Matějka, Libor ; Bura,, Roman (referee) ; Pěnčík, Jan (referee) ; Doc.Ing. Karel Kubečka, Ph.D (referee) ; Matějka, Libor (advisor)
This thesis deals with the optimization of structural details for flat single-leaf roofs. In the first part of the thesis, 3 groups of structural details for flat roof (flat roof parapet, gutter at flat roof without overhang of the roof cladding, intersection of the flat roof and vertical supporting structure) are characterized, classified and examined. In every group one of these structural details is designed with use of modern composite material based on secondary raw materials (still in development process). The theory describes the current issue of thermal bridges at constructions and applicable legislative documents. The next part introduces thermal engineering analysis (based on finite element method) of structures with annotated data outputs. The another main part of thesis provides with designed innovative optimization algorithm using multi-criteria decision analysis methods, which is then practically tested on the surveyed construction details. The conclusion summarizes the results and provides with improvements based on completed research.

Assessment of Reinforced Concrete Elements
Pecháček, Martin ; Šulák, Pavel (referee) ; Švaříčková, Ivana (advisor)
The aim of the bachelor's thesis is the analysis of internal forces design and assessment of the reinforced concrete loadbearing elements. Staircase, floor slab and window header of a detached house with supporting masonry walls are designed in the thesis. In the project of the floor slab the occur of a thermal bridge is taken into account. To prevention of thermal bridge are used systematic elements. To analysis internal forces on the structure Finite Element Method in the SCIA Engineer 19.1 software is used. The results of selected sections and selected load combinations are verified by method of replacement beams. Internal forces on the staircase are calculated by method of replacement beams.

Thermal measurement of the building
Kozák, Karol ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
Infrared measurements, as a method of contactless temperature measurement, has spread rapidly in various branches of industry. Nowadays, in era of saving energy and financial resources spent on building heating, it has become an inherent part of revisions and controls of excessive heat transfer over thermal bridges. The aim of this bachelor's thesis in it's first part is to describe the theory of infrared measurement and heat transfer of the building and the second part is focused on application of theoretical knowledge to evaluate the results of practical measurements of buildings A2, A3, A4 and A5 on Faculty of Mechanical Engineering, Brno University of Technology, which is regulated by the technical standard ČSN EN 13187.

Comparison of heat losses calculation by CSN 06 0210 and CSN EN 12831
Elcner, Jakub ; Šikula, Ondřej (referee) ; Košner, Jan (advisor)
The diploma thesis deals with comparison of heat loss calculation by CSN 06 0210 and CSN EN 12831. This work contains short introduction to the heat loss calculation, definition of basic terms, detailed analysis of heat loss calculation by both standards, description of exemplar buildings, heat loss calculation and heat requirement for heating of buildings according to particular standards. At the end of the work the comparison and discussion of calculation results is presented.

Particle Polymer Composite in structural details of the building envelope
Dostálová, Darina ; Lavický, Miloš (referee) ; Vokoun,, David (referee) ; Matějka, Libor (advisor)
Due to a European energy concept for reducing energy consumption and also the concept of sustainable development, there is a growing demand for reduced energy consumption during the operation of the building and hence increasing demands on the thermal and mechanical properties of the building envelope. For this reason, it is necessary to look for materials that could meet both thermal and mechanical properties, as well as mechanical resistance and loadability, especially for the application for the foundations of the house, the base of the house and for application to structural details for elimination of the thermal bridges between interior and exterior boundaries. The main motivation for choosing the topic of thesis was to find materials derived from recycled or secondary raw materials that would be suitable for manufacturing composite applicable for structural details in the envelope of the building and for insulating in humid environment. An economic and environmental aspect plays an important role in the choice of material. The main theme of the thesis is the laboratory manufacturing of a composite with a thermoplastic matrix derived from recycled plastic materials and waste foam as a phase. Has been developed a unique Waste-based Particle Polymer Composite (WPPC) made from recycled foam and polypropylene. However, before WPPC can be reliably used by construction designers, physical properties of WPPC must be accurately identified. Therefore, it was designed laboratory manufacturing system and sample testing system, it was studied thermal, mechanical, thermomechanical and moisture absorptivity of WPPC. Application of finished composite material with satisfying thermal insulation properties to structural details to eliminate the thermal bridge, was the next step. These are details of the unloaded, prefabricated balconies, windows, atics, as well as basement constructions and the heel of the central load-bearing wall, the terrain flooring and the staircase wall

Design of Reinforced Concrete Structure of Residential Building
Bodor, Andrej ; Strnad, Jiří (referee) ; Požár, Michal (advisor)
The bachelor thesis is focused on the design and assessment of the reinforced concrete floor structure and selected load-bearing structural elements of the apartment building. The design and calculation of internal forces was developed using SCIA Engineer 21.1 and subsequently compared with the manual calculation. Selected structural elements were designed and assessed for sound insulation and thermal bridge breaks. The design of the structures followed the applicable European standards EN 1992-1-1 and EN 73 1201. The final output is the elaborated drawing documentation.

Zhodnocení efektivity a návrh konstrukčního řešení pasivních domů z hlediska energetické a finanční náročnosti při použití materiálů dostupných na evropském trhu
PAVEL, Michal
The topic of the diploma thesis is an evaluation of the efficiency and a proposal of the construction solution of passive houses in term of energy and financial demands using materials available on the European market. The thesis is divided into two main parts. The first one consists of a literature research, which provides the necessary information not only about the passive standard as such, but also about the principles associated with its construction. The second contains a practical part, where a database of the most important details for each material variant is created, together with their workflows, individual summaries and price comparisons. The result of this work is an evaluation of the efficiency of self-help construction of passive houses.

Apartment building – selected design elements
Doupovec, Vojtěch ; Požár, Michal (referee) ; Perla, Jan (advisor)
The first part of the bachelor's thesis deals with the design of selected load-bearing elements of an apartment building, it is a balcony console, a prefabricated staircase and a ceiling structure above a typical floor. The second part is devoted to the assessment of the masonry walls of the building. The output is drawings of the shape and reinforcement of these load-bearing elements. The calculations were performed using SCIA Engineer 19.1, IDEA StatiCa and Microsoft Excel. The drawing documentation was processed by CAD software AutoCAD 2018 with graphic superstructure RECOC.
