Vertical Gust Response Prediction of Cable-Stayed Bridges in Yawed Wind

Shozo Nakamura, Ken Nagamachi, Yutaka Kawai, Kichiro Kimura, Yozo Fujino, Hiroshi Tanaka
Synopsis :
A vertical gust response in yawed wind of two cable-stayed bridges under construction was predicted by applying a modified gust analysis method. Two effective wind velocities, i.e. the velocity component normal to the bridge axis and the component normal to the free end of the girder, were considered separately. Some aerodynamic coefficients of the deck were estimated from the aerodynamic characteristics of the flat plates with same aspect ratio. Comparison was made between the analytical and experimental results, and on the whole, the results agreed in both bridges. Consequently, validity of the approximation was confirmed and applicability of the analysis method was shown.
