Abstract: The design of protected fire escape routes is a process in which a number of technical aspects that are set by Czech technical standards must be considered. The assessment of protected fire escape route's ventilated premises is subject to strict values, which when designed, or when created additionally, often force us to resort to specific measures, like a forced ventilation, enlargement of openings, which leads to expensive construction. This paper focuses on the use of so-called engineering methods to solve this problem, specifically the computational fluid dynamics method, which finds application in the revalidation of otherwise unmet ventilation criteria.

Abstract: Wood is a natural anisotropic material that is used in building construction because of the advantageous properties of wood. Speed of construction and the final price of the building represent the main advantages of timber houses. On the other hand, the main disadvantage of these buildings can be the low fire resistance due to the flammable properties of natural wood. There are many limitations for designing these kinds of buildings in the Czech Republic. The limitations are presented in the standards and laws of the CR. This article focuses on the comparison of the methods for testing structures using timber construction elements. The paper presents and compares experimental testing results of a timber structure’s fire resistance in a combustion chamber.
