抄録: | Damage to buildings or houses in strong wind like typhoon or tornado are caused by flying debris such as roof tile in most cases. Measuring aerodynamic characteristics of flying debris is required to predict the motion of flying debris and to evaluate the impact for the wind resistant design of claddings and the reduction of damage to houses. This study aims to measure the aerodynamic characteristics of flying debris. Stand-alone measuring device assembled with microcomputer, three-axes accelerometer, gyro sensor, pressure sensors, SD card and small battery was built in three types of models of flying debris. These models were dropped from the stage located at 50m in the dome with no wind, and pressures, acceleration and angular velocity were measured, while capturing the motion of models by taking movies with video cameras and conducting image analysis. Based on the result of the measuring, the motion and wind force acting on each model was calculated. |
