Design of new konception of the structural design of the main wing hinges of the Z 242
Hála, Aleš ; Augustin, Petr (referee) ; Píštěk, Antonín (advisor)
This diploma thesis deals with modernization of the Z 242 L aircraft wing. The main emphasis is given to the connection of the wing and fuselage. The new concept of both main and rear wing spar is designed together with integral fuel tank. The strength of the structure is evaluated analytically and numerically by use of Finite element analysis. Wide range of milling operations is implemented into manufacturing process as well. This thesis shows how to innovate current aircraft with respect to feasibility of the design in case of future project realization.

Engineering design of conveyor
Chmelík, Jiří ; Čípek, Pavel (referee) ; Foltýnová, Dana (advisor)
The bachelor thesis deals with the design of a conveyor for transporting welded beams with variable dimensions. At the beginning of the work are listed some conveyors, which are commonly used in practice. Following analysis of available design solutions, design designs of equipment, their description and based on comparison was chosen the most suitable design solution. In the course of work is performed safety analysis of selected nodes. At the end of the work is evaluated the whole construction and elaborated the drawing documentation of the device. The proposed solution can also be used to transport parts of similar shapes.

Multi-storey building
Zaikin, Danil ; Bajer, Miroslav (referee) ; Bukovská, Pavla (advisor)
The subject of the thesis was the design of a multi-storey office building. In the transverse direction the building was designed as a three-tract 6.0 + 4.0 + 6.0 = 16 m. In the longitudinal direction 9x6.6 m = 59.4 m. The design was designed in several variants: articulated and frame in transverse directions. The joint variant was selected for detailed analysis.

Optimized design of reinforcement of concrete cross section
Hudyma, Nazar ; Laníková, Ivana (referee) ; Štěpánek, Petr (advisor)
The subject of this thesis is the optimization of design variables of reinforced concrete cross-section, especially its reinforcement. To solve this problem, it was first necessary to elaborate a search section that discusses various methods and approaches for solving the problem. The research part also includes processing and evaluation of tasks solved by other authors in available literature. For the optimization task, in the following parts both the general formulation and the detailed formulation of the partial parts of the concrete reinforcement structure optimization process are processed. As an example of optimization, a simple beam is chosen, which is subjected to bending moment and normal force one load case, where the example will be divided according to the formulation of both the function and the vector of unknown parameters (variables) defining the exact shape and properties of the reinforced concrete section. The examples will then be tested with regard to the speed of convergence and the degree of deviation between the best solutions found for each optimization algorithm used. At the end there will be a comparison and evaluation of the solution of the given task, as well as a summary of the whole bachelor thesis with reference to another possible direction in the optimization problems focused on reinforced concrete structures. In the appendices there will be a solution of selected examples.

Timber structure of a multipurpose garden house
Hoffmannová, Zdislava ; Barnat, Jan (referee) ; Šmak, Milan (advisor)
The subject of this bachelor’s thesis is a design of a timber structure of a multipurpose garden house. The ground floor of the house serves as a garage, the attic serves as a playroom for children. The building is located in Letohrad in Pardubice Region. Structural system is a timber framed structure which has been created as a spatial bar model in CADKON+ 2017 software. The internal forces have been calculated in SCIA Engineer 18.1 software using the linear static analysis. These forces have been used to design structural elements. Final results have been partially verified by hand calculations. Solid timber of C24 quality has been chosen as a proper material.

The Viewing Tower in Brdy
Kováčová, Kristýna ; Barnat, Jan (referee) ; Šmak, Milan (advisor)
The subjekt of this thesis is a design of a viewing tower located in the area of Brdy. The structure has been created as a 3D model, the internal forces have been calculated with the use o finite element method in a structural engineering software Scia Engineer 15.1. Based on the knowledge of theses forces the design of the structural systems has been done. The materials used on this construction are glued laminated timber and steel. The height of the tower is 25,725 m. The floor plan is a shape of a circle and fluctuating smaller with the gaining height. The main structural systém consists of 8 curved posts which are radiály situated on the circular floor plan. The tower has 3 observational platforms.

The multipurpose building in Pardubice
Tunková, Eliška ; Buchta, Stanislav (referee) ; Šmak, Milan (advisor)
The topic of my diploma thesis is a design of a construction of a multipurpose building. The floor plan is of irregular shape with a maximal span of 35 metres. There are two buildings in shape of a hexagon, to which another building in shape of a half of a hexagon is connected. Part of the building is designed as a two-storey building and all parts are different in height. The hight of the designed building in its highest point is 13,5 metres. The load-bearing structure consists of glued laminated wood elements and raised wood with steel elements used as fasteners. The construction is designed alternatively from wood and steel. The static solution was made using the RFEM software.

Okrajové úlohy pro rovnice 2. řádu se skákajícími nelinearitami
ZAHRADNÍKOVÁ, Michaela
The subject of this Thesis is to examine nontrivial solutions of boundary value problems for second order ODEs with unilateral jumping nonlinearities. Considered problems can be interpreted as models of a simple beam supported by three types of elastic obstacles. Couples of eigenvalues and eigenfunctions are found and discussed with respect to parameter which represents the strength of the obstacle.

The Forest Viewtower in Beskydy
Kamrádová, Michaela ; Straka,, Bohumil (referee) ; Šmak, Milan (advisor)
Topic of this Master's Thesis is a design and a statical evalution of a load bearing structure of an observation tower in Beskydy mountains. Ground plan of this structure is in a shape of a nonagon with a non-roofed interior space. Height of the observation tower is 38,5 m, the shape of a ground plan doesn't change with a radius of a circumscribed circle of 12 m. The structure is designed from glued laminated timber, solid wood and steel. Columns bear horizontal beams and their stiffness is ensured by horizontal and inclined reinforcing beams. Main load bearing columns, upper and lower beams are designed from glued laminated timber GL24h. Upper beams and beams of a gallery are designed from glued laminated timber GL36h. Horizontal stiffener is designed from solid wood C24. Central column, inclined beams, stairway, water slide cantilevers, rod and central rod are designed from steel of a strength class S235. Cantilever for gallery is designed from steel of a strength class S355. Connections are designed from steel elements. Statical evaluation, technical report and construction drawing are included
