Q$2)$ determine if the beam$-$column shown below is capable of safely carrying the applied loads. Given loads were determined using LRFD load combinaitons and bending moment diagrams were obtained from second order analysis. HEB$400$ beam S$275$ steel $(F=275$MPA $)$ are used. There are lateral supports at the ends only.
