FULL MODEL-SCALE COMPARISON OF SURFACE PRESSURES ON THE TEXAS-TECH EXPERIMENTAL BUILDING/

Wind characteristics for the Texas Tech University field site and four different flow simulations are discussed in order to evaluate the ful l/model-scale comparison of the surface pressures on the roof of the e xperimental building at this site. A total of 700 data records, each o f 15 min duration, are used to describe the wind characteristics at th e field site. These results are compared with those from the wind tunn el flow simulations at a geometric scale ratio of 1/50. The four simul ations were achieved with the standard spire-roughness method and with three modifications of this technique. The final evaluation of each s imulation is based on full/model-scale comparison of the extreme sucti on pressures observed on the roof near the leading edge for normal and oblique angles of attack.
