Routine Evaluation Test of Wuhu Yangtze River Bridge
摘要
Abstract
The first routine evaluation test was conducted in 2014 for Wuhu Yangtze River Bridge to evaluate its safety conditions. Structural stress, deflection, bearing displacement, cable tension, vibration amplitude and frequency were tested. Test results show that the main truss’s stress, mid-span deflection, bearing displacement are basically consistent with the 2000 complete bridge experimental test results, the bridge structure is normal and at a elastic working stage. The tested dynamic coefficients of stress and deflection are both small and the vibration indicators ( transverse amplitude, horizontal amplitude, natural frequency and acceleration ) met the requirements related to bridge inspection regulations.关键词
