FEATURES OF DESIGNING OF CONSTRUCTIONS AND BUILDINGS FIRE RESISTANCE IN CONDITIONS OF COMBINED HAZARDOUS EFFECTS ACCOMPANIED BY FIRE

Concepts of combined hazardous effects (CHE) accompanied by fire and their types are considered. The analysis of additional hazards and dangers for people, buildings and constructions in conditions of CHE accompanied by fire is given. It is noted that the conception of complex safety is the scientific and methodical basis of designing of buildings and constructions fire resistance for CHE cases accompanied by fire. General approaches to designing of constructions and buildings fire resistance for CHE cases accompanied by fire are considered. The necessity to give a more precise definition and additions to norms, relating to fire resistance designing of objects, which would consider an additional danger of CHE accompanied by fire and corresponding features of designing of objects fire resistance in such conditions is shown.
