According to the experience of a chimney and academic analysis,the lock in range of across-wind sympathetic vibration is discussed,and the errors about this in Load Code for the Design of Building Structures(GB50009—2001) is analyzed.

The across-wind vibration of tall buildings is quite complex.

Because the across-wind dynamic responses of some high-rise buildings exceed the along-wind dynamic responses,the across-wind vibration would become the control factor of structure design.
