Wind-tunnel study of the Weirton-Steubenville cable-stayed bridge
A section model of the proposed Weirton-Steubenville cable-stayed bridge was used in the wind-tunnel study. The freely oscillating section model of the bridge deck was studied to evaluate the aerodynamic stability of the bridge. Basic aerodynamic derivatives were extracted in smooth flow and were used to estimate the prototype bridge critical wind speed for the one degree-of-freedom (torsional) flutter. The amplitude of the vortex-induced bridge oscillation was also assessed. The bridge section model response revealed one degree-of-freedom (torsional) flutter instability occurring at a critical ...
