Stress analysis of the only extant pier of the former Ivančice viaduct
Pelaj, Jakub ; Fuis, Vladimír (referee) ; Vaverka, Jiří (advisor)
The bachelor thesis focuses on the stress analysis of the original Ivančice viadukt pillar. The introductory part describes the theoretical basis necessary for the analysis. The second part deals with the history and assembly of the bridge. The third part dedicates to the creation of three-dimensional structure which serves as a basis for conducting the stress analysis. The following part provides a detailed expanation of the solution process and analytical calculations itself. In the conclusion, the obtained results are verified using numerical calculations a supplement with partial results concerning an additional type of load.

Model of the bridge for presentation of the member system
Chlup, Pavel ; Krejčí, Petr (referee) ; Appel, Martin (advisor)
In this bachelor thesis, the individual parts of the model bridge structure are explained with a brief commentary on their creation. Subsequently, the computational modelling of the problem using statics and its practical solution using strain gauges and MATLAB software is elaborated upon. The thesis is divided into a total of four chapters, where the first one is devoted to research on the application of statics and strain gauges. Subsequently, the function of each part of the fabricated model is formulated and a static model of the truss system which is equivalent to the fabricated model but is statically indeterminate without further considerations is presented. Then, the principle on which strain gauges are applied to solve the insolvability of the system is explained and as a result, the force action in the truss system as a function of the load is plotted using an application developed in MATLAB software. The result is a comparison of the measured and calculated values in the truss system.

Stress-deformation analysis of the indoor basketball construction
Kubíček, Daniel ; Kovář, Jaroslav (referee) ; Fuis, Vladimír (advisor)
The topic of this thesis is stress-strain analysis of a basketball structure in a gymnasium. This structure is divided into two parts. One part is modeled as a spatial bar system. The other part is modeled as a plane bar system. The first part of the paper deals with the research on the use of bar systems in sports. This is followed by the development of analytical computational models of the spatial and plane bar systems. These models are then used to calculate three different loading conditions. Subsequently, the models are developed for numerical solution. In the last part of this work, the analytical solution is verified by the numerical solution.

Creation of a program code for evaluation and display of inner resultants in beams
Kupka, Jiří ; Horníková, Jana (referee) ; Burša, Jiří (advisor)
The work is aimed at solution of problem with evaluating the values and courses of resulting inner effects. The goal is to algorithmize the calculation and its graphic interpretation. The main mphasis was on the correctness of numerical results and their correct depiction. Integral approach of olution and its logorithmization was chosen as suitable calculating model for given task. The algorithmus of the program itself was written in programming language C++. Thereinafter the basis of the sphere of tress and strain analysis in beams, the knowledge of which is neccessary for the given solution of the roblem or it is presumed.

Stress-strain analysis of a crane arm
Mora, Lukáš ; Halabuk, Dávid (referee) ; Fuis, Vladimír (advisor)
The content of this bachelor’s work is a summarization of types of tower cranes and subsequent stress-strain analysis of the crane arm of the crane type 150EC-B8 Litronic located on the Šumavská street in Brno. Analytical stress-strain analysis is calculated with equations of equilibrium using joint method in various types of loading of the construction with MAPLE software. Numerical calculation is executed on 3D model of the construction in software ANSYS. The aim of this bachelor work is the verification of the correctness and comparison results of analytic calculation with numeric calculation and evaluation of the results from a limit states and deformation standpoint.

Stress-strain analysis of Kozlov lookout tower
Winter, Josef ; Vaverka, Jiří (referee) ; Fuis, Vladimír (advisor)
Bachelor thesis is aimed at stress and deformation analysis of strut frame. The object of interest is lookout tower Kozlov close to the city of Česká Třebová in region of Ústí nad Orlicí in Pardubice Department. The main aim is to simplify 3D model of strut frame and its analysis. At the beginning I deal with history of lookout towers, theoretical introduction of bar, strut frames and limit states. Then follows modelling of 3D model with modified topology of bars and following calculation for different static loading and calculation for static determination. At the end numerical calculation was done to compare chosen model with analytic solution.

Finite element solution of axially loaded bars using linear element
Plucnar, Tomáš ; Návrat, Tomáš (referee) ; Vaverka, Jiří (advisor)
This bachelor thesis deals with the finite element method for axially loaded bars using linear basis functions. The theoretical part briefly describes the theory of axially loaded bars and states the individual steps that lead from the initial differential equation to a system of linear algebraic equations. A Weak formulation of the differential equation is used to derive the system. Using the theory described in the first part, an algorithm is created in Matlab, which is used to solve four problems. The results are then compared with the analytical solution and with the model in Ansys.
