An Influence-Line Analysis for Suspension Bridges
Long-span suspension bridges cannot be analyzed by using the usual procedures for elastic structures. Because stresses and deflections are not proportional to loads it is not possible to superimpose various loading conditions or to use influence lines in the normal manner. It is customary to integrate the differential equation of the truss deflection curve, obtaining expressions in terms of exponential or hyperbolic functions. The equation for the cable-tension component H is implicit, containing the unknown H in the exponential or hyperbolic terms. This equation must be solved by trial for numerous loading conditions.
