Abstract
The main span of the Tianxingzhou Yangtze River Bridge is a steel truss girder cable-stayed bridge with a main span of 504 m. It was the first long-span high-speed railway cable-stayed bridge in China at that time. In its engineering construction report, the use of stiffness standards is described as follows: for long-span railway cable-stayed bridges, the stiffness standards of the existing railway bridge codes are no longer suitable for use, and the value of the stiffness standards is an important technical issue. It is necessary to analyze the dynamic response according to the specific structure and refer to domestic and foreign engineering practices and experience to determine.
