A Note on the Approximate Analysis of Suspension Bridges

The so-called linearised deflection theory of the stiffened suspension bridge has received much attention in recent years due largely to Pugsley's work and is regarded as a satisfactory basis for predicting the behaviour of such structures. This note is concerned with the use of the principles of stationary potential energy and stationary complementary energy, respectively, for the purpose of the approximate analysis of suspension bridges by Pugsley's linear theory including the concept of coefficients of flexibility of suspension cables. The value of that concept has been supported recently by results obtained by Stephens with the aid of simple scale models. C.F.P. Bowen and T.M. Charlton
