Wind-induced vibration of a long span space truss structure

In this paper, characteristic of wind-induced vibration of a a long span space truss structure was studied. Wind tunnel test was conducted in a boundary wind tunnel, based on which displacement along Z direction under all wind directions are discussed, and vibrations of typical nodals are emphasized. It is shown that the upwards corner of the roof may course greater peak displacement in this area than that in other areas. On the other hand, modal vibration of part area may be much greater than that of others, which may enhance the danger of local wind induced structural damage of these areas.
