Abstract

The response of a mechanically attached waterproofing membrane system located atop a building on the island of Miyako at the strong wind during a typhoon in 2007 was measured. A waterproofing membrane was constructed atop the roof of a building, and the PVC membrane was fastened by fasteners at a pitch of 600 mm. The response of the wind pressure and the billowing height of waterproofing membrane were measured at the site of typhoon No.12. The maximum wind speed was recorded as 16.8 m/s. The waterproofing membrane was billowing and flattering at high wind velocity. As the wind pressure increased, the billowing height of the membrane increased. The values of these parameters were higher at the edges of the test specimen. The results measured on site had good correlation between the wind pressure and the response of the membrane system at higher wind velocity.
