Pedestrian bridge over the Dyje river in Břeclav
Tomášková, Eliška ; Kulhavý, Tomáš (referee) ; Koláček, Jan (advisor)
The subject of this master's thesis is the design and analysis of a concrete suspension footbridge, primarily focusing on the supporting structure. The strucutre was modeled in Midas Civil for longitudinal analysis, and additional model using SCIA Engineer was created to analyze the structure in a transverse direction. Assessment was done in line with valid standards.

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.

Cable-stayed bridge across the River Morava
Damek, Martin ; Páleník, Petr (referee) ; Nečas, Radim (advisor)
The subject of this master thesis is a design of a bridge for pedestrians and cyclists across the river Morava in Olomouc. Within the scope of thesis there are 3 studies of bridges. Cable-stayed bridge with prestressed spine beam was found appropriate and further calculations were assessed. Static calculations of prestressed spine deck and reinforced concrete pylon were made. Eigen frequencies and modes of construction were obtained. Internal forces were provided by SCIA Engineer with effect of non-linear parameters. Calculations were made according to valid standards and regulations.

Cable supported bridge
Kolář, David ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The topic of this bachelor thesis is design of a footbridge across a river. The final version, which has been chosen from three designs differentiating in their static behaviour of the structure, is a cable-stayed footbridge. The chosen option is designed as a parabolic monolithic prestressed deck suspended by cables anchored to two cone shaped pylons. The structure is situated perpendicularly to the riverbed and its total length is 57,465 m. Softwares, such as SCIA Egineer 20.0 and MS Excel, were used for the calculations of internal forces and modelling calculation models and its verification by hand. The design of the prestressing force, assessment of utility limit state and serviceability limit state were done by hand according to valid standards and regulations. Partially simplified bearing capacity assessment of the pylons was solved by IDEA StatiCa 9 software and some of the results were verified by hand as well. The thesis disregards stages of construction and prestress losses are estimated.

Static analysis of suspension bridge variants
Zavřelová, Michaela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor's thesis deals with the static analysis of individual models of suspension footbridges. A manual calculation of the cable was processed. The actual position of the cable was determined by calculation. The manual calculation was compared with the RFEM calculation program. Furthermore, the models were loaded with manually calculated loads. The bachelor's thesis deals with the influence of pylon deflection on the global deformations of cable and bridge deck during individual load cases and combinations. For one of the models, the optimization of construction was processed.

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.

Road bridge over the Kráľová waterworks
Pastucha, Marek ; Novák, Richard (referee) ; Nečas, Radim (advisor)
The subject of the thesis is the design of a road bridge over a river. A suspended bridge was chosen from three variants. The calculation of internal forces was done in the SCIA Engineer program and the assessment was done by manual calculation, in the MS Excel program and in the IDEA Statica program. The construction was assessed for the limit state of bearing capacity and usability. The calculation was made according to valid standards.standards.

Cable-supported pedestrian bridge
Knotek, Jan ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
The subject of this diploma thesis is design a cable-supported pedestrian bridge. Three different variants of the solution were created for the design. For detailed processing, variant no.2 was chosen - a suspended bridge with a pylon in the middle of the span. The main task is the static design of the supporting structure. The model for the lengthways is created in ANSYS. The SCIA engineer was used to solve crosswise. The assessment and dimensioning was done according to the limit state principles and valid standards.

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.

Bike bridge over the Nitra river
Teplanová, Alžbeta ; Páleník, Petr (referee) ; Koláček, Jan (advisor)
The subject of the diploma thesis is the design of variants of the construction of a footbridge for pedestrians and cyclists over the Nitra River. Two variants were created. After the comparison, a variant of the suspended footbridge was selected, which was modeled using the Midas Civil program and then statically assessed. The footbridge consists of a monolithic deck made of prestressed concrete. The pylons are located on one side of the bank
