SOME CONSIDERATIONS ON DYNAMIC EFFECT OF HIGHWAY STEEL GIRDER BRIDGES UNDER MOVING VEHICLES

The dynamic effect of bridges under moving vehicles must be investigated to decide the impact factor in the rational design of highway bridges. This dynamic effect is defined as the dynamic factor in this study, and is distinguised between the dynamic factor and impact factor written by design specifications. The dynamic factor of single-span bridges under the equivalent vehicle load to design live load is calculated. Numerical examples are presented to obtain the information of the dynamic factor of highway bridges consolidated the multi-span continuous bridges and the single-span bridges. Finally, the dynamic factor based on the deflection response and bending moment of highway steel girder bridges is suggested by a function with the parameters of span number and span length.
