#### 3.1.5 Eindhoven University of Technology's Full-Scale Measurement Program
They observed that the wind tunnel and the full-scale mean and fluctuating wind pressure coefficients matched well at almost every monitoring location on the roof, but the peak negative pressure coefficients obtained from the wind tunnel were generally smaller than the corresponding full-scale data. 3.2. High-Rise Buildings  
3.2.1. [PERSON]'s Full-Scale/Model Test Comparisons  
In the early 1960s, [PERSON] et al. measured wind pressures and structural responses for several high-rise buildings located in downtown areas in Canada that experienced strong ABL winds and compared the full-scale measurement results with the corresponding model test data. The first full-scale measurement campaign was undertaken on a 34-storey office building in downtown Montreal. In 1967, [PERSON] et al. [25] reported simultaneously recorded wind pressure samples, ranging from 15 min to 1 hour, taken from twelve wind pressure transducers arranged at two levels on that building. The mean pressures, pressure variances, spectra, and cross-spectra obtained from full-scale measurements were compared with the preliminary results from wind tunnel experiments in cooperation with the University of Western Ontario. It was found that the statistical properties of full-scale wind pressure fluctuations could be reproduced using model complexes placed in a boundary layer wind tunnel. In 1969, [PERSON] [26] completed the wind pressure measurements over a 4-year period on a 34-storey office building for the purposes of checking wind tunnel techniques. Comparisons were made on the mean and the fluctuating pressures, the power spectra, and the correlation between selected pairs of pressure values measured at various points on the building. Good agreements were found in general, but the comparisons showed some unsatisfactory correlations for certain wind directions. Several years later, another field measurement campaign was launched on the 57-storey Commerce Court Tower in Toronto. Wind effects and the wind-induced structural responses of that building were measured using pressure transducers, strain gauges, accelerometers, and displacement transducers. In 1975, [PERSON] [27] recorded simultaneous surface pressure measurements at 32 points on that building. The wind pressure samples were processed and compared with the corresponding model test data. The agreement between full-scale and model test mean wind pressures was satisfactory in general, but the level of agreement for fluctuating wind pressure coefficients was not very good. In 1978, [PERSON] and [PERSON] [28] measured the wind-induced movements of the same 57-storey office tower. They found that the observed building movements and wind tunnel results correlated well once the model data had been adjusted for building frequencies. In 1979, [PERSON] et al. [29] compared the full-scale wind pressure coefficients measured from that 57-storey building with the corresponding model test data. A good agreement was shown where sufficient full-scale data were employed. In 1982, [PERSON] [4] reviewed the earlier comparisons made between the full-scale measurements and the wind tunnel tests undertaken for the 57-storey office tower and supplemented them with new examples of a comparison between the full-scale and the model test dynamic behaviors. The comparison suggested that there might be little hope of predicting the full-scale behaviors to within about 10 to 15 percent in terms of relative error, even when the input data on which the model was produced were accurate. This is due to the reason that the field observations were subjected to so many uncontrolled variables. In 1983, [PERSON] et al. [30] presented the results from several years of observation on the accelerations of the 57-storey office tower under moderate to high winds. It was concluded that the full-scale and model-scale standard deviations of the structural acceleration correlated well for most wind directions.
