Spacing of shear reinforcement (concrete beam: EC2)

For design in accordance with UK NA, EC2 Recommendations, Irish NA, Malaysian NA and Singapore NA the longitudinal spacing, sl between the legs of shear reinforcement is given by;

sl,min,u ≤ sl ≤ MIN[0.75*d, sl,max,u]

where

sl,max,u = the maximum longitudinal spacing specified

sl,min,u = the minimum longitudinal spacing specified

If compression reinforcement is required for bending, for design in accordance with UK NA, EC2 Recommendations, Irish NA, Malaysian NA and Singapore NA the longitudinal spacing, sl between the legs of shear reinforcement is given by;

sl,min,u ≤ sl ≤ MIN{MIN[0.75*d, 15*Φcomp] , sl,max,u}

where

Φcomp = the minimum diameter of the compression reinforcement

For design in accordance with UK NA, EC2 Recommendations, Irish NA, Malaysian NA and Singapore NA the transverse spacing, st between the legs of shear reinforcement is given by;

st ≤ MIN[0.75*d, 600, st,max,u]

where

st,max,u = the maximum link leg spacing across the beam
