For the semi-circular, three-hinged arch ABC, shown in Figure P12.23, construct the influence lines for reactions at A and C, and shear, axial load and moment at F. A uniform live load of 2 kips/ft is applied along the top deck girder DE, assume that the load acts uniformly on the arch through the vertical struts. Compute the reactions at A and C, and shear, axial load and moment at F using the influence lines.
