Abstract:

Discretization methods are widely used in the analysis and design of suspension bridges. However, the large number of variables involved do not normally allow examination of the influence of different parameters on the behavior of suspension bridges. This paper presents a numerical method of analysis of suspended cables under vertical loads. Both explicit equilibrium and tangent stiffness matrices are derived by the finite element method. The expressions are also presented in dimensionless form, so that parametric studies can be performed. The obtained matrices can be assembled easily in a general structural analysis computer program. The proposed method is applied to the simplified analysis of suspension bridges. Some dimensionless charts are given for a single span suspension bridge. These include displacement and bending moments under the position of a concentrated load, pseudoinfluence line of displacement and bending moments at the quarter of span, and maximum displacements and bending moments for an arbitrarily located distributed load. It is believed that these charts can be useful in the first phase of design of suspension bridges and can contribute to the understanding of suspension bridge behavior.
