“…However the foam concrete cohesion problem with composite fittings in the bending elements is not studied. Previously, we have obtained the foam concrete cohesion parameters of density 1200-1600 kg/m 3 with glass composite reinforcement, metal and basalt composite reinforcement [12]. This paper presents the experimental and numerical simulation results on cohesion modeling of the metal, glass composite and basalt composite fittings with foam concrete of their density 1200-1600 kg/m 3 in the bent elements.…”

The article presents the computer simulation results and real experiment of foam concrete cohesion with glass-composite, basalt-composite and metal fittings in bending elements. Numerical simulation of beams implemented with software package “Lira-SAPR 2013” using finite element method for modeling. For real experiment used bending beam test method according to ISO 10406-1:2015. As a result, the influence of the loading level and foam concrete density on the reinforcement slipping value and foam concrete cohesive strength with reinforcement in the bending elements. The foam concrete cohesive strength with glass-composite fittings meets the standard requirements, so it can be recommended for the foam concrete bending elements reinforcement. Verification of the computer simulation results with the real experiment data allowed to establish the efficiency of the used numerical model and revealed the need to use the cohesion parameters in the "foam concrete – reinforcement" system for foam concrete structures calculations in specialized programs.
