The trend of the earth building material use is not only for plaster but also for the construction of buildings, as well as repairs of clay buildings, which also require the need to determine the load-bearing capacity of whole walls, not just bricks. The loadability of the walls and the influence of moisture on brick strength have been subjected to experimental investigation of SHS o.s. within the framework of the OP HRD project, the load-bearing capacity of the pillars was examined by FA and FAST staff within the BUT grants.

In the paper the refurbishment of riding`s hall roof structure is presented. The combined steel-timber load-bearing structure had visible and high horizontal deformations and the gable wall was pushed out of the building.In the frame of refurbishment the diagnostic survey, structural calculations of the original and the new stage of the structure and the proposal of refurbishment works were worked out.

It is expected that the new administrative centre of Lesy České republiky would be an exemplary demonstration of the use of wood, which will be used in the form of the building material or in which the importance of wood will be emphasized in another appropriate way. The paper is focused on a proposal that won the international architectural competition in 2016.

The article is focused on overshadowing of agricultural land by buildings. On this kind of land is not possible to apply the standard criterion according to ČSN 73 4301 Residential buildings that is suitable for determination of overshadowing of the recreational land. In that cases is necessary to use a far more complex calculations and predictions of overshadowing using combination with agronomical know how because in some cases is overshadowing of the crops even useful.

Wood and the materials on its basis fulfil the requirements of an ever-evolving and accelerating society. In addition to naturally grown wood, wood-based materials are frequently used as a basic material for production of furniture and for building constructions as well. Looking at changes in waste management, a significant shift from the waste to the circular economy can be observed. The valuable raw materials are kept in the production cycle instead of landfilling or burning. Wood and wooden products can be efficiently separated in waste management, reused and recycled. The so-called wood waste – old furniture, wooden pallets, window and door frames, demolition wood, used lumber, bark and other wood residues can be reused in particleboard production. Particle board manufacturers in the Czech Republic have adopted progressive waste management and currently use 60% of recycled wood into particle boards. A completed life cycle analysis (LCA) of OSB demonstrates that replacing of 50% of natural fibres with recycled wood has significant environmental benefits. The objective is to push furthermore on effective legislation to promote waste material utilization and thus lead to a more sophisticated waste wood collecting.

The paper deals with the experimental analysis aimed at function verification of fiber optic sensors (Fiber Bragg Gratings). The sensors are used for mechanical stress measurement in wooden load-bearing structures. Glued laminated timber beam with built-in fiber optic sensor system was mechanically loaded during two bending tests. The data obtained using the fiber optic sensors were compared with the results of reference measurement method and analytical calculation.

The magnitude of the load on the walls of tall wooden constructions can be assembled according to the existing standards according to the valid combination equations in several ways. There are differences between the results. Determining the appropriate procedure for determining vertical strength from construction in different parts of building preparation and comparing it with other options is the subject of this paper.

A light pipe prototype with a concentrating mirror parabolic head was tested for temperature profiles under solar radiation. The purpose of the testing is to find maximal temperature and estimate potential risks with overheating in the position of the pipe installation into roof structures and materials.

In many practical cases it is important to know the actual value of tensile forces in prestressed elements of civil engineering structures. Main conclusions from experiments which were carried out within verification process and in situ application of the new method for an experimental estimation of the tensile force are described in the paper. The method is suitable for new structures and especially for existing ones.

The article deals with a comparison of a room area size which is suitable for reading and writing according to two daylight evaluation criteria. The first one is the daylight factor which is determined under the CIE overcast sky model and it is traditionally used for quantitative daylight evaluations of buildings. The second compared evaluation criterion is the daylight autonomy which is one of new daylight metrics whose calculation is based on daylight illuminance values throughout the year and for a specific location.

The article describes the methods of the surveying data and documentation production. The documentation is used for the process of planning, realisation and reconstruction of transport, energetic, industrial, ecologic and public objects. The documentation is also used in the remediation process and the protection of the buildings and historical objects. In these processes, it is necessary to know the spatial dimension – location data, the location of these objects on the Earth's surface and shape and dimensions of these objects. The activities that lead to the realisation, reconstruction and remediation of building objects require a quality maps, photogrammetric images and geodetic models (3D models), which are mostly realised in a suitable interactive graphic PC system in 3D digital form.

Heritage care specialists in the repair and reconstruction of historical buildings prefer using of previous working methods and especially materials, sometimes too strongly. It is not always easy to satisfy their requirements, with regard to the problematic of static object state. It is necessary to find suitable compromises.

The paper deals with structural-technical survey of Scala cinema in Brno. It is a historic building completed in 1928. The main purpose of the diagnostic survey was passportisation of structure´s defects, determine the quality of concrete and reinforcement, assessment of defects and failures causes, evaluate the condition of the ceiling structure in relation to the considered reconstruction above cinema.

The paper deals with the principles of structure, function, use, disfunction and repairs of framework (part 1 to 5).

The mutual joint waterproofing aspfalt strips can in practice be done in different ways. But not everyone is the correct one. Also important is the width of the overlapping associated strips. We will deal with strongholds in the modified stress and oxidized asphalt strip and compare the strength of the joints. If the bitumen is used as additional waterproofing is necessary, select the types of bitumen sheets with matching suitable bearing insert. As a waterproofing type we should use the modified asphalt strip. The issue of reliability of waterproofing is associated with a high quality of work performed. This quality is affected not only the human factor, but also the technology used for implementation of waterproofing layers. Another influencing factor is the type of applied asphalt waterproofing strip.

Between 1975 and 1985, many gyms of T18 type were built in Czechoslovakia. These gyms were mostly intended for schools, specifically primary schools. The manufacturer of these structures was Bučina Zvolen. The index T18 relates to the span of the load-bearing structure which amounts to 18 meters. The ground-plan measurements are 18,8 by 41,15 m.
The gyms were designed as low-cost structures, which also affected the length of their useful life – 20 to 25 years. In the present, many of these structures are still in use even though they are over 40 years old. Since there has been no refurbishment of these structures to this day, they fail to meet any normative criteria, especially concerning the thermal protection of the structure. Due to unsystematic maintenance, defects have in many cases occurred on the load-bearing members. These can result in limits to the structure’s usage and eventually to its complete shutdown. Under some conditions, it is possible to lengthen the useful life of the gym and it should be in the interests of its owners to be able to continue using it. Based on the diagnostics performed on the specific structure in Želiezovce (Slovakia) and the data collected from other gyms of this type, the authors of the presented contribution have elaborated the static calculation of the load-bearing timber structure for the case of enhancing the heat insulation properties to meet the European standards.

The definition of what is a common part of a residential building is essential especially when modifying the building structures and eliminating defects that affect both a common part and residential units. How common parts are defined affects who finances the modifications and reconstructions of such structures and parts. The definition of common parts is based on the new Civil Code (No. 89/2012 Coll.) and on the already abolished Act on Ownership of Housing (No. 72/1994 Coll.).

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.

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.

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.
