Analysis of static wind effects on the membrane canopy roof of a large stadium

This paper reports the results of wind tunnel tests used to investigate the spatial variation of wind pressure over a large cantilevered roof covered by a membrane. The dominant effect is development of large upwards suction. To prevent wrinkling, the membrane has to be prestressed. The paper reports options for pre-stressing and other methods which add to roof stiffness.
