Question:

Computer Study—comparison of cantilever and portalmethods with an exactanalysis.

(a) Analyze the two-story frame in Figure P13.19 by the portal method.

(b) Repeat the analysis using the cantilever method. Assume the area of the interior columns is twice the area of the exterior columns. Assume the baseplates connecting all columns to the foundations can be treated as a pin support.

(c) Compare the results with an exact analysis using a computer software. Use \(E=200 \mathrm{GPa}\) for all members; for beams and interior columns use \(A=\) \(10,000 \mathrm{~mm}^{2}\) and \(I=50 \times 10^{6} \mathrm{~mm}^{4}\); for exterior columns use \(A=5000 \mathrm{~mm}^{2}\) and \(I=25 \times 10^{6} \mathrm{~mm}^{4}\).
