The article presents the results of experimental and theoretical studies of strength and deformability of steel-fiber concrete double-sided pre-stress slabs under the action of transverse loading. The simulation of such plates in the software complex LIRA-SAPR was performed taking into account the physical nonlinearity of materials.


In connection with the search for new high-strength materials with high deformation characteristics, materials are now becoming increasingly popular with the use of composite impurities. These materials include steel-fiber reinforced concrete, which is characterized by increased bending strength and high deformability. These characteristics are very important for modern construction, which is characterized by an increase in spans and a decrease in the weight of building structures. The use of large-sized elements in the form of plates, panels are economically proven. It is also proved that the use of biaxial structures is most appropriate. Therefore, the study of strength and deformation characteristics of double-sided pre-stressed steel-fiber reinforced concrete slabs is a rather actual and practically unresolved problem.
