The Students themselves - Student Center Poříčí
Rypl Žabčíková, Ada ; Vrbka, Jan (referee) ; Makovský, Zdeněk (advisor)
Multifunctional corner house - Student`s center with residences, canteen and parking place underneath lying on the quai of the river Svratka, Brno, nearby 2 faculties, faculty of architecture and faculty of education. Main concept is "opening up". Opening up to the city and the river, however it means opening up between its inmates as well. Dynamic shape shows youth of the residents.

Stress, deformation and safety analysis of the tandem bicycle frame
Profota, Martin ; Dobeš, Martin (referee) ; Vrbka, Jan (advisor)
Purpose of this work was the evaluation safety and pliancy of the frame structure tandem bicycle using method of basic elasticity with the help of the deformation and stress analysis. After introduction material and geometry of the frame tandem bicycle introductory part is focused on theoretical basis of calculation like beam assumptions, definition the beam, limit states, Sentence of Castigliano and Saint Venant's Principle. Before commencement actual analytical solution the spatial task was transferred to plane task and used model was simplified. Calculation related to two load states differing by way of load of frame tandem bicycle. For each load modes comparison with numerical solution by FEM was enabled. Mathematical software like Mathcad 14 and Maple 13 were used to analytical calculation. Check was performed by numerical solution in program ANSYS Workbench 14.5.

Strength design of the press frame construction and the compliance calculation at the load position.
Dobeš, Martin ; Suchánek, Miroslav (referee) ; Vrbka, Jan (advisor)
The bachelor's thesis is intent on the calculation of a plane frame which is used for hydraulic press. The theoretical basis for the calculation is mentioned in the first part of this thesis. The calculation of a concrete exercise according to the task set in the bachelor's thesis is in the second part. As a frame model we used a plane frame with two crossbeams. The load on the plane frame is interpreted by solitary forces which work upon the crossbeams. The calculation uses the Castiglian's theorem to specify the unknown parameters from deformation conditions. The calculation considers flexion energy of tensity. In the next part of the calculation, we consider the energy of tensity caused by vertical and normal shear for comparison. Coordinates of the load position can be changed at will. The final results of the thesis are a concrete frame proposal and an examination of pliability of the frame. The calculation was carried out in MAPLE 11 software.

Residential Complex in Brno - Komín
Preininger, Petr ; Vrbka, Jan (referee) ; Makovský, Zdeněk (advisor)
The locality is one of the most desired in the city of Brno and its outskirts. My goal was to create an enclosed city block (a district in a district), where the neighbours know each other and therefore create a strong community. To ensure some degree of privacy I have divided the continuous longitudinal house block, which highlights the descend of the land, into separated groups of 3 to 6 terraced houses. To the groups I have then assigned shared gardens which together give impression of being one unit. The plot itself has the biggest value in todays state. The end of the village seamlessly turns into forrest which makes up for a barrier of some sort. The quality of the location lays in the contact with the forrest. That is the reason why I have decided to lower the building area under the visual horizon and keep the gardening colony, although on the roofs of the buildings.

LABORARTORY BRNO
Bártová, Markéta ; Vrbka, Jan (referee) ; Makovský, Zdeněk (advisor)
Gallery of modern art, architecture and design located on corner of Koliště and Milady Horákové streets. The building is divided into 3 functioning patrs, conected by gallery in the highest floor. The mass of gallery creates sheltered public space, follows the moovement of walkers and conects park Koliště nad street Kpt. Jaroše. Corner glass part belongs to the gallery and thanks to exhibits invites visiters already from afar. Tha space od gallery is free as possible for different kinds of exhibition. There are aula, cafe and salesroom part of the object too. There are 22+1 places for parking in the underground.

To Dvur Kralove by train - Transfer Terminal in Dvur Kralove nad Labem
Turčanová, Terézia ; Vrbka, Jan (referee) ; Ponešová, Barbora (advisor)
The task of this Bachelor thesis is to create an architectural and urban design of the transfer terminal in Dvur Kralove nad Labem. Therefore in my proposal, I design and integrate the transfer point into an existing built – up area, so it meets the demands of the 21st century passengers, encourages visitors to explore the city and meets daily needs and activities of the local community. Train and bus terminal together with various other services are combined under one roof to create a meeting place. The center of the area is an elevated glazed terminal hall that covers and connects various functions in the separate blocks within it. A distinctive unifying element of the entire terminal is the overlapping roof in the space around the hall and over platforms. The shape of pillars under the roof refers to the character of the industrial zone located nearby and the "lace-shaped" crossing of the ribs under the ceiling creates a specific atmosphere. The shelter over bus stops corresponds with the roof. Simultaneously it fills the interrupted street line on the Ulica 28. rijna street. The project of the area together with its surroundings also includes places for park greenery as well as for living that complement the missing public spaces in this part of town. The scale of objects is chosen with regard to the character of the site and its importance and location within the city, which has about 16 000 inhabitants.

Stress, deformation and safety analysis of the tandem trike frame
Tatalák, Adam ; Gayer, Tomáš (referee) ; Vrbka, Jan (advisor)
The bachelor’s thesis contains stress, deformation and safety analysis of the tandem trike frame of company AZUB. In the theoretical introduction is short introduction with alternative cycling. The beam assumptions are analysed and computational model of the frame is made. The entire calculation is focused on three typical load states – standstill (uniform rectilinear motion), deceleration and turn transit. The progress of inner stress resultants , tension and safety in critical point of construction are calculated. Deformation of the frame is solved for standstill, which is expressed by the shift center of gravity of the rider. For analytic calculation was used MATLAB software. Model of the trike is created in Autodesk Inventor.

Public facility centers in panel housing estates
Zvolská, Tereza ; Vrbka, Jan (referee) ; Mléčka, Jan (advisor)
Public facility centers were built at every housing estate as a background for a quality life, but they are not given much attention nowadays. At the same time, their central location, certain architectural qualities and load-bearing structure are good input attributes for the site's development. In my diploma thesis, I chose one such complex in Brno-Řečkovice to show on how to revitalize such objects. I make it a full-fledged part of the city district and at the same time a space that cerate its center.

Stress, deformation and strength analysis of the frontal recumbend axle
Valenda, Jakub ; Gayer, Tomáš (referee) ; Vrbka, Jan (advisor)
The bachelor’s thesis is focused on evaluation of tenseness and safety of a recumbert bike's front axle using method of basic elasticity. Calculation is limited to three options that differ in manner of frame's load. Used model of the axle is beam with two straight and one curved part. A bend and twist are considered as dominant stress. In conclusion there is for each load status evaluated the progress of tension on a beam's length, safety in critical point and deformation in point of power effect on axle. In my bachelor thesis there was used Matlab software for analytic calculation. Ancillary drawings were created in AutoCAD and Autodesk Inventor.
