An evaluation method for determining the wind resistance of mechanically anchored waterproofing membrane systems is proposed which uses a straightforward test method to assess wind resistance of the membrane. To obtain basic data for wind resistance design of a waterproofing membrane system, two tests were conducted: a pressure test on a flat roof of a building and a wind resistance test using a ring type specimen. Tests on the membrane anchored to the flat roof showed that, as might be expected, the force on the fastener section increased as the wind pressure became higher. The test method which uses the ring type specimen had good correlation with results derived from the pressure test conducted on the flat roof membrane based on the behaviour of the waterproofing membrane. This test specimen when tested for wind resistance was fractured at 56 % the strength achieved in the static test. Finally, a method for the design of fasteners based on a wind pressure induced fatigue model was proposed in order to apply the results in the construction of a flat roof mechanically anchored waterproofing membrane system.
