Computer Study-comparison of approximate analysis with an exact analysis.

(a) Use approximate analysis to compute the reactions and draw the moment diagrams for column \(A B\) and girder \(B C\) of the frame in Figure P13.20, and draw the deflected shape. Consider column bases are fixed.

(b) Repeat the computations with pinned column bases at \(A\) and \(D\).

(c) Compare the results with the exact analysis using a computer software. Consider columns \(A=13.1\) in. \(^{2}, I=348\) in. \({ }^{4}\); girder \(A=16.2\) in. \(^{2}, I=1350\) in. \({ }^{4}\). Use \(E=29,000 \mathrm{kips} /\) in. \({ }^{2}\) for all members.
