Experimental Investigation on the Wind-Induced Pressures on C-Shaped Buildings
Monalisa Mallick,Awadhesh Kumar,Kanhu Charan Patra 대한토목학회 2019 KSCE JOURNAL OF CIVIL ENGINEERING Vol.23 No.8
The present work focuses on the outcome of experimental investigation of pressure coefficients on different faces of C-shaped building models. An extensive experimentation was carried out to obtain a pressure coefficient over the surface of the models of varying configurations, corner curvature and angle of incidence between 0° to 180° at an interval of 30° in a subsonic open circuit wind tunnel. Four different configurations of C-shaped models of varying curvatures were tested. The models were made of perspex sheets. The recorded data of pressure at the located pressure tapings enabled determination of pressure coefficient and the study of the variation of pressure coefficient on the surfaces with wind angles and corner curvature. It has been observed that the pressure coefficient at a location on a surface varies significantly with the angle of incidence and the curvature of the surfaces. Also, the extent of maximum and minimum pressure zones have been found to change with the curvature and the wind direction.
