| Abstract: | According to the theories of dynamic structural mechanics, the key response factors for impacting force withstood by the highway bridges are analyzed about the dynamic simplified model, and the defects in using calculation method for impacting force are determined. It is necessary for the designers to calculate the impacting force by using impacting amplified spectra. |
