In many bridge design codes,dynamic effect of moving vehicles on bridges is taken into account using a dynamic impact factor to represent the increment from static vehicle loads.For example,the AASHTO LRFD Bridge Design Specifications (AASHTO 2004)suggests a constant value of 0.33 for dynamic impact factor.
