Title: Experimental Research on Dynamic Property of Long-span Continuous Box Girder Railway Bridge with High Piers
Abstract:By finite element software,the natural vibration characteristics and vehicle-bridge coupling dynamic response of Shuangliu Bridge were analyzed,which was a bridge with a main span of 108 m in Yichang-...By finite element software,the natural vibration characteristics and vehicle-bridge coupling dynamic response of Shuangliu Bridge were analyzed,which was a bridge with a main span of 108 m in Yichang-Wanzhou Railway.Its natural vibration characteristics,vibration mode and damping ratio were tested by pulsating method.With dynamic load test,its strain,displacement and acceleration time-history response were tested under the conditions that the train passed or braked on the bridge at different velocities.The test and analysis results show that,this bridge had enough vertical stiffness,transverse stiffness and strength,and its dynamic property was good,and the safety and stability were good when the train passed on it.Read More
