According to this condition, this paper will discuss some nondestructive testing techniques using in the civil engineering in details, including the multisensor data fusion technology, the effect of modeling errors on structure damage identification using artificial neural networks, the load responding technology and the new technology of ultrasonic testing.

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.
