1. The problem statement, all variables and given/known data Several beams of 533 x 210 x 92 kg/m UB section in grade 5275 steel are used to support a composite floor slab. Each beam is simply supported with an effective span of L=6.50 m. (a) During construction, before the floor slab is cast, a temporary concentrated load P kN (not destabilising) may be applied at any position along the span of any one of the beams. From considerations of bending and shear only, determine the greatest design value of P that can be carried at the ultimate limit state. You may assume that, at the supports only, each beam is fully restrained against lateral movement and so the mode shape parameter k can be taken as 1.0. I have absolutely no idea what to do for this! If anyone could give me any help with the method/steps to take then I'd be very grateful. Thanks.
