 Wind-Induced Vibrations on Tall Buildings and Structures

Typical projects:

  • Tall buildings and structures
  • Long span and other aerodynamically sensitive bridges
  • Long span and retractable roofs

RWDI identifies and solves problems related to:

  • Building motions
  • Bridge aerodynamics
  • Aeroelastic vibrations

RWDI resources include:

Wind Tunnel Testing

Wind tunnel testing provides detailed wind load distributions for use in structural design, predicts wind-induced vibrations and structural loads, identifies aeroelastic instability, and develops solutions to wind-induced vibration problems.

Instrumentation

Laser displacement transducers, force-balances, accelerometers, strain gauges, pressure transducers and spectrum analyzers assist in the testing process.

Full Scale Vibration Measurement Equipment

Custom-designed monitoring systems evaluate the response of structures to wind or mechanical vibrations.

Vibration Analysis Software

Software identifies eigenmodes of complex structures and simulates the response to forced vibration.

What RWDI can do for you:

Consultations / Design Reviews

Early in the design process, review information and provide recommendations regarding aerodynamic stability of structures.

Meteorological / Site Assessment

Assess wind conditions at the site including the impact of local topography to evaluate how they translate into the wind speeds and turbulence levels to be considered in the design.

Topographic Model Study

Evaluate the impact of local topography on wind direction, wind speed and turbulence intensities by testing a topographic model in the wind tunnel.

Sectional Bridge Model Study

Test model of bridge deck section in the wind tunnel to see if bridge will remain aerodynamically stable against flutter and vortex excitation over a range of wind speeds.

Buffeting Analysis

Conduct analysis to evaluate response of bridge and wind loads due to wind buffeting.

Aeroelastic Bridge Model Testing 

Test scale models of construction stages / schemes and / or the completed bridge to assess stability and wind loading of the bridge.

Cable Vibration Assessment

Assess susceptibility of bridges to wind-induced oscillations of cable-stays and develop methods of suppressing vibration.

Aeroelastic Model Testing

Test scale models of slender towers, tall chimney stacks and large span roofs to predict wind-induced motions and structural loads.

Field Monitoring 

Assemble hardware and software, commission the system and monitor the motion / vibration of structures to evaluate their response to wind or mechanical vibrations.

Expert Testimony

Specialists provide testimony at hearings and court cases.

Damping Systems

Our sister company, Motioneering Inc., develops conceptual designs and undertakes the detailed design of special damping devices to suppress wind-induced vibrations.
