$(2)32$ pts: Given a $45ft$ long girder beam, $(Fy=50$ Steel$),$ with both ends, A & B fixed $($Fixed$-$Fixed condition$)$ having a linearly distributed Factored load

$Wu=3\mathrm{.}587\frac{k}{f}t.$ See Hint blow.

a$)$ Select a W$18$x$??$ section to support the load

b$)$ Check the beams adequacy to be a "Compact Section".

c$)$ 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 $"x".$

d$)$ Use equation $(11\mathrm{.}9)$ in the textbook to check the adequacy of the web to carry the maximum shear in the beam.
