Seismic Performance Evaluation of Railway Bridges Using Spherical Elastomeric Bearing

스페리컬 탄성받침을 이용한 철도교량의 내진성능평가

Railway bridge is the most problematic thing in the railway is due to noise and vibration. To solve these problems, there have been studies. However, a fundamental alternative to the noise and vibration. It has not so far not shown, and to minimize the problem is focused. As a result, developed a lot of noise reduction measures, but the vibration is not much for reduction. In this study, to support the superstructure of the bridge vibration possible for spherical elastomeric bearing is a technical review. And it applies to the railway bridge, the numerical analysis was carried out.
