고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.5-40

4.5-40 The plane frame shown in the figure is part of an elevated freeway system. Supports at A and D are fixed, but there are moment releases at the base of both columns (AB and DE) as well as in column BC and at the end of beam BE. Find all support reactions; then plot axial-force (N), shear-force (V), and moment (M) diagrams for all beam and column members. Label all critical N, V, and M values and also the distance to points where any critical ordinates are zero.
