Thanks both, very helpful. I've managed find some more space after speaking to M&E and the minimum concrete I now have is ~215mm. I've attached a sketch of what I think I'll do. I can now fit 2 vertical bars in. Unfortunately I don't have space between openings for a diagonal bar so it'll have...
I'm looking at a concrete upstand that I've been treating as a wall. It's about 1100mm tall, 200mm thick, and there are some openings of 1050x220 mm. Some of the openings are very close to a wall edge - leaving around 115mm of concrete from edge of opening to edge of wall. How would you go about...
Thanks for your replies. I'm actually not designing the beam, just checking the capacity. I've been using the 'compression steel not yielded' method, and used quadratic formula to find x:
(0.85*fc'*b*beta) x^2 + (0.003*Es*As'-As*fy) x - 0.003d'*Es*As' = 0
So using A x^2 + B x + C = 0
A = 21...
Thanks a lot for your reply. So I should be following the method laid out here in slides 29 onwards?:

Hello all,
I'm trying to find the capacity of a beam to ACI 318. Bear with me, I'm a BS/Eurocodes guide. Details of beam:
1000mm x 1000mm
50mm cover, 12 mm links, 25mm bars. 7 bars, top and bottom.
So As = As' = 3436mm^2. Here's as far as I've got with ACI method:
d' = 50+12+25/2 = 74.5mm
d=...
