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
