Abstract
For the last decades there emerged a vast number of buildings and structures erected with the use of sandwich panels. The field of application for this construction material is manifold, especially in the construction of fire and explosion hazardous buildings. In advanced evacu-ation time calculation methods the coefficient of heat losses is defined with dire regard to fire load features, but without account to thermal and physical characteristics of building envelopes, or, to be exact, it is defined for brick and concrete walls with gross heat capacity. That is why the application of the heat loss coefficient expression obtained for buildings of sandwich panels is impossible because of different heat capacity of these panels from the heat capacities of brick and concrete building envelopes. The article conducts an analysis and calculation of the heal loss coefficient for buildings and structures of three layer sandwich panels as building envelopes.
Highlights
Three-layer sandwich panels are well-known in the construction of various facilities
The time allotted for the evacuation of people in case of fire, largely depends on heat loss in the building envelope
In this article we attempt to determine the coefficient of heat loss from the hot gases in the sandwich panel
Summary
Three-layer sandwich panels are well-known in the construction of various facilities. Supermarkets, terminals, industrial buildings in the oil and gas industry are built using sandwich panels. It is necessary to consider separately the behavior of sandwich panels in a fire. This is due to their distinctive features. If the fire appears small thermal inertia of the panels
