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.

Napjatostně deformační analýza rozhledny Hraniční vrch
Novák, Tomáš ; Skalka, Petr (referee) ; Fuis, Vladimír (advisor)
Bachelor thesis is focused on stress and deformation analysis of strut frame, which is based on lookout tower Hraniční vrch by the city Město Albrechtice. The main goal is to create simplified 3D model and his resulting analysis at various degree of static indeterminateness. The first part contains introduction to history of lookout tower, theoretical introduction to bar, strut frame and limit state, followed by calculation of three various static indeterminate level. In the last part is verification of analytic results by numeric method. Another goal is to create thesis, which will also give a guidence for future solver of more complex 3D strut frame.

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.

Deriving and Application of Analytical Design of Hammerspring in Firearms
Vobejda, Radek ; Polzer, Stanislav (referee) ; Slažanský, Martin (advisor)
The thesis deals with inference of analytic relations for calculation of pressure helical coil spring and considerates usage possibilities of simplified relations. In the thesis there is introduced analytic computation of slightly curvatured rod theory completed by finite element method calculations. The thesis describes two springs of firearm, which weren’t able to achieve required functionality. After this there was created a plan of concept particular spring on the base of derivated relations, which should be able to meet operative conditions.

Steel Beam Structure Optimization
Lamoš, Radek ; Eliáš, Jan (referee) ; Frantík, Petr (advisor)
The main subject of this work is to find ideal solution of the steel frame structure and offer the best solution to investors. The aim is to get know how steel structures works, write down internal forces when parametres are changing. Parameters can be profiles, loads or many others. The output should be perfectly optimized construction. The content combines theory of structural mechanics and designing steel structures. This project could be very useful in practice designing of steel frame structures with the possibility of expansion by other parameters.

Proposal of a program for solving of problems of simple tension/compression of bars and strut frames
Martínek, Tomáš ; Kubík, Petr (referee) ; Polzer, Stanislav (advisor)
The aim of this work is a program that will solve problems from the simple tension /compression bars and strut frames in the range of bachelor. The work consists of two programs developed in the Borland Delphi development environment. The programs allow the user to define a bar (strut frames) on the basis of the geometrical parameters and constraints, determine the rate of statical indetermination, make the necessary calculations and, if necessary, indicate the condition of deformation (a program for solving bars). The written part of the work serves as a manual.
