an inspection program and overhauls for ZLIN 26 aircraft
Jančář, Milan ; Finda, Jindřich (referee) ; Augustin, Petr (advisor)
This bachelor´s thesis deals with ZLIN Z 26 Series Aircraft maintenance and repairs procedures. Even the name shows, that this theme is very demanding and extensive. My interest was to explain some maintenance procedures of these aircraft and offer changes of it. In the beginning of this thesis we can briefly learn history of the ZLIN Aircraft and particular Z 226 Series models. There are mentioned difference maintenance procedures, applicable on the planes thru the service life time. Inspection and overhaul procedures are described in details and for better understanding were attached drawings or photos. Following chapter deals with evaluation existing inspections and overhauls - maintenance – procedures. Optimization of the maintenance is part of the chapter fourth, where is described possible innovation of the maintenance check list. In the last, fifth chapter, of this thesis are mentioned possibilities of the ZLIN Aircraft life time prolongation, which is actually discussed because of some aircraft of this type series reached basic life time limit, without any serious fatigue airframe damages appears.

Sewage pumping station
Čožík, Martin ; Perla, Jan (referee) ; Strnad, Jiří (advisor)
The subject of my bachelor’s thesis is static design of a sewage plant reservoir, dimensioning and examination of the construction part for Capacity Limit State and Applicability Limit State. Design documentation is included in the project. The aim of this thesis was to design the reservoir in such a way that there would be no cracks in the concrete. The calculations were carried out in accordance with Eurocode 2.

Sewage pumping station
Kustyánová, Orsolya ; Šulák, Pavel (referee) ; Strnad, Jiří (advisor)
This thesis deals with the design and assessment of all supporting parts of a reinforced concrete sewage pumping station in the village Vrbice u Velkých Pavlovic. The main parts of the thesis are the technical report, static analysis, drawing documentations and visualisations. Calculation of internal forces was performed by the software Scia Engineer and verified by manual calculation. The drawing documentation consists of shape and reinforcement drawings of supporting parts.

Space structure of industry building object
Pelikán, Adam ; Švaříčková,, Ivana (referee) ; Šimůnek, Petr (advisor)
The subject of this project is the structure of the storage hall which is made of reinforced concrete. It is designed as precast frame (span of 18m), founded on pocket footings. The roof deck (non-rigid) consists of ribbed slabs. The cladding is made of sandwich panels (reinforced concrete and isolation) layed on foundation beam. The design is focused on the single typical frame. Roof girder, column and pocket footing are designed. Designed life of the structure is 50 years.

Možnosti sušení dýh ve firmě DYAS.EU, a.s.
Foukal, Jakub
The bachelor thesis is focused on opportunities of passing the veneer through the dryer to limit the occurrence and size of cracks on the front ends of veneer sheets. In the first part there is a fundamental characteristic of layered solid materials. Other chapters deal with the production of plywood as such, production and worldwide trends. In the experimental part, there are ways of keeping veneer drying and processing quality veneers.
