Problem 12.34 Consider the frame shown in (Figure 1). The axial stress in a column is proportional to its distance from the centroid of the cross-sectional areas of the colum given floor level. In the special case of the columns having equal cross-sectional areas, the force in a column is also proportional to its distance from the centroid of the column areas. At a given floor level the shear at the interior column hinges is twice that at the exterior...
