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 AB and girder BC 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 kips/in.² for all members.
