Reinforced Concrete Tables
Reinforcement area reference tables for everyday RC design.
Ready-to-use reinforcement steel areas for columns, beams, slabs and walls, covering the typical bar diameters and spacings that come up in reinforced-concrete design. Includes a dedicated mixed-spacing table for when alternating bar diameters are used to fine-tune reinforcement ratios.
Rebars — Columns & Beams
Total reinforcement area Aₛ as a function of bar diameter and number of bars — for columns, beams and stirrup legs.
Rebars — Slabs & Walls
Reinforcement area per metre aₛ as a function of bar diameter and spacing — for one-way and two-way slabs and walls.
Rebars — Slabs & Walls (mixed)
Reinforcement area per metre when alternating two different bar diameters at the same nominal spacing.
