Minimum and maximum reinforcement in concrete walls


The minimum area of vertical reinforcement in the wall should be 0.4% of the gross cross sectional area of the concrete and should be equally divided between the two faces of the wall.

The maximum area of vertical reinforcement should not exceed 4% of the gross cross sectional area of the concrete. Horizontal reinforcement equal to not less than half the area of vertical reinforcement should be provided between the vertical reinforcement and the wall surface on both faces.

The spacing of the vertical bars should not exceed the lesser of 300mm or twice the wall thickness. The spacing of horizontal bars should not exceed 300mm and the diameter should not be less than one-quarter of the vertical bars. If the vertical reinforcement exceeds 2% of the gross cross-sectional area of the concrete then links should be provided in accordance with EC2 – clause 5.5.6.

    Unlike the concrete columns where the minimum reinforcement is 1% and the maximum is 8%. You need to know if the section is column or wall from its width to depth ratio
