Reinforced Concrete Frame - Design of Selected Part of the Building
Hardubej, Martin ; Zlámal,, Martin (referee) ; Švaříčková, Ivana (advisor)
The thesis is focused on an assessment of existing structures at the four-storey apartment building. The supporting system design consists of a monolithic reinforced concrete skeleton. The subjects of assessment are girders, columns, beams and continuous slab. Another part of the project focuses on the design for reconstruction of nonconforming elements, which are the girders and beams. The work includes the development of structural analysis and reinforcement drawings of reconstructed elements.

Effect of fly ash on the durability of concrete
Vašek, Tomáš ; Kulísek, Karel (referee) ; Hela, Rudolf (advisor)
Bachelor thesis consists of two parts, theoretical and practical. In the theoretical section provides basic information on the manufacture of fly ash, development and principle of High Volume Fly Ash Concrete and view on this type of concrete in the Czech Republic. Listed below are the world´s knowledge of conduct of durability and potential problems that can act on them. The theoretical part ends with summary of the utilization of fly ash in various areas of construction industry. In the practical part compares the characteristics of each recipe containing fly ash with recipe containing only Portland cement. Finally, is evaluation of results of practical part and influence on the durability of fly ash concrete.

Centre of Leisure Time Brno
Gallo, Robert ; Teplý, Vladimír (referee) ; Odvárka, Antonín (advisor) ; Štěpánek, Ladislav (advisor)
The Leisure Centre in Brno - part Kraví hora represents the object of variable disposition providing a multi-purpose use. The aim was to design the house where nobody can get lost, the user-friendly house with the plain meaning as far as interior concerns, but attractive from the outside, which was accomplished with the COR-TEN façade. The object of the building creates exterior entrance atrium which is utilizable by various forms. It is placed into a brand-new park, where it dominates the space and at the same time with its façade fits into the natural environment. The building is ´cut´ by hygienic core in the concrete finish. The disposition is thus divided into two brightened atriums surrounded by the space designed primarily for exhibitions, dance, singing, playing the musical instruments, dramatic art and drawing.

Palace Magnum - realization of gross substructure
Hrubá, Denisa ; Klempa, Lukáš (referee) ; Biely, Boris (advisor)
The aim of this thesis is the building-technological solutions of gross substructure palace Magnum. It deals with the most optimal propsal of technological procedures, working machines, itemized budget, schedule, check and test plan, equipment of construction site, occupation safety and last but not least closer transport relations. The most interesting will be to deal with cramped space building located in the corner gap site on the border of Brno's city center.

Design of the Timber-Concrete Composite Ceiling Structure
Válek, Jakub ; Horák, David (referee) ; Švaříčková, Ivana (advisor)
The reconstruction of existing houses is currently a frequent issue. This work deals with the possibilities of reinforcing wooden ceilings with the focus on ceiling reinforcement using an over concrete slab. This suggested ceiling reconstruction work is desirable from the point of view of the rigidity of the object in the horizontal direction. The work includes the proposition for the composite, according to various norms and their comparison regarding the economic side of the design. The work further provides a description of the experiment, its preliminary results and its comparison with the theoretical calculation.

Possibility of determination of rheological properties of fresh concrete by penetration needle
Driml, Martin ; Sedlmajer,, Martin (referee) ; Zach, Jiří (advisor)
This thesis focuses on the method of determining the rheological properties of fresh concrete with a penetration needle. An assessment conducted in this thesis aims at current methods of determining the rheological properties of fresh concrete in terms of theapplicable technical standards. These methods are compared with the needle penetration method. This method is characterized with it's simplicity and low requirements for measurement rechniques. Therefore it can be used directly on site without any problems.

Influence of Initial Conditions on the Modulus of Elasticity of Concrete for Bridges
Blažek, Michal ; Bílek,, Vlastimil (referee) ; Cikrle, Petr (advisor)
Beside the compressive strength of concrete, which is considered as the basic parameter parameter for design of concrete structures a modulus of the concrete elasticity should be set as well. This thesis deals with influences, which are acting on the concrete, particularly within the initial stage of its hardening (i.e. within 28 days after casting). Nowadays, when time is the most valuable factor, some knowledge is required about mechanical properties of concrete earlier than after above mentioned 28 days and to apply them advantageously. The concrete in initial stage of hardening is influenced by many factors that affect progress of the elasticity modulus during the course of the time. For understanding of these problems a literature search was performed, as well as the experiment demonstrating the effect of temperature on the modulus of the concrete elasticity. The effect of temperature on the modulus of elasticity of concrete in initial stage of hardening has not been intensively studied yet. Therefore, more attention is paid to it by this elaborate. The experiment investigated the static and dynamic elastic modulus of concrete, whose recipe is similar to one used for production of prefabricated and prestressed bridge girders.

Activation admixtures in concrete
Eger, Lukáš ; Hela, Vlastimil (referee) ; Hela, Rudolf (advisor)
The aim of my bachelor´s work is the summarization and focus on admixure concrete,and the active and inert admixure, which have some positive characteristies for fresh and hardened concrete. Theoretically, I tried to study the increase of their joining potential while this characteristic can be used by either chemici or mechnical way, their combination as well. I also Works on evaluetion of physically mechanical influence for fresh and hardened concrete that can up to 60 days old while the cement was partly substituted by admixure of different character.

Reinforced concrete skeleton construction
Prokop, Lukáš ; Ing. Ivana Laníková, Ph.D (referee) ; Šulák, Pavel (advisor)
The bachelor work is aimed on designing of reinforced concrete, monolithic, locally supported floor slabs and fire effects on concrete constructions. Ceiling construction is located on the first floor. Calculation of internal forces is carried out in the Scia Engineer software. There is prepared drawing of the shape and drawing of the ceiling construction. In addition there are mentioned examples of evaluating the effects of fire on concrete constructures.
