Sort By:   

  Experiment-2: Pure Simulation - Simplified Bridge Model
Dates: November 09, 2010 to Present
Description: This is an experiment in pure simulation using Matlab/Simulink to investigate the performance of MR dampers in controlling highway bridges vibration. A highway bridge model with associated truck loading and control device application is developed. The...

  Experiment-3: Real-Time Hybrid Simulation with Simplified Bridge Model
Dates: January 05, 2011 to Present
Description: After verifying the performance of the MR dampers in controlling the highway bridges, large-scale real-time hybrid simulation conducted at Lehigh University NEES facility is used to experimentally verify the pure simulation results.

  Experiment-4: Real-Time Hybrid Simulation with Complex Bridge Model
Dates: March 10, 2011 to Present
Description: The experiments with simplified bridge model provided a lot of insight about the performance of the MR dampers in controlling the highway bridges vibration, however, it cannot capture the behaviors such as local deformations and out of plane behavior...

  Experiment-5: Low Velocity System Identification Tests
Dates: November 04, 2010 to Present
Description: The Large-scale MR dampers exhibit highly nonlinear behavior at extremely low velocities, as observed in this truck-induced highway bridge vibration application. Existing MR damper models do not adequately capture the observed behavior of low force permanent...
