【 摘 要 】

Travelling mass due to its mass inertia has significant effect on the dynamic response of the bridges. This study is devoted to the study of the dynamic response the real steel railway bridge of the length Lb = 38 m for the single locomotive bogie mass load MLbg = 44 t (Ĺ koda 350) passing over the bridge with the speed v=65 m/s. The iteration method of the governing partial differential equation of the transverse motion of the bridge structure w(x,t) has been applied. The modal superposition method for the vertical bridge deflection w(x,t) considering the first mode j=1 was used.
