Hi hokie66, by link I mean shape code 51, so what I'm trying to ask is if we use H20 links shape code 51 at 400 centre what are of reinforcement would this provide per meter?!
Could somebody correct me if I'm wrong please, is the reinforcement area of a H20 link = 628mm2 i.e. 2 x 314,
From this I was wondering if a H20 link at 400centres was equal to 785.5mm2 or is it different because it's a link.
