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

Full scale wind velocity and pressure measurements at the Texas Tech Field Research Laboratory have been used to evaluate the performance of the Quasi-steady Theory. As expected the pressure fluctuations deviate away from the theory's predictions in regions of flow separation, although the incorporation of non-linear terms improves the match. Significantly, the area-averaged loads over substantial parts of the building have high correlation with the approach flow and the probability density functions, as well as the rms and peak pressure coefficients, are well predicted by the Quasi-steady Theory.
