Design of Data Acquisition Equipment IMC Fastening System in the Car
Černý, Martin ; Jeník, Radomír (referee) ; Ramík, Pavel (advisor)
Devices for measuring the dynamic load and vibration of certain parts of the bodywork or parts of other parts of the vehicle are made using accelerometers and measuring instruments IMC. It must be simply installed into the interior of the vehicle so that it is not necessary to remove any parts of the interior and to avoid damage to all parts of the interior. The preparation must also withstand the considerable dynamic load generated by the harder operation tests.

Dynamic analysis of bridges structures
Prokš, Tomáš ; Salajka, Vlastislav (referee) ; Hradil, Petr (advisor)
The diploma thesis deals with dynamic analysis of cable-stayed steel pedestrian footbridge. The dynamic response of pedestrian-induced vibration was studied. The response of structure exeeded standard acceptance limit. Due to the effect of installed Tuned Mass Damper was studied. Motion equations of single and two degree of freedom model were solved in program MATLAB and the results were compared with numeric model in ANSYS.

Modeling of accidental torsion and its effect on spectral analysis
Šulerová, Zdeňka ; Nevařil,, Aleš (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis deals with the appraisal of concrete frame structures in seismic loadeffects. To calculate the simplified method will be used to support lateral forcesspecified in EN 1998-1:2004 - Design of structures for earthquake resistence. The calculation will be done by manual calculation and the calculation program RFEM. These alternative methods will be calculated loads and torques acting on the structure and subsequently compared. The main part of the bachelor's thesis is to evaluate the effects of the random distribution of mass,prescribed by the standard, and our chosen mass distribution, where we expect the maximum deformation.

Static and dynamic analysis of Prestressed bridge structure
Hokeš, Filip ; Nečas, Radim (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to perform static and dynamic analysis of prestressed concrete bridge structures in computational system ANSYS. For the analysis was chosen footbridge over the river Svratka in Brno. In relation to this topic are solved various types of modeling prestress at a finite element level. Before analyzing the footbridge is analyzed in detail the static system and the corresponding final geometry of the structure. Knowledge of the functioning of the static system is used to build the computational model of the structure, on which is subsequently performed static and dynamic analysis.

Brick Building Reconstruction
Kolářová, Jana ; Bažant,, Zdeněk (referee) ; Šulák, Pavel (advisor)
This bachelor’s thesis is focused on reconstruction of brick apartment houses in terms of static load capacity. The thesis summarizes the requirements and information to evaluate the current state of brick buildings, contains both theoretical and practical calculations to assess the load capacity of masonry elements, and suggests possible measures for structures in unsatisfactory conditions.

New Findings in Calculating of the Subgrade Response on High-Speed Lines to Train Passage
Petýrek, Michal ; Horníček, Leoš
The article presents the possibilities of approaches to the calculation of the subsoil response of a railway line to high-speed train running with a focus on Rayleigh waves. The article describes in more detail the approach to the calculation using the method of thin layers, which seems promising for the calculation of the response of the track with the construction of the track with transverse sleepers. The article is focused on this method with regard to the expected use of the track with sleepers on high-speed lines in the Czech Republic. Furthermore, the article mentions the implementation of nonlinear behaviour of soil under dynamic load during the passage of the train and the issue of calculating the subsoil of the line formed by multiple layers of soil with different parameters.
