“…Long-span Bridges generally possess characteristics of large flexibility, lighter weight, lower damping, and the structural dynamic response is sensitive to wind [1] . With the increasingly growing of span of bridge , the reaction of bridge result in wind are more and more significant, and research of wind resistance on long-span bridge seems very necessary.…”

In the research on calculation of interaction of wind and structure, the key to the question is wind field numerical simulation. This paper introduces a practical wind field simulation method of long-span Bridge. The main bridge of Jintang Bridge was analyzed as engineering example, which is a cross-sea cable stayed bridge in Zhoushan of Zhejiang Province , and the linear filter method was applied to calculate along-wind and vertical wind field on main girder, MATLAB program also was adopted to simulate wind field of long-span Bridge. The results show that simulated spectrum is in better agreement with the target spectrum, which verifies validity of the method and correctness of the program.
