In order to provide bending structures rationalization for reducing the materials consumption, labor and power inputs, construction or renovation terms, the authors considered the possibility of utilizing the structures with external steel sheet reinforcement and concrete layer made from fibers of different types. Experimental researches of various authors, both domestic and overseas, have been analyzed during the preliminary investigations. As a result, the steel and basalt fibers were selected for further inquiry, proved their rational sizes, percentage to concrete mass in structures worked under thermal and force impacts. It was developed the algorithm and software, helps to determine the stress-strain state and carrying capacity of composite floor slabs with different end and load conditions. It was concluded the necessity of physical-mechanical and thermal physic properties clarification of heated fibrous concrete. The experiment planning was performed to obtain the temperature dependences of strength and modulus of deformation, thermal conductivity and specific heat capacity of fibrous concrete mix.
