This article deals with the features of the work and determination of the limits of fire resistance steel-concrete slabs at thermal power influences and hinged support. Along with the use of structures with external sheet reinforcement it is effective to add various additives into the concrete in the form of fibers. Using fiber can significantly improve the performance of the structure under force action. During the literature analysis it was found out that there is no practically data on the strength of fiber-reinforced concrete at thermal power influences. This stimulates new experimental and theoretical studies of fiber-reinforced concrete in case of fire.
