2) Referring to Appendix " A 3" of your text and beam figure 7th
from the top and 2nd from the bottom, a Fixed-ended beam with
Concentrated load "P" at midspan.
a) P=Pu=97.33 kips and L-18 ft. Using Fy=50 ksi steel, design a
W18 section and specify its unbraced length Lp.
Hint: you may use the appropriate table from your text
Appendix.
b) Draw a figure of the beam and specify the placement of the
horizontal braces using an "X" on the compression flanges.
