Research Abstract

This paper describes a water leak test of roof tiles. The 100 roof tiles were set up on 10 lines and 10 rows on the pitched roof in the downstream of the flow from the wind tunnel. The flow velocity was increased gradually from the low velocity to the high velocity, and the effects of the wind on the roof tiles were investigated by the water leak test. The experimental apparatus for the purpose of reproducing the wind and the rain was used. The situation of the water leak test was filmed by video camera. Two accelerometers were simultaneously used.
