Measurement Capabilities

SOH Wind Engineering and Svend Ole Hansen ApS have extensive experience in wind tunnel testing and in a wide range of field measurements. The main focus in the measuring assignments carried out over the years has been structural response (acceleration and strain) and wind parameters (wind velocity, wind direction, temperature, barometric pressure and humidity). Visualization tests have been carried out in the wind tunnel using helium bubbles, smoke, and glass beads.

Wind tunnel measurements

A wide range of wind tunnel tests are carried out on all kinds of structures and setups.

Wind environment

  • visual tests using helium bubbles, smoke, and glass beads
  • wind velocity measured by hotwires in specific points on the scale model

Wind actions on structures

  • response of scale model measured by a flexible balance
  • pressure on scale model measured by pressure taps

Wind actions on cable-supported bridges

  • static and dynamic tests with section models suspended using wires or springs connected to force transducers

Calibration of anemometers

  • standard calibration procedures include IEC 61400-12-1:2005 Annex F / MEASNET and a custom 4-26 m/s procedure
  • custom tests include threshold, tilt, and angular response
  • experience with cup, propeller, and sonic anemometers

Field measurements

Field measurements are carried out on all kinds of building structures in all environments. A typical application is investigation of wind-induced response of lattice structures and chimneys. The response of the structure is measured as accelerations and/or strains and the weather conditions are verified by contemporary measurements of wind velocity and wind direction. The measurements may go on for several weeks or months in order to investigate the structural response in different weather conditions.

Another typical application is monitoring of vibrating floors. Many office environments have comfort problems regarding vibrating floors due to human load. An effective and economic remedy to vibrating structures is often installation of Tuned Mass Dampers (TMD). SOH Wind Engineering and Svend Ole Hansen ApS have experience in development and installation of TMD.
