Influence of connections between towers and floor beams in cable-supported bridges

Abstract EN

The purpose of this paper is to present the static analysis of cable-supported bridges taking into considerations the influence of connections between pylons and floor beams.

To reduce some causes of nonlinearities, this research has been done to choose a reasonable type of connection between towers and floor beams.

Three types of bridges having three, four, and five spans have been analyzed.

These bridges were suspension; cable stayed with radiating or harp shape of arrangement of cables.

Four cases of connections between pylons and decks are considered.

In the static analysis, the energy method, based on the minimization of the total potential energy of structural elements, via conjugate gradient technique is used.

The procedure is carried out using the iterative steps to acquire the final configurations.

The author constructed all computer programs used in the analysis.

The major conclusions, which have been drawn from the present work, are outlined.
