Given a $45$ ft long girder beam, $($Fy$=50$ Steel$),$ with both ends, A & B fixed $($Fixed$-$Fixed condition$)$ having a linearly distributed Factored load Wu$=3\mathrm{.}587$ k$/$ft$,$ Select a W$18$x$??$ section to support the load showing selection process, Check the beams adequacy to be a $$Compact Section$,$ Recommend the compression flange bracing distances so that the beam has the full lateral support. Draw a Figure of the beam and show the placement of braces with an $$x$,$check the adequacy of the web to carry the maximum shear in the beam and Use Appendix A$3,$ P$\mathrm{.}450$ to determine the maximum moment in the beam under the distributed load
