Effect of Microwave Radiation on the Compressive Strength of Solid Ceramic Brick

Microwave radiation is widely utilized in construction practice, especially for drying building materials, remediating damp masonry, or sterilization of biotic pests that have infested building structures. The available scientific and technical literature reports that certain materials exposed to microwave radiation do not change their physical and mechanical properties, although this has not yet been adequately verified. This paper builds on many years of research in the area, adding to and refining existing information, providing new insights into the mechanical and physical properties of commonly available building materials that have been exposed to controlled microwave radiation, and comparing them with reference values. The experimental research on a set of clay brick samples is carried out using tests according to European standards, and it focuses on the effect of microwave radiation on compressive strength and water absorption. The experimental samples were compared to reference samples that had not been subjected to prolonged exposure to moisture and were subsequently treated with microwave radiation for dehumidification

Family residence

Předmětem této bakalářské práce je vypracování návrhu rodinného domu v Brně – Přízřenicích. Zadáním bylo vypracování projektové dokumentace pro provádění stavby. Objekt je dispozičně řešen ve dvou nadzemních podlažích a jednom suterénu. Nosný systém objektu je řešen jako stěnový za použití vápenopískových tvárnic KM Beta Sendwix v nadzemních podlažích a za použití tvarovek ztraceného bednění v suterénu. Stropní konstrukce jsou řešeny jako železobetonové desky, zastřešení objektu je pomocí ploché střešní konstrukce.The subject of this bachelor thesis is the elaboration of the design of a family residence in Brno - Přízřenice. The assignment was the elaboration of the project documentation for the issue of the building permit. This building is designed in two floors and one basement. The supporting system of the building is designed as a wall from KM Beta Sendwix sandstone blocks in above-ground floors and from lost formwork in the basement. Ceiling structures are designed as reinforced concrete slabs, roof of the building is designed as a flat roof structure.

Revitalization of multifunctional house in Uhersky Brod

Předmětem této diplomové práce je vypracování návrhu rekonstrukce polyfunkčního domu v Uherském Brodě. Zadáním bylo vypracování projektové dokumentace pro provádění stavby. Objekt je dispozičně řešen ve čtyřech nadzemních podlažích a jednom suterénu. Nosný systém objektu je řešen převážně jako skeletový z železobetonových sloupů a výplňového zdiva z CPP a nosných stěn z CPP. Stropní konstrukce jsou řešeny jako železobetonové průvlaky s žebry a nabetonovanou deskou, zastřešení objektu je pomocí kombinací plochých a šikmých střeh s různými krytinami.The subject of this diploma thesis is the elaboration of the revitalization of a multifunctional building in Uherský Brod. The assignment was the elaboration of the project documentation for the issue of the building permit. This building has four floors and one basement. The supporting system of the building is reinforced concrete frame with brickwork. Ceiling structures are from reinforced concrete primary and secondary beams with slabs. Roofs of the building are designed as pitched roof, warm flat roof and double–skinned roof.

Experimental Fire Resistance Test of Timber Structure

Wooden materials have many advantages for their use in buildings. There are many limitations for their use as with other materials. It's because of the mechanical-physical properties of natural wood. With the use of the wooden structure of the building, the fire load is increased and the requirements for the fire safety solution are stricter. The combustible load-bearing structure influences the design of the building in terms of its function, layout solution, structural materials, and fire safety equipment. The data of the behaviour of wooden materials in the event of fire are necessary for the correct design a timber structure with the required fire resistance. This paper is focused on experimental testing of timber structures exposed to extreme situations such as the effects of fire

Surface Condensation on Windows and the Possibilities of Its Elimination

The largest thermal bridges are formed at the window joints. As a result of the increased heat flux, the internal surface temperature drops below the air saturation point. A conductive material applied on the interior side can be used as a remediation product. The correct choice of conductive material, type of masonry, and type of adhesive can affect the actual performance of the preparation. Using Ansys Steady-State Thermal software, the window sill detail of a double-glazed window with a wooden frame was analysed at the connection joint of the glazing and the frame

Numerical Analysis of Crawl Spaces Airflow

Unlike Central Europe (specifically the Czech Republic), where crawl spaces are not very common, their use is traditional in Nordic countries. However, due to the microclimate within crawl spaces, summertime can be problematic. The relative humidity within a crawl space can reach values of up to 95% [1]. Various factors, including airflow, influence the microclimate of crawl spaces. This paper focuses on simulating airflow and air age in a naturally ventilated soil space in the Czech Republic using OpenFOAM software. The study involves monitoring internal airflow, surface temperature of the crawl space floor and ceiling structure, as well as air humidity and temperature
