This question is for advanced steel design.Question guide. $($ please use BS code for the design and please do the design with web stiffener. $)$A simply supported beam, $5$m long is supporting uniformly distributed dead and imposed load of $50$kN$/$m and $80$kN$/$m respectively. The beam sits on $150$mm long bearings at the supports, and both flanges are laterally and torsionally restrained. Select a suitable UB section $($with web stiffners of your choice$),$ and check web bearing and buckling at supports.$($Note: You are not required to check for bending, shear and deflection$)$
