FEASIBILITY OF UTILIZING HIGHWAY BRIDGES TO WEIGHT VEHICLES IN MOTION. STRAIN GAGES ON MAIN LONGITUDINAL MEMBERS
The available literature on weighing vehicles in motion and stress history studies on bridges was studied. Since measurements indicate a linear relationship between maximum stress and vehicle weight the idea of using a bridge as an in-motion weighing device is supported. The basis for the design of the weighing system is stated and a preliminary system design is presented. This system could be used for weighing vehicles in motion or accumulating strain and traffic history records on heavily traveled bridges. This report is the second in a series. The others in the series are: 75-33, Exotic Sensors on the Bridge Deck, Not yet available; 75-35, Strain Gages at Bridge Bearings, Not yet available.
