I had an interesting question the other day from a PHD engineer: Design a steel beam.
Sounds simple enough.
My approach is to check the section class (web thickness to depth ratios), check the moment capacity of the section, Shear, member strength, deflections - and you're done, on to...
In deep beams there is a code requirement to have no bar further than 300mm from a restrained bar. As far as I know, this is a crack prevention thing. So, for example, on a 600mm deep beam, you will need one middle bar.
From the detailing code, I gather that the bar diameter is determined by the...
