The report presents the results of an analytical investigation into the nature of the response of symmetrical three-span continuous concrete slab and steel stringer bridges to moving vehicles. Previously developed theory is used to evaluate all the parameters usually associated with the analysis of the dynamic action of highway bridges. Ranges of bridge and vehicle parameters are obtained from standard plans and specifications and from reports of field studies, but specific correlation of analytical results with any one field test is avoided. The bridge is idealized as a single beam with constant cross-section, and the vehicle is represented by two masses mounted on two springs with damping included. Interleaf friction, initial vehicle oscillation, axle spacing, vehicle speed and various sidespan to midspan ratios are some of the parameters considered. Results are presented in the form of charts, and simplified formulas of the bridge response are given in the conclusion.
