DETERMINATION OF DYNAMIC FORCES IN BRIDGES. PROVISIONAL PROPOSALS FOR THE DETERMINATION OF THE DYNAMIC FORCES IN THE METALLIC BRIDGES

The results of the measurements of stresses produced by the passing of test trains at various speed stages over 17 metal single track bridges and spans ranging between 2.85 and 60.30 m have enabled the D 23 Specialists Committee to propose a formula for dynamic stress calculation. The hyperbolic enveloping curve proposed has it field of application limited to spans exceeding 4.00 m. It should however be remembered that this curve concerns results obtained at speeds below 150 km/h and a range of static stresses limited to values not exceeding 832 kg/cm squared.
