Rapid development of science and technology to bring us not only the improvement of living standards, our living environment and living place also continuing development change. From the past caves bungalow development up to now tall buildings. Top super-tall in our life are cropping up everywhere, and are common. The emergence of glass curtain wall structure is building technology high speed development of product, beautiful atmosphere appearance, reasonable the stress of the introduction, connect fully efficient lighting let city more full-bodied breath. So it is the builder and user's push holding and the favour. Especially point supported glass curtain wall structure of the appearance of the curtain wall structure of all aspects of performance and a great increase and development. After investigation, at the top of the destruction of the main high building is due to the wind load, and the wind load lead to damage the first stage curtain wall structure in the periphery of the structure is the system, also is the curtain wall glass panel and support system.In view of this, this article point a type glass curtain wall cable truss support system in the wind load on the dynamic response analysis. With the focus on the following aspects:1.Point supported glass curtain wall type cable truss support system and the basic component of the basic mechanical characteristics. Including active and passive cable cable of the basic concepts and mechanical characteristics; Stem cell and beam element deformation coordination and deformation not harmonious principle; And the structure of the stiffness matrix and the difficulty in the construction.2.Cable truss for dynamic response analysis to the structure before must understand the basic vibration characteristics. In the paper the structure of the software ansys finite element modal analysis and research, and calculates the structure of the natural vibration before20order vibration frequency. The most by changing the structure of prestressed lasso, and cable length, diameter, poles and diameter poles the size of the glass panel five parameters, the analysis and comparison of structure parameters of the vibration frequency of influence and the change rule. 3.Research in wind load structure of wind vibration response of wind load is simulated and analyzed. In this paper the most widely used in the world of davenport spectrum is simulated for wind speed. Through the wind speed get wind pressure finally get wind load, and map out the wind load curve of the schedule.4.Paper last part of the application of finite element software ansys structure model and simulation on good wind load on the structure of the wind vibration response analysis, obtained respectively in corner, edge point model and intermediate point when the displacement process and wind speed schedule. Meanwhile, changes in the model of the structure of the lasso prestress, and cable length and diameter, poles glass panel size calculation statistics a glass panel that the maximum stress model, the maximum stress lasso and structure to the maximal displacement of a (deflection) change rule. Finally, the data normalization analysis, statistics finishing change parameters on the surface of glass panel maximum stress, the maximum stress lasso and structure to the maximal displacement of a (deflection) change the size of the effect.
