Some modeling aspects in the nonlinear finite element analysis of cable supported bridges
TL;DR: In this article, a two-node catenary cable element, derived using exact analytical expressions for the elastic catenary, is proposed for the modeling of cables, and the cable element tangent stiffness matrix and internal force vector are evaluated accurately and efficiently using an iterative procedure.

Localization and veering in the dynamics of cable-stayed bridges
Vincenzo Gattulli,Marco Lepidi +1 more
TL;DR: In this article, the authors propose a finite element model of a cable-stayed bridge and show that a small variation of the mechanical parameters produces a flipping between local/global (cable/beam) modal shapes within the veering region.

Tangent Stiffness in Plane Frames
TL;DR: In this article, a tangent stiffness matrix is derived for planar framed structures that does not require any approximation beyond those used in the conventional beam-column theory, and its numerical evaluation appears to be routine.

Dynamic behaviour of a cable‐stayed bridge
John F. Fleming,Engin A. Egeseli +1 more
TL;DR: In this paper, the dynamic response of a cable-stayed bridge to seismic, wind and simulated traffic loads is discussed, and the analysis procedure which is used considers nonlinear behaviour of the cables, caused by the variation in sag with tensile force, and non-linear behavior of the bending members.
