A 406 x178 x 74 UB section in $275 steel is simply supported at Its end and spans a distance of 6m. It is required to withstand a character value of permanent action of 25 kN/m. and a character. variable action of 18 kN/m. The beam is fully laterally restrained. Check whether the proposed section is safe to withstand the design load (ULs) and check the (SLS).
