- Abstract
- This paper focuses on the dynamic behavior of continuous beam bridge subject to moving train load. The train is modeled as a series of moving sprung masses and combined track-bridge system is modeled as continuous Euler beam. Track irregularity is regarded as trigonometric function on the top of the beam surface. By using the interaction force as the relationship of train and bridge, the equation of motion is derived and solved by Newmark-beta and Newton Raphson method. Results are verified two examples of moving trains on the bridge.
