Do any tables exist for the strength of common mild steel sections, similar to those you get for trusses, centre point loads, evenly distributed loads etc?
Tata steel blue book gives you compression, tension, moment, compression and bending capacities for a variety of sections (ub, uc, rhs, shs, chs, angles etc.) based on specific buckling lengths. You will have to derive the internal forces based on the applied load however. It is Fairly straightforward to do once you’ve looked at it a couple of times though.
Center point loads on tube here http://metalgeek.com/static/deflection.php
Loads of others on that site that are good for a quick idea.
If you have the specs of the material there are plenty more calculators available.
Apart from whole books I haven't seen any simple tables. Probably because there are so many variables it makes a table impractical.
Cheers fellas, I’ll have a look at that link/tata steel. It was just for a general idea, usually you could anchor a ship from anything I make but it’d be good to have a rough idea of some accurate strengths.
