Glass curtain wall is a contemporary new wall, it gives the most important feature of the building is the architectural aesthetics, architectural features, building energy efficiency and building structure factors unify buildings showing different colors from different angles, with the sun moonlight, lighting changes gives a dynamic beauty. In the continents of the world's major cities are built magnificent glass curtain wall construction, such as the World Trade Center in New York, Chicago Petroleum Building, the Sears Tower with a glass curtain wall. Bank of China Tower in Hong Kong, the Great Wall Sheraton Hotel Beijing and Shanghai Friendship Building, have also adopted. In the prevention of glass curtain wall works of the last century, built in the 1980s has been basically reached its design life span, but the majority of the glass curtain wall off, suddenly blew, did not take any precautions, there are security risks. Whether they can meet the requirements for safe use? If not, how to detect and how to take measures for reinforcing and strengthening, has been plagued by the problem of the engineers. In this paper, based on the the engineering structural dynamic detection theory, signal analysis method using the Hilbert-Huang Transform, the vibration transmission rate as the indicator of damage identification, the following research: Introduction to the basic theory of vibration transmission rate to be applied to the glass curtain wall frequency response function open plastic damage identification and comparison results show that: the frequency response function and vibration transmission rate can be applied to the glass curtain wall open plastic damage identification, vibration transmissibility in the frequency response function to some extent better than; introduced A new method of signal analysis - Hilbert-Huang transform, this method is suitable in handling non-stationary, non-linear signal, has been widely used in the field of earthquake detection, biomedical, marine platforms and structural health monitoring, and achieved many achievements, the simulations show that the Hilbert-Huang Transform for nonlinear and non-stationary signal analysis is feasible, has advantages compared with other signal analysis methods; against wind loads, the presence of seismic loading, and difficult to accurately measure external loads of new damage identification method is proposed without measure, and improve the damage dynamic measurement accuracy compared with the traditional method, this method does not need to measure external loads can identify structural damage, the injury parameter values ??response to injury size.
