Abstract
Examination of the safety about dynamic force has been investigated in many fields. However, the design method of the structure subjected to dynamic force is not yet established. Relationship between the dynamic load and the static load was examined through dynamic load test based on the deflection of beam. The experimental results indicated that the dynamic load generating the identical deflection is several score times of the static load. In addition, it was revealed the deflection of beam was proportional to not the magnitude of dynamic load but its impulse of the dynamic load.
