The Multi-mode Par-ticipating and Single Parameter searching method(M-S method)is introduced briefly at first,and then the according pro-gram,which is used to implement wind-induced flutter analysis of long-span bridge using visual fortran based on M-S method in ANSYS,is developed by the authors of the paper.

Advances in research of wind-induced vibration of long-span high-voltage transmission line system;

Experimental study on wind-induced vibration inertial force for a high-rise building;

The wind-induced vibration analysis is studied based on the modal analysis.

In this paper,an aeroelastic model of an annular cantilevered roof of a stadium was successfully designed and manufactured on proper simplification of the similarity rules and based on the characteristics of the structure and wind induced vibration responses of such structures.

Safety and serviceability are in this paper preliminarily established for controlling wind induced vibration of long span bridges.

In order to study the wind induced vibration and modal of long span suspension bridges under large wind, the data of wind induced vibration response are got by the real time monitoring system of Humen Bridge.

The results show that the flutter critical wind speed can be significantly increased by mounting an upper central stabilizing barrier on the top surface of the upper chords of the transverse frames of the truss girder,and the flutter .

The variation pattern between flutter critical wind speed of bridge with flat box deck and wind yaw angle is significantly affected by wind attack angle.

Thus the flutter critical wind speeds are much lower and the bridge is more unstable during this period.
