## 3 Performed Full-Scale/Model Test Comparisons
### Low-Rise Buildings
#### 3.1.5 Eindhoven University of Technology's Full-Scale Measurement Program  
With the goal of investigating the consistency between building pressures in full-scale and wind tunnel experiments, a field measurement campaign was launched at the Eindhoven University of Technology (2018, 2018). The test building had the dimensions of 44 m in height, 167 m in width, and 20 m in depth. The facade of the building was made of steel columns, with steel parapets and glass windows. The surroundings of the building were flat. For meteorological wind measurements, a 30-meter-high guyed mast was established 130 m westward of the main building. The top of the mast was at the roof height of the test building. Temperature sensors and cup anemometers were mounted at three levels on the mast. In addition, a direction vane and a sonic anemometer were placed on top of the mast. After taking measurements, [PERSON] (2018) compared the full-scale and the wind-tunnel wind-induced pressures on the windward and leeward sides of the test building; they found that the wind velocity spectra in the wind tunnel were shifted toward higher frequencies compared to the full-scale data. It was also noted that the full-scale pressure spectra attenuated faster than the full-scale velocity spectra, but this was not observed in the wind tunnel. The coherence of the pressures was identical for both the full-scale model and the wind tunnel in many cases. 3.1.6. Tongji University's Full-Scale Measurement Program  
In recent years, researchers from Tongji University constructed a wind engineering research field laboratory in Shanghai, China, which consisted of a low-rise building and two anemometer towers. The full-scale building was 10 m in length, 6 m in width, and 8 m in eave height. Its roof pitch could be adjusted from 0\({}^{\circ}\) to 30\({}^{\circ}\). Two wind pressure samples of ten minutes in length, respectively obtained at 0-degree and 20-degree roof pitches, were compared with those measured on a 1:30 scaled rigid model in a wind tunnel by [PERSON] et al. [7]. It was shown that the mean and the fluctuating wind pressure distributions were similar for the two experiments, but that there was a notable difference in the magnitudes of the mean and the fluctuating wind pressure coefficients between the two experiments. 3.1.7. Other Full-Scale Measurement Programs  
Besides the aforementioned full-scale/model test comparisons concerning the well-known benchmark low-rise buildings, other researchers have also conducted related studies [22; 23; 24], and it is interesting to learn that all these works suggest that the negative pressure coefficients measured on the roofs of low-rise buildings were underestimated in wind tunnels. In 1975, [PERSON] [22] compared the wind pressures measured on a single-family dwelling with data measured on a 1:50 scale model that was placed in a turbulent boundary layer. The results showed that the pressure spectra and the coherence of surface pressures obtained from the full-scale and the model-scale experiments agreed well with each other, but the fluctuating wind pressure coefficients obtained from the model tests were consistently low. In 1991, [PERSON] and [PERSON] [23] compared the full-scale surface pressures measured from several agricultural buildings with data from 1:100 scale models. Mean wind pressure distributions at mid-building length obtained from the two experiments, recorded under the wind perpendicular to the ridge line, were compared. It was shown that a very good agreement between results was possible, but, in local regions where separation and recirculation occurred on the windward roof slope, the model-scale experiments tended to significantly underestimate the suction data. This observation appeared to be dependent on roof pitch. In 2009, [PERSON] et al. [24] presented a comparison of the wind pressure coefficients obtained from one full-scale single-family home that had experienced a sustained hurricane with the results of wind tunnel experiments on a 1:50 scale model of that home.
