Reinforced concrete road bridge
Koumar, Jan ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The subject of this bachelor's thesis is the design of a reinforced concrete road bridge with one span over the river Oskava in the village Unicov. The bridge will convert road II/449 category S 7.5 / 50. Two shape variants of the cross-section were designed, from which a slab with a trapezoidal cross-section and a considered span of the bridge of 14.00 m was selected for the design and assessment of the load-bearing structure. The internal forces from the applied load were calculated on a slab model in SCIA Engineer 18.1 and compared with a manual calculation on a bar model using the method of resistive widths. The load-bearing structure is dimensioned for the ultimate limit state and the serviceability limit state.

Design of prestressed box gireder bridge
Hofírek, Radovan ; Jurík, Michal (referee) ; Zich, Miloš (advisor)
This thesis deals with bridging of a lowland valley and the creek Dolanský in the section Jánovce – Jablonov on the Slovak motorway D1. Four variants of the bridge have been developed. Subsequently prestressed single box gilder with large overhangs that are supported by precast struts was selected as the most suitable variant. The construction of the bridge will take place in a formwork suspended on overhead launching scaffolding. The static assessment according to the Europan standard has been drawn up for this variant. The load of the bridge is projected according to the ČSN EN 1991-2 - Traffic loads on bridges and the dimensoin of concrete structures according to the ČSN EN 1992-2 - Concrete bridges - Design and detailing rules. The calculation of load is done using computer software SCIA Engineer 10.1 and Midas Civil.

Wheel-mounted gantry crane
Hlobil, Jaroslav ; Kašpárek, Jaroslav (referee) ; Pokorný, Přemysl (advisor)
The aim of the present bachelor's thesis is a structural proposed design of a cantilevered frame, and also the structural proposed design of a wheel-mounted gantry crane, wheel-mounted gantry crane which is earmarked for a manipulation with containers on the containers' terminal surface. Additionally, the thesis deals with the proposed design of the prime load-bearing crane's components and with its strength analysis. Eventually, it also shows the mentioned proposed design with essential operational calculations, and the most important part devoted to the drawings' documentation.

Ultimita
Jindra, Daniel ; Kala, Jiří (referee) ; Hradil, Petr (advisor)
Structural beam and shell models were assembled in ANSYS program package. Design loads are defined according to Euro codes. Nonlinear analysis of structure has been established. Ultimate limit state of beams and cross sections were determined. Obtained results of ultimate limit state analysis were compared with Euro codes for design thin-walled steel structures.

Formula Frame Alternative Design According International Rules Requirements
Ondák, Lukáš ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
This master thesis describes design of frame construction of Formula Student car. The objective was to reduce weight and increase the torsional stiffness against to last version of the car. Next objective was to prove advantages of alternative frame. This had been achieved by gradual transformation of standard design of frame to alternative with the usage of FSAE alternative frame rules. The weight was reduced by 20% and torsional stiffness was increased by 34% thanks to FEM simulation and sophisticated changes of alternative frame design.

Static analysis and optimization of stress and deflection state of a lifting device
Okánik, Michal ; Vlk, Zbyněk (referee) ; Nevařil, Aleš (advisor)
The topic of this bachelor thesis is proposal and assessment of a lifting device according to current documentation and a new design of its construction and material solution. In the introductory chapter are described the features and requirements on a lifting device. In next chapter we deal with material solution of the problem. In the remaining parts of work, we focused on design of a beam model and detailed design of the plate joints using programs ANSYS and AUTOCAD, their subsequent calculation and assessment using the finite element method (FEM).

Frame of foundry trolley crane 330 t
Otevřel, Marek ; Kolář, Pavel (referee) ; Pokorný, Přemysl (advisor)
The topic of this diploma thesis is the frame of the foundry trolley crane 330/65/20t. The crane crab is used for handling with molten metal. The frame is analyzed by strength inspection and fatigue strength inspection. The process is according to ČSN EN 13001. The analyses are made by using finite element method on a beam and shell models. The diploma thesis was made in cooperation with the Královopolská a.s. company.
