The critical velocity v c of the crosswind resonance is determined by trying for a quasi-linear structure in which cable elements are replaced by tension-only spar elements,and calculational values are compared between the quasi-linear structure with tension-only spars and the nonlinear structure with.

In this paper, the probability of crosswind resonance of the International Fair Center in Xiamen is verified according to the mechanism of crosswind resonance, and the equations of the crosswind resonant response are derived.

Based on the mode-matching method and transverse resonance technique for dielectric waveguide,a hybrid method called the merging method of high modes is derived,and an equivalent network can be constructed.

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.
