Simulation of Turbulent Wind Field for Tianxingzhou Bridge

The main bridge of Wuhan Tianxingzhou Bridge is a long span cable-stayed bridge with double towers and three inclined cable planes. It is the longest highway-railway combined cable-stayed bridge in China, which the main span is 504 m. The paper systematically recommends an efficient wind field simulation technique for wind-induced vibration analysis of long-span bridges. On this basis, the turbulent wind field of Tianxingzhou Bridge is simulated. Then the statistic characteristics of the simulated wind field are compared with their target correlation functions. A satisfactory agreement has been reached. This shows that the simulation theory is successful.
