Definitions

  • Reinforcements for flat structures in reinforced concrete are usually made from steel reinforcement meshes. Often, one or more reinforcement meshes are provided both at the top and bottom in the flat structure, such that both tensile and compressive stresses can be absorbed in an optimum manner.
