DYNAMIC RESPONSE TO WIND AND WIND CLIMATE OF THE LULING-DESTREHAN BRIDGE AT LULING, LOUISIANA. VOLUME I: OBSERVATIONS FROM THE 1984-85 PERIOD. FINAL REPORT

This report contains the results of measurements of the aerodynamic response and wind climate of the Luling-Destrehan Bridge across the Mississippi River at Luling, Louisiana. This bridge is the first large cable-stayed structure to be built in the United States. The data of this report were recorded during 1984-1985 and cover a range of wind speeds between one and 35 mph. Perhaps for the first time, systematic measurements have been made of the response of cable stays to vortex shedding and wake-induced forces. In addition, a first mode response of stays to either galloping or bridge deck motion has been recorded. Both of the displacements and stresses from these three sources are small in the range of wind speed monitored during 1984-85. Various parameters and spectra characterizing the turbulence at the bridge site were measured and found to be within the expected range of values for such data. This volume of the report also contains a tutorial chapter for those who are not familiar with such aeroelastic effects as aeolian and wake-induced vibrations, galloping, flutter and turbulence buffeting.
