Dynamic Instability Problems

Pp. 215-256 (42)

George T. Michaltsos and Ioannis G. Raftoyiannis

Abstract

This chapter deals with dynamic instability aspects of cable-stayed and suspension bridges. The technique for determining the instability regions of frequencies as well as the boundaries of critical frequencies based on the solution of Mathieu-Hill equations is presented in detail. In the cases examined, instability phenomena in pylons, bridge decks and cables are analytically presented.
