Analyse the frame in Figure 1 using the Force Method, with the vertical reaction force at D and horizontal reaction force at E as the 'redundant forces' (i.e. the 'primary structure' has support D removed and Support E replaced by a horizontal roller). Draw the shear force, axial force and bending moment (V, N, M) diagrams. The flexural rigidity for each member is indicated on the diagram. 15KN A 2m EI 3m 2EI M E 4m EI 36kN/m I Sm ZEI Figure 1 Axial Force Diagram (N) C 6m EI Shear Force diagram (V) Bending Moment Diagram (M)
