Spacing limits for shear reinforcement shall be as follows:
(a) Spacing of shear reinforcement measured along the axis of the member, shall be equal to or smaller
than the smaller of 0.5d or 600 mm;
(b) Where the width of the web exceeds 0.5d the spacing between stirrup legs measured at right angles
to the longitudinal axis the beam shall be equal to or smaller than 0.5d or 600 mm but need not be
less than 250 mm;
(c) Inclined stirrups and bent longitudinal reinforcement shall be so spaced that every 45° line, extending
towards the reaction from mid-depth of member (i.e. 0.5d) to the longitudinal tension reinforcement,
shall be crossed by at least one line of shear reinforcement;
