Based on the analytical model of the generalized force spectra of the first mode of typical lattice towers in along-wind direction,simplified empirical formulae to evaluate along-wind dynamic responses of lattice towers under wind load are proposed in this paper.

Based on the analytical model of the generalized force spectra of the first mode of typical lattice towers in along-wind direction, simplified empirical formulae to evaluate along-wind dynamic responses of lattice towers under wind load are proposed in this paper.

The rules about along-wind response and across-wind response under vary wind speed and vary wind angles was given through the analysis of data of test.

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.

In order to analyze the contribution-significant modes and the mode coupling effects for the wind-induced vibrations,a Ritz-POD method is proposed for identifying the contribution-significant modes,which takes into account the vibration-participating ability of each natural mode,and the similarity between the mode and the spatial distribution of the fluctuating wind load.

Rcsearch on the analytical method for wind-induced vibration of long span cable-staycd bridge and its progress as well as its future development is discussed in this paper.

Many studies of membrane structures were focused on the form-finding, cutting patterns, static analyses and construction, rarely involved in the field of studying its characteristics of wind-induced vibration.
