Static analysis of a concrete outlet channel
Skalník, Stanislav ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The thesis deals with the static analysis associated with the outlet channel of the lock chamber. The basis for the work was the design of reinforcement using full-threaded prestressing bars and the drawing documentation of the existing condition. The aim of the work was to present the issues associated with the anchoring of the prestressing bars by cohesion in the existing concrete structure, in particular testing on test blocks in the laboratory to verify a suitable solution. Following the data obtained, to perform an analysis and comparison on models solved by nonlinear computation in ATENA Science software. Subsequently, the analysis of the model of the existing condition of the outlet channel section is also carried out by nonlinear calculation with the evaluation of its behaviour to extreme loads. This model is then supplemented with reinforcement using prestressing bars with application of the knowledge associated with the pullout test models. The model of the pre-stressed outlet channel section is thus a simulation of the design on the lock itself.

Arch bridge across the expressway
Vaněk, Štěpán ; Štefan, Petr (referee) ; Nečas, Radim (advisor)
The objective of this theses is arch bridge design over the expressway. Bridge is consist of bridge deck, which has three pillars and composite arc. The Bridge deck is on the edges fixed into the foundations and in the middle adherent on overhead cables. The bridge is carried by combination of strands and aerial cables mounted on reinforced concrete arch. Overhead cables are slant due to the transverse direction of the bridge in the longitudinal direction is in the direction of the arc. Model of the construction was made in a calculated program SCIA ENGINEER 2011. The designe is in accordance with applicable standards.

Calculation of Prestressed Concrete Beam
Vítek, Filip ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This thesis is focused on the description of the calculation of prestressed concrete beams. The introductory chapter discusses the bias and distribution of prestressed concrete. The second chapter describes materials used for the production of prestressed concrete and its characteristics. The following chapters describe the calculation of changes of prestressing and their effects on the structure, prestressing methods and a limit state where the prestressed concrete is controlled. A model example of calculation is shown in the last chapter.

Design of structure for football pitch
Popovič, Tomáš ; Sliwka, Pavel (referee) ; Zich, Miloš (advisor)
This diploma thesis deals with the static review of structure for a football pitch. It is crosswise prestressed reinforced sliding plate with variable cross section. Assessment of the elements was done according to limit states. Internal forces from the load effects were calculated using the SW SciaEngineer 2015.1. The elements were assessed by SW Idea StatiCa 6. The main outputs of this static calculation are drawings of the shape and drawings of the reinforcement.

Design of a Sports Hall
Konečný, Vlastimil ; Šulák, Pavel (referee) ; Švaříčková, Ivana (advisor)
Aim of the diploma's thesis is to design selectedelements of sports hall. It is a single-storey object, where the main structural system consists of a frame of columns and prestressed girder. Design of elements is done according to limit states. To determine the effects of internal forces is used computational software Scia Engineer 2008.Outputs from computational software are compared with simplified manual calculation. There’s performed assessment and reinforcement of selected elements. For each element are drawn production drawings and reinforcement drawings. There are also prepared drawings of parts of construction and foundation drawing. Design and evaluation is conducted according to valid standards. The proposed design meets the requirements according to the ultimate and serviceability limit state.

Static provision of castle
Kulla, Lukáš ; Bažant, Zdeněk (referee) ; Strnad, Jiří (advisor)
The aim of this final thesis was static protection for castle in Miroslavské Knínice. It was necessary to explore several respects and find signs of violation. Next analyze and propose suitable assurance of individual parts. Separe into the stages of construction and to consider the proposal in terms of ensuring the resistance of materials. Finally create a detailed documentation in the range suitable for performance. Based on engineering geology and visual survey was designed horizontal bracing prestressing cables at three levels. The first level "A" consists of a closed circuit of prestressed reinforced concrete passports, supplemented by the cross and construction of prestressed reinforced concrete passports. Next level "B,C" is used to secure the top of the building. Levels “B,C” are proposed using prestressed cable in spare cable channels.

Roof construction over scating ring
Pospíšilová, Lenka ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
This document describes the design of the roof structure for the dimensions of the rink. It was designed and evaluated three roofing solutions – steel truss structure, concrete arch with external prestress and prestress truss roof girder with concrete roof panel. One option was selected – prestress truss girder. This variant has been further developed. In the beginning was drafted several proposals geometry respecting the demands on the type of construction. Within the static calculation was created a mathematical model of the structure of the program Scia Engineer. Using this model were obtained values needed for the assessment of individual elements of construction and design assessment as a whole for the ultimate limit state and usability. According to the proposed geometry and opinions parts of the structure was drawing documentation structure as a whole and individual parts of the structure solved in this thesis. The last proposal was visualized structures together with the phases of the construction by program ArchiCAD and rendered by program Artlantis.

Suspension footbridge
Černý, Jan ; Kulhavý,, Tomáš (referee) ; Nečas, Radim (advisor)
The objective of this master's thesis is a design of suspension footbridge. The footbridge is suspended construction of stress ribbon by one span. The brick deck is supported on the edges and it is kept in a parabolic arc. The suspension cables are kept at two inclined levels. The model lengthways is implemented in the program ANSYS, by non-linear solution. The model crosswise is implemented in the program SCIA ENGINEER 2011. The design is according to relevant current standart.

Static securing of Ludslavice church
Kovalíková, Mária ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
This thesis is drafting static protection church horizontal pretension, especially at the level of foundations and walls. Furthermore, the design of a new increase the stiffness of reinforced concrete towers and other prestress. The role was also producing construction drawings for the design of static security.
