Numerical Study on Dynamic Effects of Box Structure depending on Train Moving Load

초록

This paper is intended to, with precast concrete box structure which is expected to directly receive the train load, analyze the dynamic effect in systematic way at the section where the acceleration is expected by HSR train (HEMU) running at maximum test speed 430km/h. Besides, dynamic effect by train load was evaluated to monitor the behavior of underground structure and neighboring ground and perform the performance evaluation of trackbed and numerical analysis to evaluate the structural stability which will be affected by dynamic effect of train moving load. As a result, dynamic effect by train load appeared to be insignificant but vertical acceleration was relatively higher.
