Stanovení potřebného množství hasiva pro hašení objektu s hořlavým konstrukčním systémem

Abstract

This bachelor’s thesis examines the impact of a building’s combustible structural system on the amount of fire suppressant required to extinguish a fire. This study focuses on a room constructed using CLT panels and compares it with a similar brick-built version. The theoretical section describes the specifics of wooden buildings in terms of structural design and fire development, the calculation methods used to assess fire development inside the building, and the principles for determining the required amount of firefighting water. The practical section is based on a computational assessment of fire development, the determination of temperature conditions, and the calculation of critical and optimal water flow rates depending on the duration of uncontrolled fire development and the response time of firefighting units. The thesis also includes an assessment of the impact of water application efficiency on the resulting amount of extinguishing agent. The results of the study show that a combustible structural system can lead to faster fire development and, at the same time, to increased demands on the water supply needed for fire suppression.
