Beam Links Spacing
Beam Links Spacing
(OP)
Hello All,
ACI 318 specifies maximum spacing between links along the beam span,
however there is no specified value i could find for spacing of legs perpendicular to the span,what do you normally use and based on what?
Regards

RE: Beam Links Spacing
normally this is only an issue if your beam is much wider than its depth or if its primary source of load is axial. Can you give a bit more information on your particular situation?
RE: Beam Links Spacing
This is based on Eurocodes and the relative National Annexes and is given as st,max
RE: Beam Links Spacing
Any tension bar cannot be more than 150m from a vertical leg of a link perpendicular to the span.
Similar provisions exist in EC2.
RE: Beam Links Spacing
I normally provide one keep the spacing perpendicular to span around 300 mm as common practice but could not find any reference in ACI 318
RE: Beam Links Spacing
If I understood your post you mean that for a 40cm wide beam you would need at least an enclosing link and an inner link .
I believe the stmax=0.75d #9.2.2 EN1992.01.01 refers to the maximum distance of vertical links in the beam's width and not along its length.
