Roof structure of construction for social purposes
Bašista, Ján ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The work treats the static recalculation of an existing roof structure of a construction for social purposes and proposes two variants of the design of a new roof structure. The construction has a rectangular ground plan of 30 m x 47 m and the roof structure is placed on the load bearing circumference concrete walls. Except for the load constituted by the function of the construction and by the climatic area, an extra load of 2 tons suspended at any place of the structure is considered because of the special requirement of working and technological equipment. The variant no. 1 is designed from the steel S355. The variant no. 2 is designed as a combination of the wood GL24h and the aluminium EN-AW 5083. Both of the variants have 11 transverse load bearing girders. The purlins are perpendicular to the girders and are placed on them. Stiffness is secured by roof stiffeners.

Concept of an In-line Spark-ignition Engine
Kočvara, Antonín ; Píštěk, Václav (referee) ; Drápal, Lubomír (advisor)
This thesis deals with comparison of straight four-cylinder petrol engine with a displacement of 1,5 litres and its three-cylinder alternative, which is based on a four-cylinder. The thesis starts with a research, where are examples of some currently manufactured engines. The research is followed by design of both engines, where the design of the crank mechanisms is made more in detail. After that, both crank mechanisms are subjected to dynamic analysis using FEM and MBS methods. The thesis ends with comparison of both engines in terms of crankshaft load, mass and dimensions.

Superstructure of the backpart of the family house
Jetmar, Ondřej ; Šulák,, Pavel (referee) ; Strnad, Jiří (advisor)
The thesis accommodates a design of a slab made out of reinforced concrete. On one side, the slab overhangs the load-bearing mansonry. The thesis comprises two solutions. In the first solution, the overhung part of the slab is not supported while in the second solution is this part locally supported by pillars. The thesis contains two variants of the slab design and also evaluation of the results.

Monolithic concrete building at sewerage plant
Klimeš, Petr ; Bažant, Zdeněk (referee) ; Strnad, Jiří (advisor)
Bachelor's thesis deals with design of monolithic concrete construction with a timber roof truss for a device of sewerage plant. This construction consists of these elements- strip foundation, walls with lintels, slab and timber trusses. This thesis contains static analysis of the component parts and their drawing documentation.

Design of outlet and intake objects of Nové Heřminovy dam
Neuvirt, Petr ; Švancara, Jiří (referee) ; Zachoval, Zbyněk (advisor)
In this thesis was presented Nové Heřminovy dam with basic parameters. Requirements on bottom outlets and intake objects are presented as well. Analysis of used valves on all dams in Czech Republic was done as an underlay for suggestions of bottom outlets in this thesis. The main task was to suggest three variations of bottom outlets. Differences are in number of outlets, dimensions, placing and valves. Then variation of intake objects. Each of variation was verbally described and filled with calculations.

Design of erosion control and flood protection measures in the plan of joint facilities in the cadastral area of Tučapy near Vyškov
Pavliš, Jaroslav ; Larišová, Lucie (referee) ; Dumbrovský, Miroslav (advisor)
The subject of this diploma thesis was to develop an analytical proposal for erosion control and flood protection measures in the plan of common facilities in the Tučapy district near Vyškov. Erosion protection was analyzed for EEA areas based on 4 variants including the current state without or with measures and climate change without or with measures. Agrotechnical and organizational measures, which includes contour cultivation with crop residues, or only crop residues, was considered as an soil erosion control application. The design and dimensions of stabilized paths of concentrated runoff also fell under the 4 variants of soil erosion protection measures. During the analysis, 4 critical profiles were identified, for which critical runoff were calculated for different Qn. This analysis of critical profiles also fell under the already mentioned 4 variants. This work was also supplemented by a direct design of flood protection with technical and organizational aspects, which were drainage ditches and strip crop rotation. The design of the jamming joints was based on 2 variants including the existing condition without conservation or with a coservation measures. The ArcGIS program was used to calculate erosion results and present analytical maps. The DesQ program was used to obtain the necessary volumes, flow rates and their graphs. Dimensioning of stabilized valleys and drainage basins was carried out using the Dimenzov program. The results of this work are intended to show the effectiveness and positive effects of anti-erosion and anti-flood measures.
