The dynamic effects of wind-structure interaction have become
increasingly important in recent times for suspension bridges due to
their ever-increasing span lengths.
This thesis involves the computational simulation and experimental
measurement of flutter variables for comparison against flutter theory.
Through literature review it is ascertained that flat plate flutter
theory is increasingly applicable to modern day streamlined bridge deck
sections. The Theodorsen theory for streamlined bodies is solved
for a flat plate that is investigated experimentally within a wind
tunnel. The critical flutter velocity and structural motions are
identified from structural vibration measurement and are compared
against those predicted by Theodorsen.
The flow around the deck is investigated using helium-bubble flow
visualisation for determination of wake characteristics.
