Stress-Strain State of Air-Field Slab made of Basalt Fiber Reinforced Concrete

This study examines the impact of aircraft landing gear on the airfield slabs at the time of landing and the resulting reaction in the runway pavement material, depending on the type of concrete used. Two materials were compared: classical concrete and special concrete with the addition of basalt fiber. As a practical object of the study, an airfield slab was chosen. The calculation was performed in the Ansys software package, using the WorkBench graphical interface. The fiber concrete structure was modeled by the built-in means of the Material Design module in Ansys WorkBench; a linear-elastic concrete model was used as the material matrix. The research showed that basalt fiber reinforced concrete products have higher strength characteristics. They have better compressive, flexural tensile strength, tolerate more elastic deformations, and can handle higher loads.
