| Research Abstract |
We manufactured an air-cannon, that is a missile-propulsion device, for the impact resistant test of cladding against windborne debris. A series of test was carried out to investigate the performance of impact resistant and the characteristics of failure. The performance of glasses, plywood and shutter was evaluated by the specification of ISO16932. Also we investigated into the existing specifications besides the ISO 16932 and discussed the applicability of these specifications to the strong wind damage in Japan. Especially, we focused on the performance of impact resistant of cladding against the roof tile which is the main cause of the damage by the strong wind in Japan. The device which can propel a roof tile was developed. The comparative test was done by the roof tile as missile and the compatibility with the specification of ISO16932 by the steal balls and the lumber as missile was examined. Finally a series of standard missiles for the impact resistant test of cladding in Japan was proposed for the use of a domestic standard or a guideline.
