Using the loading diagram for the frame shown below, complete the following;

a$.$ Using the Portal Analysis method, determine the BEAM moments at each column$/$support at the

$2$nd FLOOR LEVEL. The analytical model is shown in the sketch below.

b$.$ USING Moment Distribution, determine the BEAM moments at each column$/$support at the $2^{nd}$

FLOOR LEVEL. The analytical model is shown in the sketch below.

c$.$ USING RISA$-2$D$,$ determine the shear, moment and axial forces in each member and plot the

diagrams $-$ annotate the diagrams to identify values along the member lengths. Determine

and plot the deflected shape.

d$.$ COMPARE and contrast the Portal Method analysis results, the Moment Distribution analysis

results, and the RISA $2$D results. In particular, compare inflection point locations, moment values

at supports, and the reactions plus EXPLAIN similarities or differences in the results.

ASSUME ALL BEAMS AND COLUMNS ARE FABRICATED FROM THE SAME MATERIAL.
