The aim of this work is the discovery of the peculiarities of the behavior of reinforced concrete monolithic frame building structures in fire conditions as a basis for evaluating their class of fire resistance by calculation. Object of research - the processes that occur under the influence of fire, the elements of monolithic frame structures. Subject of research - methods of estimating classes of fire resistance of elements of monolithic frame structures. The relevance of the work. Analysis of the death and injury of people and loss of property due to fire shows that one of the reasons a large number of fires associated with the restructuring of the public economy, restructuring of production and technological processes without regard to requirements of fire safety, and often their violation in the construction and reconstruction of objects. Given the high danger of fires today in the budget of all States allocate considerable resources to the prevention and elimination of fire hazard. Among the causes that increase social and economic losses during fires can be set on a substantial number of cases, when in buildings with monolithic-frame reinforced concrete structures do not comply with the requirements of normative documents on fire safety, in particular their resistance to fire. The situation is complicated by the considerable restrictions on the conduct of fire tests of such structures. There are known cases of fires, which had serious socio-economic consequences associated with the collapse of monolithic frame structures under the action of temperature effect of fire, it was a clear violation of the relevant statutory requirements. In the process, the following tasks were solved. Built design scheme of the exterior wall and the floor slab. Developed numerical algorithms for the implementation of the proposed calculation methods and test the results of calculations. Developed algorithms for calculations and obtained the corresponding results. On the basis of the results estimated class of fire resistance of external walls and floor slabs and installed in compliance with the requirements of normative documents. The results of the work are data on the fire resistance class of walls and slabs, as well as their compliance with the requirements of the building code to the studied structures.
