스페리컬 탄성받침의 압축피로 특성에 관한 실험적 연구

초록

Could reduce the vibration of railway bridges in the Spherical Elastomeric Bearing target compression fatigue tests were conducted. Compression fatigue tests of specimens used in the design load 500kN, and two million cycles were repeated compression. In addition, before and after compression fatigue tests were applied to measure the compressive elastic modulus. As a result, the compression fatigue test before and after the compression modulus increased approximately 4.23%. Compression fatigue tests were observed during the appearance of specimens, such as cracking and tearing of panel disfiguration or permanent damage did not occur.
