The work research of two-layer combined reinforced elements in pure bending

Abstract

The experimental-theoretical studies’ results on the work of two-layer combined reinforced elements with pure bending are presented. The full-scale tests of single-layer and two-layer elements with combined reinforcement showed that the vermiculite-concrete layer increases stiffness and crack resistance by 15–20%. The proposed numerical method for calculating the bilayer elements on bending forces provides high convergence (95%) with the full-scale experiments’ results.
