Hi, I'm in the UK and I'm looking for any example calculations to design web stiffeners for a crane beam. The crane beam is already in place and the client is looking to install a larger crane. The superstructure is adequate but the crane beam is failing on web buckling under concentrated...

Thanks very much for all your help. The slab is spanning two ways as it is supported on the walls of a square lift shaft. (but yes in essence it will only span one way) I have told the contractor to use a lifting beam as I had previously specified as the solution to using metal decking wasn't...

I have a two way spanning slab (metal decking), i contacted the metal deck company to ask if they can assess the deck for concentrated loads (the loads are hung from the underside of the deck - lifting eyes). The metal deck company said they can only assess the slab with udl's and i should...

Thanks for all your help. I spoke to SCI who have said that they have carried out a calculation on the torsional resistance of a channel with a plate welded to the bottom flange and it provides minimal additional torsional resistance and therefore it should be ignored. thanks again

Thanks, I've calculated the second moments of area for the combined section, I'll see if i can find anything on Salmon and Johnson. Cheers

I also need to work out the torsional constant and the torsional bending constant. thanks

Please can someone tell me how to calculate the shear centre of a channel with a plate welded to the bottom? I'm trying to work out the torsion on a combined section but finding it difficult to get the shear centre calc, thanks
