The steel bars configured in reinforced concrete structures can be divided into the following types according to their functions:

1. Stress-bearing bars - steel bars that bear tensile and compressive stress.

2. Stirrups - bear part of the diagonal tension stress and fix the position of the stress-bearing bars. They are mostly used in beams and columns.

3. Erecting bars - used to fix the position of the steel hoops in the beam and form the steel frame inside the beam.

4. Distributed ribs - used in roof panels and floor slabs, arranged vertically with the stress-bearing ribs of the slab, to evenly transfer the weight to the stress-bearing ribs, fix the position of the stress-bearing ribs, and resist thermal expansion and contraction. temperature deformation.

5. Others - structural reinforcements configured due to component structure requirements or construction and installation needs. Such as waist bars, embedded anchor bars, prestressed bars, rings, etc.
