Reinforcement layout

When I see such a notation on the construction drawings, Ф8@100/200 – I’m not sure what the 100/200 refers to. Does it mean that the spacing between the stirrups is 100 or 200?
On the construction drawings, I see such a notation: Ф8@100/200. The numbers 100/200 likely indicate the spacing of the stirrups, with one stirrup every 100 units and another every 200 units!
I see this marking Ф8@100/200 on the construction drawings, and there are possible explanations for such a marking as mentioned by the original poster and those above; it’s best to ask the designer to get clarity!

Reply to 1# Yu Long: The spacing of stirrups in the reinforced zone of the beam is 100, while the spacing in the unreinforced zone is 200. The length of the encrypted area is determined based on the seismic resistance grade of the beam.
F8@100/200 indicates an encryption interval of 100 and a non-encryption interval of 200
It indicates a distance of 100 for encrypted areas and 200 for unencrypted areas
It indicates that the distance for encrypted areas is 100, and the distance for unencrypted areas is 200. Some people think this description is correct
Regarding the marking of stirrups in beams and columns, in the reinforced areas the specification is Ф8 with a spacing of 100; in the unreinforced areas it is Ф8 with a spacing of 200. If the person in question wants to know more details, they should refer to Atlas 101. I can’t remember exactly which one it is, but it’s not difficult – you’ll understand it after reading it once
