Bridge formed by cell box girder across the expressway
Klein, Vojtěch ; Volák, Ondřej (referee) ; Nečas, Radim (advisor)
The aim of this thesis is to design a bridge over an expressway and a railway. There have been designed three alternatives. For detailed solving was chosen variant transferring directionally divided communication by two identical bridges, formed by a cell box girder. The thesis includes drawings, representation of the construction process, visualisations and a structural analysis. Designing and checks were carried out according to European standarts.

Bridge over the Senice river
Urbánek, Filip ; Velešík, Marek (referee) ; Panáček, Josef (advisor)
This bachelor's thesis deals with the design of a road bridge over the Senice river. In the beginning of the thesis there are designed three variations of the bridge. The variation with prestressed prefabricated girders with composite slab is chosen for more detailed assessment. Time-dependent analysis is taken into account in the structural design. Detailed structural design is made and selected parts of the construction are checked for ultimate and serviceability limit state by Eurocode. Detailed drawings and visualization are made as well.

Flyover bridge over the Bečva river
Pidima, Jan ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The thesis deals with a design of a highway bridge with multiple spans. The bridge is constructed for highway D1 and goes across the river Bečva close to the city Přerov. Two different solutions were carried out from which a solution with subsequently prestressed box girder was chosen. Static model and load actions were modelled in program Scia Engineer 2016.0. Design checks were done manually according to corresponding Eurocodes. Load actions from wind, uneven support settling and horizontal actions from transit were neglecte.

Bridge ower railway line
Prekop, Michal ; Russnák, Adam (referee) ; Panáček, Josef (advisor)
Diploma thesis is focused on a design of the road bridge of the category S7,5 in cadastral territory of a municipality Polanka nad Odrou. Three preliminary studies have been proposed. Box girder beam with a slant walls were selected for more detailed processing. Construction of the bridge is going to be build by time-dependent analysis on a solid formwork. The calculation of load is done by using computer software Midas Civil 19 v 2.1. and Scia Engineer 19.1. Selected preliminary was assessed according to the recent Europan standards.

Design of a prestressed concrete bridge on the road I/38
Valent, Matej ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The diploma thesis deals with the design of an additionally prestressed and horizontally curved bridge structure on the 1st class road. The bridge is located on the newly emerging southeast bypass near the Czech town of Havlíčkův Brod. Three variants of the main supporting structure were proposed, with the choice being a chambered cross-section with inclined side walls. The total span of the bridge, with a length of 273,0m, was divided into 7 spans. The thesis also includes the design of the construction sequence. An assessment of the ultimate limit state and serviceability was carried out. Visualization and drawing documentation have been prepared for the thesis.

Viaduct Mordava rokle
Ondřej, Václav ; Romportl, Tomáš (referee) ; Nečas, Radim (advisor)
The aim of this thesis is design of the loadbearing structure of a bridge. Out of two proposed variants was chosen prestressed girder deck of 5 spans. The bridge is built span-by-span in a formwork supported by launching girders. Calculation of load cases is made in software Midas Civil 2021 and Scia Engineer 18.1. The construction is evaluated considering the ultimate limit state and serviceability limit state. The design and evaluation were made according to valid standards.

Study of CP-violation at the Belle experiment
Červenkov, Daniel ; Doležal, Zdeněk (advisor)
We present a first measurement of time-dependent CP-violation in B0 → D∗∓ ρ± , where D∗∓ → D0 π. The analysis was performed using the final Belle dataset containing 772 × 106 B ¯B pairs collected at the KEKB e+ e− collider. Three D0 decay modes are analyzed, K∓ π± , K∓ π± π0 , and K∓ π± π∓ π± . Since the studied decay is a scalar → vector vector decay, three helicity configurations are present. Exploiting the helicity configura- tions via angular analysis, the time-dependent CP-violation parameters encoding 2ϕ1 +ϕ3 are obtained from the fit. 1
