AU members of the plane frame in Figure are A36 steel and bend about their strong axis when sidesway buckling OCCUTS. The girder is a W27 x 94. The left exterior column is rigidly connected to the girder, but the right exterior column is pinned at each end. Weak-axis column bracing is provided only at the column ends. For the factored loads shown, choose the lightest acceptable W14 for each column.
