Solve Problem by using a computer program.

For the rigid building frame shown in Figure P5–22, determine the forces in each element and calculate the bending stresses. Assume all the vertical elements have A = 10 in.² and I = 100 in.⁴ and all horizontal elements have A = 15 in.² and I = 150 in.⁴ Let E = 29 × 10⁶ psi for all elements. Let c = 5 in. for the vertical elements and c = 6 in. for the horizontal elements, where c denotes the distance from the neutral axis to the top or bottom of the beam cross section, as used in the bending stress formula σ = (Mc=I ).
