The contribution dealst with the problematics of statical defects, or more precisely with the formation of cracks in the brickwork caused by the effect of technical seismicity. It further deals with the construction principles which can be used when designing reconstruction of buildings which are located within the reach of the effect of technical seimicity. The problematics of historical buildings and conservation areas is also mentioned.

For excessive wet masonry rehabilitation, except for other methods, the method of air cavities is used. These can be wall or floor cavities. The wall cavities may be situated either on the internal or the external side of the wall. From the height point of view, internal side cavities can be located under the floor or above the floor level. This contribution only deals with the cavities above the floor level. In the projection practice, the air cavities usually are designed only empirically. But it is necessary to carry out their thermal-technical evaluation for their correct capacity. The matter of the evaluation is the topic of the following contribution.

Computing models for structural behaviour and determination of traditional timber butt joints using analytical relations are presented in this paper. A component method is a base of the computing technique introduced herein. This method is usually used for steel joints design. The component method is based on dividing a joint into individual components. These are defined by partial joint component stiffness. An analytical solution includes a subsidence effect of wooden material in a close proximity of compressive loading. Analytical computation results are compared with the experimental outputs. A design procedure according to Eurocode 5 for a load capacity determination of perpendicularly loaded structural element is stated in the paper.

The intention was testing of several variations of mixture composition at the laboratory and also extreme temperature ambient. Assessing the suitability of the matrix composition was carried out by using both basic physico-mechanical parameters and then microstructural analysis methods (on selected samples).

Mandatory standard of building design – nearly energy zero starts for larger industrial buildings from 1^st January 2018. This will have a major impact, especially in the design of the building envelope. This article analyzes whether the current setting of requirements of this building standard is technically and economically achievable. Analysis is based on typical industrial building.

Utilization of fibre concrete in building structures, supported by technical standards in preparation, stimulates the development of methods for nondestructive analysis of its structure, crucial for mechanical properties, as fracture resistance under tensile loads. The paper presents an overview of available methods, based i) on image processing and ii) on measurements of electromagnetic quantities.

Design of building envelope, that means layers of so called boundary constructions; is the key procedure within the design process. It might seem that this step is crucial only for industrial buildings with low-energy ambitions or those that are intended for international environmental certification. This article is focusing on valid Czech legal requirements and also on the coming nearly energy zero standard of buildings.

U-value calculation of curtain walling is one from more difficult calculation in the civil engineering. In according to trend of increasing glassing surface of building envelope, the curtain walling has big influence on thermal behaver of buildings. This is why it is necessary to calculate the thermal insulation properties with special attention. This article focuses on influence of different local thermal bridges on curtain walling U-value.

This report presents a new method for designing composite timber steel-fibre-reinforced concrete slabs with unprotected secondary timber beams subject to fire, taking tensile membrane action into account. The FE-model consists of material tests, push-out shear tests and beam tests, which had formed a preliminary study. The FE-model represents the behaviour of the floor slab tested in experiment, together with a collapse prediction for the slab. The FE-model with characteristic material properties includes a safety concept based on the Eurocode standards, and is applied to define the fire resistance of various types of timber steel fibre-reinforced concrete flooring.

Energy efficiency of industrial buildings in not very common topic. However, the quality of design must be based on valid national legislation and technical standards. Task to achieve best energy ratings is more and more frequently laid on building designer and energy specialist directly from investor – developer.

This paper discusses the practical use of microwave technology in construction practice. Opinions on the use of EMW devices are not only among the general public quite different. From boundless praise, to the uncritical condemnation. The reason for this situation is the lack of awareness of experts and the public about what is and what is not possible to expect from this technology.The article conclusions which we reached on the basis of experiments conducted at the Faculty of Civil Engineering Brno and subsequently verified measurements in field practice. The aim is to provide basic information about how to use microwave technology. Their benefits but also the risks that this technology brings along.

This two-part paper deals with the topic of environmental effectiveness of buildings. The goal of the paper is evaluation of expected embodied environmental impacts related with a detached family house. First part of the paper describes the evaluated building and used methods. Seven currently common variants of load-bearing structures (walls and floors) are described and compared. Five variants include masonry, while the sixth and seventh variant includes cast-in-place reinforced concrete structures. The evaluation follows Life-Cycle Assessment (LCA) methodology according to ČSN EN 15978 standard. The results of the evaluation are shown in the second part of the paper. Under the specified boundary conditions the variant with ceramic masonry filled with mineral wool has 5–14 % lower environmental impacts than other evaluated variants.

Long-time study of fibre-reinforced concrete, i.e. a composite material with a cementitious matrix, whose structure is hardened by usually randomly distributed fibres (steel ones in the most frequent case), demonstrates good mechanical and other technical properties, which makes possible its utilization in bearing structures. This stimulates the development of methods, non-destructive or low-invasive if possible, for the analysis of its structure, which determines crucial mechanical properties, e.g. fracture resistance under tensile loads. This article, coming from research activities of the Faculty of Civil Engineering at Brno University o Technology, brings an overview of available methods, namely direct methods coming from image processing and indirect ones utilizing measurements of electromagnetic quantities.

The article deals with hot-air treatment of a historically valuable Rožnov town office, built in 1770, which was transported to the Wallachian Open Air Museum in Rožnov pod Radhoštěm in 1924 as the first building of the currently extensive premises of this national cultural heritage. The method of wooden structure hot-air treatment was used for the first time in the territory of the Czech Republic in 2010. It has been used in western European countries (especially Denmark and Germany) approximately since 1930. This comprehensive method is governed by the German standard DIN 68 800 – Part 4 [1] and it is especially used for historically valuable buildings where emphasis is put on the preservation of the original wooden structure attacked by wood-destroying insects, usually of the long-horn beetle family (Cerambycidae) oranobium beetle family (Anobiidae). The goal of the article is to explain the hot-air treatment method to professional public using an example of one of implementations.

Water vapour permeability is one of significant material properties. The value of water vapour resistance factor is necessary to know to be able to rehabilitate structures, mainly after floods. One thing is essential – to know what are the values of water vapour resistance factor of the used material to know how long the structure will take to be dried and users can come back to live there.

The natural radioactivity lives mankind throughout its development. The effects of radiation to some extent they can influence the evolutionary history of life on Earth. It is therefore important to determine what values the natural radioactivity would reach different locations of the world.
