摘要：

This paper deals with the magnitude and the distribution of mean and fluctuating pressure coefficients associated with corners and edges on the top surface of surface-mounted rectangular prisms immersed in a variety of turbulent shear layers. The discussion of the observed pressure data includes its variation with the turbulence intensity, S(u)/U, and the azimuth angle, a, of the incident flow. In addition, roof pressure coefficients from 1150 and 1/100 scale models are compared with field data from the experimental building at Texas Tech University (TTU). Finally, some recommendations are presented for the reduction of the extreme suction pressures observed under the corner vortices. A companion paper by the same authors is in preparation which will emphasize in detail the variation of the roof-corner pressure distribution with prism geometry (primarily the prism height, H).
