Outline of Final Research Achievements |
Most damage to houses and buildings in strong wind such as typhoon or tornado are caused by the impact of flying debris such as stone or sticks. In order to reduce the damage, the estimation of impact force by clarifying the aerodynamic characteristics of flying debris is required. In many cases, the flying debris has a non-streamline shape, i.e. “bluff-body”. Therefore, this study aims to measure directly the aerodynamic characteristics of bluff-body. A stand-alone measuring device was developed, and was built in a bluff-body modeled typical shape of flying debris, such as cube, plate and rod. These models were dropped from a stage in a dome located at 50m height from the ground with windless condition. The pressure, the acceleration and the angular velocity were measured, while capturing the falling motion of bluff-body by video camera. The measuring method with the proposed device in this study was evaluated by comparing with the image analysis of movie records.
