Spacing of Reinforcement
26.3.1 For the purpose of this clause, the diameter of
a round bar shall be its nominal diameter, and in the
case of bars which are not round or in the case of
deformed bars or crimped bars, the diameter shall be
taken as the diameter of a circle giving an equivalent
effective area. Where spacing limitations and
minimum concrete cover (see 26.4) are based on bar
diameter, a group of bars bundled in contact shall be
treated as a single bar of diameter derived from the
total equivalent area.
The horizontal distance between two parallel
