Abstract
The influence of tap location on the pressure coefficients measured is clearly higher for flat roofs without parapet and decreases with increasing parapet height. For buildings with no parapets, points very close to the roof edge at the corner may experience very severe suctions that would have remained undetected with a conventionally designed and instrumented model. On the other hand, such high suctions affect only a very small portion of the roof corner because of their high gradient of reduction with distance from the edge. The measured values are generally consistent with Standard provisions. For the low building, the stipulations are near the measured local suctions, but somewhat underestimate the area averated loads. For the talle building data show higher suctions than the provision for no parapets or low parapets.
