Concrete components can be reinforced or non-reinforced. If reinforcement is required, it can consist of rebars or mesh. The reinforcement is generally used to make the component capable of bearing more loads, as concrete can only absorb very limited tensile forces.
The main purpose of the longitudinal reinforcement (also known as main reinforcement) is to absorb the bending tensile stresses in the longitudinal direction of the main load-bearing direction of the structural component. The cross-section of the reinforcing steel ensures that the tensile forces due to bending with or without longitudinal force and, possibly, torsion are absorbed.
The longitudinal reinforcement is placed on the top and bottom of the plates or downstand beams. A symmetrical or radial arrangement is the rule for columns.
