The Study On Mechanical Properties Of Glass Curtain Wall And Cable Truss Structure

Prestressed point fixed glass curtain wall with the cable truss, is a kind of flexible structure system. Due to its unique effect in architectural art, in recent decades it has been more and more used in the building. The current theory for the structure system is lack of depth. The curtain wall structure instance often destroys because of the wind loads. So the study in this area is of practical significance.This paper makes a detailed analysis of the mechanical principle of the glass panel and the cable truss supporting system, gets the basic equation of the cable truss nonlinear finite element, and analyses the influence factors of the cable truss rigidity. According to the collaborative analysis method between the cable truss and the glass, this paper makes an analysis on the point fixed glass curtain wall system with the cable truss, has a derivation of the main factor which affects the cooperative working performance between the double-layer cable net and the glass, and makes an analysis on the whole mechanical performance of the point fixed glass curtain wall with the cable truss with collaborative work. The paper also analyses the effect of the various parameters on the whole mechanical performance of the structure with the collaborative work and without the collaborative work.This paper analyses the characteristic of the wind load on the glass curtain wall, summarizes its change rule with the different height, and makes a derivation of the calculation method of the standard values of the wind loads. The paper uses ANSYS software to calculate the wind load at different height. The results was obtained, which was compared with the results of the uniform wind load. The detailed analysis of effect of the wind load on the structure’s displacement was made.
