Abstract: Impact calculation problem of dynamic load was studied by using linear vibration theory based on considering the effect of damping. The function expressions for structural dynamical displacement, factor of dynamic load and impact time were derived by using the vibration equation. And the effects of structural damping on dynamic load problem were discussed and analysed.

Key words: damping|dynamic load|impact|vibration|calculation
