ABSTRACT
For major projects, it is quite common for wind tunnel tests to be undertaken at several independent laboratories as a means of improving the reliability of the end results. Therefore it is advantageous if the laboratories involved can present their results in similar formats to allow for quick comparisons to be made. The structural properties are normally provided to the wind tunnel laboratory by the structural designer. For the purposes of the wind tunnel analysis, they are most conveniently in the form of the natural frequencies and deflected shapes of the lower modes of vibration of the building, as well as the distributions with height of the mass, and polar moments of inertia of mass. The wind tunnel laboratories undertaking the testing of tall buildings should have appropriate coordination and quality assurance procedures in place.
