The frame shown is subjected to lateral loads of 36 kN and 45 kN acting at C and D, respectively. The columns have cross-sectional areas as indicated in the figure. Use Cantilever Method. Compute the following:

a. Axial load of column 1

b. Axial load of column 3

c. Moment of beam 1 at joint C

d. Horizontal shear of column 2

e. Axial load of column 5

f. Moment at the
