Based on the survey of existing highway bridges, there are a large number of flaws induced by moving vehicles. The most important cause of this phenomenon is the lack of design codes on dynamic performance of highway bridges to moving vehicular loads. The existing theory of vehicle-bridge interaction is reviewed. Then the home-code program VBCVA combined with finite element program ANSYS is introduced to analyze the problem of vehicle-bridge interaction. Also, the existing design indexes of dynamic performance are discussed, such as dynamic impact factor, deflection limit, and acceleration. On the basis of above theory and program, the framework of design on dynamic performance of highway bridges to moving vehicular loads is proposed.
