As a consequence of the growing production and use of asbestos and inorganic fibres, measurement of their concentration in indoor air is of great importance. The relevant legal regulations require the measurement. Various methods were developed for the purpose, based on collecting airborne particles in capillary membrane filters and subsequent determination of their number concentration. Remediation of buildings with fiber-containing construction elements is an essential part of any reconstruction.

This article deals with the possibility of assessing the k-value of power plant fly ash using durability. For cement mortars with replacement of 10, 20 and 30 % of Portland blended cement with fly ash, compressive strengths, efficiency indices, depth of talc water seepage and depth of carbonation were determined for ages of 7, 28, 60 and 90 days. For individual cement substitutes, k-values were determined for a given age using the relationship between water coefficient and compressive strength. According to the results of the hardness tests, the determined k-values were assessed and the k-values that are safe for the use of power plant fly ash in the aggressive environment XC and XD were determined.

This article follows up on Part 1, which dealt with the theoretical knowledge of partial fire protection of steel structures. It focuses on experimental work and numerical models, supplemented by parametric studies. Experiments were conducted on four steel samples, each subjected to a standard fire temperature curve for 60 minutes. The samples were tested with various thicknesses of coatback to determine its impact on the thermal behavior of steel. Numerical models were developed based on the experimental data and used for parametric studies, which examined the impact of various variables, such as the length and thickness of fire protection, on the temperature at the junction of the beam and column. The results show that the thickness and length of fire protection significantly influence the thermal stability of steel structures and can be used to design effective fire protection measures.

This article focuses on the partial fire protection of steel structures and provides a theoretical review of current methods and materials used in this area. Various types of passive fire protection systems are introduced, including intumescent coatings and their influence on heat transfer between protected and unprotected parts of the structure. The article deals with analytical and mathematical methods for determining the thermal properties and fire resistance of the materials used, with an emphasis on those that undergo thermal degradation. This article offers a comprehensive view of the theoretical foundations of partial fire protection of steel structures and proposes directions for further research in this area, providing a basis for Part 2: Experiments, Numerical Models, and Comparisons.

The article is focused on the issue of traditional timber joist floor structures and floor compositions from the period up to the first half of the 20^th century. In building practice, we very often encounter these structures in residential buildings that are the subject of structural changes. During these interventions, the basic ideas of the original technical solution are not always respected and some physical parameters of building are degraded. The article describes the principles that were devoted to these types of structures in historical legislative and standard regulations and further in professional literature. The original historical solutions are presented on a practical example. In relation to building interventions in historic timber joist floor structures, current legislative and standard regulations are described, as well as examples of modern solutions and their limitations.

The article deals with the description of selected graphic-numerical methods used to determine the amount of daylight. The principle of derivation of these methods is explained and the principle of working with the relevant diagrams is described. Nowadays, we rarely see the use of diagrams in practice, but some professional software uses them either directly or at least in their graphical outputs.

The paper deals with the uniformity of daylight in living rooms. It investigates the effect of the way the size and location of the living space in the living room is determined on the uniformity of light.

The paper presents the concept of maintenance engineering as understood in the new European standard EN 17666:2022 Maintenance - Maintenance engineering - Requirements. The standard introduces maintenance engineering as a discipline that uses competencies, methods, techniques and tools to develop and support maintenance to ensure that (maintenance) item is able to perform its required functions in a safe, sustainable and cost-effective manner throughout its life cycle.

The article deals with daylighting assessment in habitable rooms according to the currently valid Czech Standard ČSN 73 0580-2 and according to the Draft Czech Decree on Requirements for Constructions. The case study investigates and compares the daylighting availability in rooms which meet the requirements stated in the draft decree.

The article presents the design of prestressed cable-net glass façades based on the ANSYS software. The suggested model is validated and verified using published tests and published models in another software and used for a parametrical study of façades with point-fixed (“spider”) fittings. The study embodies two dimensions of the net, a spectrum of stainless steel Macalloy single spiral strands and laminated glass panes of various thickness. The cable prestress was taken as 30 % of their design load in accordance with published recommendations. The design respects the valid European standards for glass and loadings in serviceability and ultimate limit states. The results present tables of deflections, glass stresses and cable forces.

The article deals with preliminary information on design of prestressed cable-nets supporting large glass façades. Described are façade components and examples of prominent realized façades. In the survey of primary publications the trend of experimental and theoretical approaches concerning design problems of these structures is presented (securing of necessary stiffness and load capacity, danger of a glass-cable-net connection failure, failure of anchors or loss of prestressing, dynamic behaviour during failures, blasts and earthquakes, temperature effects). In more details are described publications used in the follow-up Part [31] for validation and verification of the own numerical analysis and parametric studies of these façades.

Textile and leather wallpapers are an integral part of the interior of historic buildings. These types of wallpaper are specific in their construction, where they are stretched on wooden frames and form a membrane in front of the wall. Verification of diffusion properties is one of the steps to elucidate the thermal-humidity behaviour of these historical structures. Knowledge of diffuse properties is important for architectural and historical surveys and for the reconstruction of historical buildings. Based on this knowledge, we can assess other properties of wallpaper construction, such as moisture and microbial climate.

The prepared experimental program focused on the shear resistance of presstressed beams with bonded tendons needed to develop a parametric study, focused on the shear resistance of the designed beams.
