碩士 === 淡江大學 === 土木工程研究所 === 82 === Prominent among the wind-induced problems of the Cable-Stayed
Bridges have been flutter and buffeting, so the aerodynamic
effects and critical wind velocity for the Cable-Stayed Bridges
due to wind loads will be treated in this research. The main
purpose of this research is to present an empirically based
analysis method to predict the structural behavior of the
bridges which have not been tested in the wind tunnel. The
equations of motions in drag, lift, and torsional directions
are assumed to be uncoupled in the formulation. The aerodynamic
parameters used in the analysis are adopted from the past wind
tunnel tests. The structural model consists of beam elements
and cable elements which are used to model the deck, tower and
cables of the bridge. A parametric analysis is performed to
study the variations of the structural behavior due to the
changes of wind velocities and mechanical damping ratios. The
contributions of the models in each direction to the structural
response are also discussed.
