The plane rigid frame has the four displacement degrees of freedom indicated. Assume El = 36 and EA = ∞ for all members. Using direct stiffness, determine the global structural stiffness matrix. (Hint: To avoid performing any transformations, solve for k11, K21, K31, K41, K12, K22, K32, K42 first. Use symmetry to fill in K13, K23, K14, k24. Then solve for k33, K43, K34, K44.)
