One of the key roles of the girder is to provide structural rigidity and temperature stability while effectively suppressing vibrations from the ground during accelerator operation. The Korea 4GSR girder is being designed to have the first natural frequency above 50 Hz to minimize the effect of the ground vibration. In order to maintain better mechanical stability, it is necessary to conduct research not only on the natural vibration evaluation of the girder but also on external vibrations to the girder structure. In this paper, we introduce the result of the harmonic analysis of the girder structure using the finite element method.
