Hello, Just to make sure about No. of rebars point (b): The code says 4 rebars for rectangular and circular columns. Circular, not square.

" Keep Longitudinal reinforcement around 4%" -- Very true: In fact Indian Standard Code for Reinforced Concrete Design i.e. IS 456 encourages to give longitudinal reinforcement (both compressive and tensile combined) below 4% of gross area.

Thanks Akash! I think the US code should follow suit and lower the limit from 8% to 4%. The 8% limit is old and comes from when butt splices were a common practice in the US-this way even when you had columns with more than 4%, the bars were not too crowded because the splices would not have overlapping bars (they were butt welded).
