Cable-supported bridge
Kovářová, Marika ; Bezručová, Kristína (referee) ; Nečas, Radim (advisor)
The theme of the thesis is to design a pedestrian bridge over a river. Out of two possible designs, the cable-stayed construction was chosen. The deck of the bridge is designed as a monolithic construction supported by cables from two inclined pylons. Two models were developed for the calculation of internal forces: a strut model for the longitudinal direction and a plate model for the perpendicular direction. These calculations were checked up by Finite Element Method (FEM) in SCIA Engineer 2017 software. Considerable part of the thesis was dedicated to the creation of so-called initial state. The design of the prestressing force and the evaluation of ultimate limit state and serviceability limit state was made in accordance with the codes currently in force. Small part of the theses is dedicated to the verification of the load bearing capacity of the pylon on the combination of normal force and bending moment with a subsequent verification in the software IDEA StatiCa9. The pedestrian bridge of 64,150 m length is considered as a perpendicular.

Complex design of the overhead line section of the transmission system
Reiskup, Filip ; Valiga, Matěj (referee) ; Ptáček, Michal (advisor)
The aim of thesis is a design of overhead lines of transmission system under specific weather conditions in given area. Furthermore, it gives a summary about the transmission and distribution systems and describes basics of overhead lines, used conductors and pylons in Czech Republic. It also presents the issue of climate conditions having a eminent influence on overhead lines. Moreover, theoretical part of thesis contains conductor mechanics and also mentions asymmetric state of overhead lines. Practical part deals with a design of specific part of overhead lines at voltage level of 400 kV and generally evaluates area where lines would be operated. In this area the new power energy source is hypothetically planned and therefore thesis analyzes possible variants of connection this source to transmission system. For one of these variants there are the calculations of two sections of the overhead lines under different weather conditions in more detail. The results bring longitudinal profile and assembling table for each section and they demonstrate the major impact of icing on the overhead lines.

Design of cable-stayed pedestrian bridge
Uher, Lukáš ; Kulhavý,, Tomáš (referee) ; Nečas, Radim (advisor)
This diploma thesis aims to design a structure of pedestrian bridge over the Svratka river. To make a preliminary study of possible bridging, three different outlines were drafted. The cable-stayed variant was selected for further analysis. Two towers, inclined in both their longitudinal and transverse direction, support a cast-in-place post-tensioned concrete deck through stay cables anchored in the tower and the deck. After determining the desired initial state, a finite element analysis was carried out using the Ansys software. The capacity of all main load-bearing elements was checked so it meets the ULS and SLS design criteria in accordance with EN 1992 codes.

Plan curved cable stayed pedestrian bridge
Müller, Radek ; Kaláb,, Pavel (referee) ; Koláček, Jan (advisor)
In my thesis, I created a study of plan curved cable stayed pedestrian bridge. As the main construction material is used prestressed concrete. Suspenders and railing are made from steel. The footbridge has a length of 130,00 meters and a width of 3,70 meters. The plan shape of the structure is composed of two oposite arches. Bridge deck is made of box girder. The bridge deck is single-side suspended on two concrete pylons with a height of 39,00 m. Pylons are supported by suspender.

Static analysis of cable
Pőthe, Péter ; Kytýr, Jiří (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis deals with the static analysis of suspension cables of the suspension footbridge. The processing was done as a manual calculation as using the program system RFEM for a static finite element method from company Dlubal. The task was to determine the geometric shape of cables and the real position of suspenders, which we get after the construction of the bridge. The results were then compared with each other.

Airport Terminal
Fojtík, Petr ; Barnat, Jan (referee) ; Pilgr, Milan (advisor)
My diploma thesis is focused on design and assessment of structural system of airport terminal. The design is processed in two options. Both of them has the same dimensions but structural system is changed. Floor plan is in the shape of part of annulus. Width of the hall is changing, in the middle of the hall is aproximatly 90 m. Length is 52,5 m, 10 m of this length is porch. Roof slope is 3° towards to the front of the hall.

Design of hydrogen pressure tank installation on the VUT 001 Marabu wing
Koštial, Rostislav ; Juračka, Jaroslav (referee) ; Píštěk, Antonín (advisor)
The content of this Master thesis to design installation of hydrogen pressure tanks for airplane VUT RAY 051. Survey was conducted of the available fuel cell on the market. Position of the tank was chosen over the wing using components for mounting a jet engine TJ100 M for aircraft VUT 001 MARABU. For fuel tanks were designed fairings. Further was calculated mass and centre of gravity analysis of aircraft, basic flight performance of aircraft and the drag variation in the location of the tanks above the wing. Further the strain and strength of hinges was calculated.

Steel structure of a military museum
Šašinka, Jakub ; Barnat, Jan (referee) ; Štrba, Michal (advisor)
The diploma thesis describes the design and assessment of steel structure of the roofing of the military museum in Králíky. The supporting structure of hall is 40.00 meters span. The total layout are 55.93 x 72.04 m, building height 11.43 m, 16.11 m pylon height. Main construction material is steel, grade S355, secondary constructions are made from steel grade S235, rods are made from steel grade S460. I did optimization of steel structure and chose the best option. For this option I made detailed structural analysis. It is prepared by static analysis of the main load-bearing parts of the structure, including joints and details. The supporting structure of hall consists in the transverse direction from the curved spatial lattice structure made of steel circular tubes which hang on rods on a sloped pylon. Part of the report is open-air roofing.

Suspension footbridge across the river
Chumová, Petra ; Bartoň, Jaroslav (referee) ; Nečas, Radim (advisor)
The subject of the thesis is to design a suspension footbridge over a river basin. Three different studies were created for the assigned problem. The suspension footbridge was chosen for the thorough elaboration. The most important part of the thesis is the static solution of the supporting structure. The structure model for calculation of impacts of selected strains including the impact of the footbridge construction was created in computational software Ansys. Assessment and dimensioning was carried out using manual calculation according the principles of limit states and applicable standards.

Footbridge across the expressway
Páleník, Petr ; Kocourek, Petr (referee) ; Nečas, Radim (advisor)
The aim of this master thesis is a design of the pedestrian bridge across the highway. The bridge is formed by a slab structure of 6 spans with lenghts from 9 to 51 m. The main spans are suspended on a V shape pylon. The deck of the span across the highway is assambled of precast segments and composite deck slab. The deck is in the lenghtways kept in the parabolic arch. The model of the construction is made in software ANSYS, the solution was done non-linear. The design and assessment are according to the europien standard.
