Abstract
A rapid and accurate method of analysis for the preliminary design of the stiffening trusses of suspension bridges is presented in this paper. The method demonstrates clearly the related functions of the cable and the stiffening truss, emphasizing the fact that the former is the major structural element and that the latter is added to reduce undesirable grade changes. It is useful in. determining quickly the effect of variations in the proportions, chord sections, and materials of the stiffening trusses, of differences in loadings, or of changes in major dimensions of the bridge. The proposed method gives results at the center and quarter-points which agree closely with those obtained by the deflection theory. Typical computations for the Triborough Suspension Bridge, at New York, N. Y., accompanied by detailed explanations, illustrate the procedure.
