This paper discusses a long time measurements inner surface temperatures of different construction methods during summer season. The investigation was carried out on test building location at branch Holzforschung Austria in Stetten – Lower Austria in years 2011 to 2013. Inner surface temperatures were measured for different used construction methods of timber and masonry houses in quantity 44 samples. In this paper are presented the most significance results of measurement. The samples of construction methods were divided by specific characteristics: construction, core insulation, internal cladding and colour of facade. The measurement values inner surface temperatures were processed by statistical methods.

In the paper the results of exceptional experimentation are presented, which focuses on the long-term loading of metal plate connected wood trusses. The uniqueness of research project is given by real dimensions of long-span samples and by the term of loading over one year. The aims of long-term experimentation were detection of two main parameters. The magnitude of additional deflections and time of load action needed for their development. In the paper the recommendations for producers of metal plate connected wood trusses and for structural engineers are mentioned. The purpose of that research project is to increase the safety and reliability of timber load-bearing structures.

The airtightness measurements of building are important for construction of low energy and passive houses nowadays. It is very effective method to control quality of building envelope and look up for air leakages. These defects of building envelope is a source of wasted energy, because conditioned air heated or cooled is what is leaking out. It is better to find and seal the air leaks, and keep that conditioned air inside.
This study deals with investigation of research sample – 69 family single wooden houses. This amount includes multiple measurements. The construction method of building envelope is based on timber frame. Family single houses are located in Slovakia and border Lower Austria. The year of construction varies from 2011 till 2013. Airtightness measurements were conducted according standard STN EN 13829 (2011). For this investigation, there was Q 46 Blower Door Test equipment used, manufactured by Retrotec Inc., USA. The investigation of airtightness measurements of building was processed by statistical methods. Outcomes are the expressed value air change rate at 50 Pa. The results are divided to a few parts by significance. The first part describes air change rate at 50 Pa dependdant on number of storey and shape of the tested buildings. In the next part of investigation there is significance of difference between method B and A compared. The most interesting part is presented by percentage frequency of air leakages through building envelope. Analysis confirmed improving requirements airtightness of building.

Failures of basement waterproofing is constatntly frequent subject of discussion among laymen and professionals. This issue is very topical especially with introduction of new materials. Paper deals with two groups of basement waterproofing failures, i.e. failures associated with building movement and failures caused by technological lack of discipline during concreting the basement. Both groups of failures are demonstrated by extensive photodocumentation.

The major contemporary trends in building industry can include the use of wood as a building material of construction. In the construction of wooden buildings were made significant progress recently. Development of diagnostic methods for existing wooden structure is important for the reliability of wooden buildings. The paper presents a methodology for assessing the quality of existing wood structures using the device RESISTOGRAPH.

The paper summarized the results of the research works dealing with the development of advanced cementitious composite materials with fibre reinforcement designed for antiterrorist systems. The effect of different randomly dispersed fibre reinforcement (glass, basalt, polymer and steel fibre of 12–55 mm length and their combinations) on physical mechanical properties of the composite and its overall blast resistance was evaluated. The developed material was used for the design of blast resistant litter bin. The final dimensions, geometry and composition of the layers were defined using the numerical simulations in LS-Dyna implicit/explicit solver. The blast resistance of the element was subsequently verified by blast tests on the real product.

Roof construction with mechanically anchored waterproofing sheets rightfully belongs to the most popular solution of roof structure not only in the industrial but also civil and residential construction. This is because of the speed of construction, small depending on weather conditions and often lower financial cost. But vera often there are lot of mistakes in this part of construction design.

Building of large logistics and industrial buildings started in the Czech Republic in the midnineties; its construction boom peaked in 2000–2009. The industrial buildings are built even now, at the time of significant recession in building industry. Some flat roofs of this type of buildings show many defects and need extensive repairs and overall reconstructions. The findings and experiences of these repairs show that it is often about system defects which will in time result in necessary repairs or general replacements of many roofs of the industrial buildings.

