Footbridge across the Labe
Krč, Rostislav ; Romportl, Tomáš (referee) ; Stráský, Jiří (advisor)
The thesis focuses on design of prestressed concrete footbridge which passes pedestrian and bicycle path over the Elbe river near city of Celakovice in the Czech Republic. Three different bridge options were analyzed and for further development a cable-stayed footbridge was chosen. Its bridge deck is formed of a box girder supported by cables in its vertical axis and all cable stays are anchored into two concrete A-shaped pylons. This structure was analyzed in SCIA Engineer and assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Both the global structural behavior and the local structural integrity of box cross-section were assessed as well as construction stages and cross-sections of pylons and cable stays. Assessments were performed in IDEA StatiCa combined with hand calculations. Eventually a dynamic response of structure was analyzed. Natural modes and frequencies were found and forced oscillation response was evaluated. The thesis includes technical drawings, construction process and visualization.

Multi-span bridge structure
Necid, Miloš ; Brtáň, Stanislav (referee) ; Koláček, Jan (advisor)
I deal with the road bridge near Velké Meziříčí in the thesis. The highway bridge overcomes valley 360 m long and 36 m high. For each course there is a separate super-structure. Each of the support structures converts three stripes of road transport. I do calculation of internal forces both manually and in Scia Engineer. In the thesis is drawings, showing the gradual construction, diagram of prestressing and reinforcement.

Container gantry crane
Švub, Pavel ; Malášek, Jiří (referee) ; Pokorný, Přemysl (advisor)
This bachelor's thesis deals with the design of the supporting structure and crane travel of a rail mounted gantry crane for handling containers at container depot. The work includes the calculation of the load acting on the crane, the design and stress analysis of individual parts of the supporting frame and the design of the crane travel, including its drive. One of the outputs of this work is the attached drawing documentation.

Design of doublebeam of bridge crane 50 tonne
Matěja, Josef ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
The Bachelor’s thesis deals with the design of two-girder crane bridge for the lifting capacity 50 tons. The process is split in eight parts. The first one contains a preliminary scheme of the whole design and proposal of main parameters. The second part contains calculation of preloading of the girder, specification of its main dimensions and calculation of maximum bending moment. The other parts include calculations and designing of individual main parts and accessories such as crane girder, cross girder, wheels, rails, gear and brake. The bachelor’s thesis has been elaborated using the relevant technical literature and standards that contain procedures and recommendations for calculation and designing of bridge cranes.

Continuous concrete bridge structure
Zemánek, Tomáš ; Lerch, David (referee) ; Koláček, Jan (advisor)
The diploma thesis is focused on solving road bridge situated between Roudno and Razová village over the water basin Slezská Harta. Before the design itself 3 studies were created and compared together. The selected variant is a continuous box girder with inclined walls, post-tensioned by bonded cables. The girder of a total lenght 148,0 m and width 13,6 m is divided into three spans. Height of the girder is 3,3 m. A detailed structural design, including construction limit state assessment, prestress design and time dependent analysis verification is processed. The design and the assessments of temporary and permanent situations are made according to valid standarts and regulations. Drawings and vizualizations are parts of the diploma thesis.

Plan curved pedestrian bridge
Lachová, Alžběta ; Jurík,, Michal (referee) ; Koláček, Jan (advisor)
The subject of this master thesis is the elaboration of a study of a curved footbridge leading over the Svratka River. Two variants were created, from which a suspended structure was selected for subsequent modelling and assessment. The footbridge consists of a monolithic bridge deck made of prestressed concrete. The cross section of the bridge deck is designed as an asymmetrical box girder, suspended on one side by a pylon. The pylon is located on the inner side of the bridge deck at the junction of the apex and the centre of the circle and is anchored by hinges to the subgrade.

Continuous box girder bridge
Hajnoš, Mário ; Páleník, Petr (referee) ; Koláček, Jan (advisor)
The topic of this thesis is detailed design of supporting structure of continous box girder bridge across a deep valley called Lazný creek. The bridge have to pass the second class road with category S 9,5. The design is processed by two options. The chosen option is designed as a girder with five spans 44,8 m + 55 m + 55 m + 55 m +44,8 m. Total length of bridge is 268,57 m, the main girder is gradually cast into the formwork suspended on a special ceiling scaffolding. The axis of the bridge is in a plan straight with the constant transversal slope 2,5 %. The thesis contains six models in software SCIA ENGINEER. Part of the work is situated on time depended analysis with construction phases. Assesment of ultimate limit states and serviceability limit states were done by hand according to the valid standards and regulations. Structural analysis, drawing documentation and vizualization are parts of this work.

Box girder bridge
Vostal, Lukáš ; Pecha, Jakub (referee) ; Nečas, Radim (advisor)
The subject of this thesis is the design of a prestressed box girder construction with several spans. Two variants are designed and for detailed solving was chosen the variant of the box girder. The length of loadbearing structure is 212 m, the longest span has 60 m. The calculation of load effects is done by software Scia Engineer 19.1. Drawing part is done by software Allplan Engineering 2021. The thesis includes drawings, representation of the construction proces, visualization and a structural design. Designing and assessments were made according to currently valid European standarts.

Prestressed bridge on the expressway
Juřenčáková, Jana ; Zlatuška, Karel (referee) ; Koláček, Jan (advisor)
The purpose of the diploma thesis is to design a expressway bridge over the river Vsetínská Bečva. The bridge is located between Valašské Meziříčí and Vsetín. Separate superstructures are designed for each directions of the expressway. The right superstructure, which is wider, is considered for detailed design. Two variants were proposed, A double T beam superstructure and a box girder superstructure. The three span box girder superstructure was chosen for the design. Spans are 48+65+48 m long. Two options of construction process of the superstructure were proposed. This bridge is designed according to the limit states, the influence of construction process is considered. Structural models of construction were made as a finite element model and a plate model. Structural analysis, drawings and visualization were developed.
