Experimental
and analytical study of stay cable dynamic properties. Determination
of cable inherent modal frequencies and damping characteristics.
Experiments were phased to allow for the independent investigation
of the impact of cable dampers and cross ties on the damping
characteristics of the stay cables. Recently completed project. |

Long-Term
monitoring of wind direction, speed and turbulence intensity
in several locations on the bridge towers and deck. Study of
deck vibration as determined by long-term monitoring of deck
mounted accelerometers. Over twenty-two years of valid data
have been accumulated and are currently under analysis. Ongoing
project. |

Comprehensive
aerodynamic evaluation of the Deer Isle Sedgwick bridge. The
program involves aerodynamic section model studies in a wind
tunnel environment, analytical studies and simulation, full
scale measurements and long term monitoring. Retrofits were
designed and have been implemented, bridge is currently under
remote monitoring. Ongoing project. |

The
Luling Bridge in Louisiana was the first steel cable-stayed
bridge in the United States to be located in a hurricane prone
area. The research program involves aerodynamic section model
studies in a wind tunnel environment, full scale measurements,
analytical studies and long term monitoring of the bridge to
determine its aerodynamic stability and performance. The bridge
is currently under remote monitoring. Ongoing project. |
