Eliminate structural thermal brigdes
Tůma, Pavel ; Bažant, Zdeněk (referee) ; Perla, Jan (advisor)
The Bachelor thesis deals with the ways of eliminating thermal bridges in overhanging concrete structures using ISO-beams. The first part of the thesis presents a list of producers who provide ISO-beams in the Czech Republic, a comparison of products according to the transfer of internal forces, and the complete product list of ISO-beams by Schöck GmbH. The second part deals with the calculation of internal forces of particular balconies and design reinforcement.

Concrete structure of railway platform
Šimon, Jan ; Šulák,, Pavel (referee) ; Bažant, Zdeněk (advisor)
The bachelor´s work is has engeaged of the concept of a roof load-bearing construction of the railway covered platform. It is concernerd of a momolithic ferroconcrete scelet construction with a console panel. The weighting is put over to separate footing. The summary of the bachelor’s work is based upon dimenzation and designing elements of load-bearing construction accordance with ultimate limit state. Result of the each static calculation is design of armature .

Utilization of biomass for energetics
Bažant, Zdeněk ; Radil, Lukáš (referee) ; Macháček, Jan (advisor)
This bachelor’s thesis deals with processing and utilization of biomass energy in the power industry. There are described single types of processing of biomass. It is possible to find a comparison between countries in EU and other countries from all over the world as far as utilization of biomass is concerned. Another part of this thesis is the comparison of the main economics evaluations which are generally used for efficiency evaluation of planned projects involved in the power industry. Due to the rising prices of biomass and other kinds of fuel, there is a progress of prices of gas, biomass and coal for the last five years. The practical part is the evaluation of gas boiler exchanged for biomass boiler. The calculation is based on real data taken from invoice from heating season. At the conclusion there’s the general viewpoint on biomass and its development.

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.

Monolithic multi-storey frame building
Přikryl, Martin ; Šulák, Pavel (referee) ; Bažant, Zdeněk (advisor)
The final thesis is focused on the design of monolithic reinforced concrete ceiling slab and supporting vertical structures of typical floor of an administrative building. Calculation of internal forces is carried out in a computer software SCIA Engineer. Assessment is done according to Eurocode 2 (ČSN EN 1992-1-1).

Statical design of residential house
Svobodová, Barbora ; Bažant, Zdeněk (referee) ; Zich, Miloš (advisor)
The master's thesis deals with static analysis of selected reinforced concrete elements of an apartment building. Specifically solved are the reinforced concrete slab of above-ground floor, point-supported slab of underground garage, the most exposed column, staircase, load-bearing wall of shear core, external load-bearing wall and building foundation on piles. Load effects were calculated using the Axis VM 12 software. Design of foundation was solved in the Geo 5 software. The thesis includes shape drawing documentation of selected elements.

Prestressed membranes above circular and elliptical plan
Juchelková, Pavlína ; Hájek,, Petr (referee) ; Bažant, Zdeněk (referee) ; Fillo,, L´udovít (referee) ; Stráský, Jiří (advisor)
This doctoral thesis deals with suspension cable roof structures above a circular and elliptical plan. The methodology of analysis is based on a basic annular cable roof structure of an external diameter of 70 m. The roof structure is designed as a prestressed membrane from the precast panels made from lightweight structural concrete which are supported with the bearing and prestressing tendons that are radially led between the two peripheral rings. The structural arrangement and the process of construction are described. The static system is specified and the terms like self-anchored system or equilibrium state are also defined. Finally, the results of static analysis are discussed in detail. The main aim of the doctoral thesis is to design a roofing of football stadium terraces using the structures of a basic annular cable roof; and present two alternatives – above circular and elliptical plan. The circular alternative comes directly from basic annulus, only the main dimensions of the new-designed structure are correspondingly extended. The elliptical alternative is an alteration of the circular design. As the radial tendons are anchored to the flexible peripheral curved girders, and the structures form the self-anchored system, the horizontal tendon forces load the peripheral girders radially. Because of that, it is essential to design a state of stress in tendon to prevent the undesirable global bending moments on the peripheral girders, and subsequently large non-uniform horizontal and vertical displacements of structure. Therefore, a study of the optimal load of ellipse is carried out. On the basis of the study, two basic requirements to structural arrangement of the elliptical roof are formulated. To illustrate the importance of a correct design, the optimal and unsuitable structural arrangements are compared. Finally, the results of static analysis of the circular and elliptical roof are again discussed in detail.

Monolithic multi-storey wall building
Vymazal, Jakub ; Šulák, Pavel (referee) ; Bažant, Zdeněk (advisor)
Final thesis with tittle: "Monolithic multi-storey wall building" is processeed as a project documentation according to valid assesment. The object is located in the city of Boskovice, 35 Hybešova street. Its ground plan dimensions are 52,8m x 12,5m. Total height of object is 22,3m including roof-wall, measured from the level of base chink. There are enclosed balconies on the south direction. Movement between floors is ensured by 2-flighted stairs. Object is It is made of reinforced concrete. It is designed as 6-floor bulding with a flat roof. The main supporting construction is created by system of walls and reciprocally asigned ceilings, which are sticked together. Walls are designed as pillars. The building is assigned to a belt bases. Module dimensions are 8,7m in longitudinal direction and 5,2m in transversal direction. Height dimension is 3,0m. The thesis is dealing with the 1st upper floor.

Static design of roof structure
Duda, Tomáš ; Bažant, Zdeněk (referee) ; Zich, Miloš (advisor)
The subject of the diploma thesis is the design and static analysis of roof structure. It is prestressed roof shell (membrane) supported by a cable. The whole thesis is divided into several separated units according to task's specification. The text section describes the introduction to the issue of presstressed suspension cable constructions and displays their possible shapes, types and realizations. There is also technical report of solved shell, which was written on the base of the documents, drawn drawings and structural (static) analysis.
