The aim of this paper is determination of selected strength characteristics of dowel joints in cement-splinter boards VELOX on the basis of destructive testing and application of these results into the fully probabilistic SBRA method (Simulation Based Reliability Assessment).
Implementation of the ventilation ducts is one of the ways how to reduce the moisture in the vertical masonry structures. Functional ventilation ducts provide air inlet and outlet, which absorb diffusing moisture from the rehabilitated walls in these ducts. This causes the reduction of moisture in the structure. The implementation of the ventilation ducts is associated with the worsening of thermal parameters of the rehabilitated walls. This paper compares three variants of structural solutions of ventilation ducts and their impact on thermal parameters of the rehabilitated structure.
Problematic of optimizing the selection of a suitable building material for reconstruction in the Czech Republic is a frequent topic. The paper reviews the methodology of multi-criteria evaluation of partition walls for the following criteria: the mechanical-physical, technological, economic, but also ecological. The multi-criteria evaluation methodology can be used at an early stage of construction, in the decision process of selecting the most suitable material variants for designing interior non load-bearing walls.
Glass facades are significantly affected by the internal microclimate, and because of their use in this way it is necessary to use the secure elements of glass facades. For this purpose, safety multi-layer glass is used, which should fulfil its function after the failure of their integrity. This article describes the experimental destructive tests that indicate the behaviour of multi-layer safety glasses, depending on the thickness of the individual layers of the glass composite. A part of the article is the analysis of the cracks of broken elements depending on their thickness.
Glass as a building material is quite used nowadays. In the Czech Republic, the glass is still considered only as a filler material; therefore assessment of them in terms of statics is difficult. This paper deals with the issue of designing of sheet of glass of railing in the Czech Republic. This article describes the process of bending tests of multilayer glass of comparable thicknesses and analyzes its behavior in terms of safety and maximum load.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
