THE APPLICATION OF THE QUASI-STEADY THEORY TO FULL-SCALE MEASUREMENTSON THE TEXAS-TECH BUILDING

Full scale wind velocity and pressure measurements at the Texas Tech F ield Research Laboratory have been used to evaluate the performance of the Quasi-steady Theory. As expected the pressure fluctuations deviat e away from the theory's predictions in regions of flow separation, al though the incorporation of non-linear terms improves the match. Signi ficantly, the area-averaged loads over substantial parts of the buildi ng have high correlation with the approach flow and the probability de nsity functions, as well as the rms and peak pressure coefficients, ar e well predicted by the Quasi-steady Theory.
