The method presented is a modification of the deflection theory and is based on the recognition of each individual suspender with its tension and stretch, and the horizontal displacements of the cable panel points. The procedure, adapted to electronic computers, deals with the solution of problems for suspension bridges with simply supported trusses. It simplifies the study of secondary effects such as suspender inclination together with the resulting variation to the horizontal component of the cable tension, variable moment of inertia along the truss, the truss shear, elongation of suspenders, and tower motion.