During the reconstruction works of residential houses the associations of housing unit owners have to make decisions according to their financial means. It often arises a situation when windows are changed and facades of residential floors are insulated by a thermal insulation. Skirting part of the building and the roof is often in seclusion interests. Subsequent roof insulation therefore brings a number of design and implementation issues. This paper describes the necessary structural modifications of the existing double-deck roof structure (i. e. cold deck roof) to single-deck flat roof (i. e. warm deck roof) and increased financial costs caused by successive structural modifications made without consideration of the follow-up.

The article describes the construction, design and architecture of the stairway. The stairway is a substantial part of the complete construction in multi-storey buildings, apartment buildings, single family houses and shopping centers etc. The article also describes the aspects of stairway safety.

The main need for drilling wood at construction is at work carpentry or concrete, sleepers etc. The market is a larger number of species of wood drills and orientation in the selection of the correct type is useful to know some of their properties. I repeat it and think about it, why drills sleepers manufactured in series.

Currently, we increasingly need to carry out construction modifications on objects which in view of their age could be basically considered as new-build buildings at which we did not expect such a requirement. In most cases these construction modifications are caused by failures or defects of roofs, especially operation roofs – terraces. The cause of failure is often a combination of several factors. The primary source of error may be already a design project and roofing solution and quality of realization of each roof layer and roof details or unsuitable climatic conditions during the implementation. A separate issue could be the problem of the poor quality of used materials. By interaction of these negative effects then surprisingly arise failures at objects which were realized a few years ago.

This paper deals with the determination of linear thermal transmittance for buildings with rounded shapes. Introduction deals with typlogy and examples of the buildings containing organic shape. Subsequently is described the theory of determination of linear thermal transmittance. It provides information applicable for buildings assessment in engineering practice.

Years of speculation about the correct windows installation finally ends. On May 1^st the new standard ČSN 74 6077 Windows and external pedestrian doorsets - Requirements for installation came into force. It is the very first implementing standard for this branch of construction. The standard is based on the technical standard information TNI 74 6077 and replaces it.

Safeguarding perfect labour safety should be a principal requirement respected by all parties involved in the building process in particular from the point of view of the variety of works performed and complexity of building industry conditions as well as with regard to individual risks endangering life and health of workers during the preparation and performance of construction works. As far as individual entities operating in the building industry (tradesmen, small, medium-sized and big building companies) are concerned, adequate attention to labour safety is usually paid big building companies, only, who have sufficient resources to address this complex issued in a systematic way. It was the difficult economic situation associated with a considerable decline of the building production what has recently forced many building companies to implement significant saving measures that could affect the labour safety, too. The paper should show an apparent link between the economic situation, saving measures and labour safety in the building industry and call attention to apparent risks associated with the circumvention or violation of labour safety rules in order to keep profitability and competiveness of buildings companies.

The article aims to familiarize the reader with the complexity of the issue of the protection of buildings against the effects of water, especially in the liquid state. Waterproofing of buildings, it is not only the protection of roofs, but also the substructure, ie that part of the building, which may, in some cases, be deep underground.
The most important moment is awareness of the fact that meanwhile repairing the roof waterproofing is always accessible, in case of the substructure waterproofing the accessibility is always very complicated and any of its repair is very expensive. From this it follows that the design and use of only one system without the use of other systems, both direct and indirect, is very risky and as such can not be recommended.

An overview of the structural behaviour of notched timber beams. Notching a beam at its end leads to a stress concentration at the corner of the notch due to the sudden change in the notched beam’s cross section. The concentration of tensile stresses perpendicular to the grain and shear and can lead to failure caused by the crack propagation from the notch corner. In addition, a review of the notched beams design according Eurocode 5, reinforcements, and the design example are included.

The contribution deals with particular causes of excessive damp of wooden constructions in objects of the civil engineering. It concerns for instance the matter of water condensation on the surface of wooden elements and on the inside of constructions that contain wooden elements, of incorrect construction design, of constructions with wooden elements and leaking water in places wth wooden elements.

The article deals with the determination of effects of heat radiation on the quality of the indoor environment in winter season, while insulating by double and triple glasses. Effect of radiation through the fillings of the panels and building structures has been evaluated on the basis of knowledge of the mean radiation temperature and operative temperature in the given indoor environment. Isotherms of mean radiation and operative temperatures for different cases of application of insulated glasses having different coefficients of thermal transfer have been presented.
