摘　　要：单层平面索网点支式玻璃幕墙是一种墙体的围护结构,其结构体系是拉索桁架及拉杆桁架的简化形式。幕墙结构体系主要是在动力作用下破坏,所以文章运用有限单元法,考虑幕墙支承体系的几何非线性及玻璃面板的协同作用,来研究结构体系的自振特性。研究表明索网幕墙结构体系的频率密集,并受自身因素的影响。Single plane cable networks supported glass curtain wall is a kind of retaining structure. The structure is a simplified form of the guyed truss and bars of the truss structure. The glass curtain wall mainly destroy under the Dynamic Loads, so, the article use the finite element method,consider the geometric nonlinearity and the synergy of glass panel of the curtain wall support system, to study the vibration characteristics of the structural system. The results show that the frequency-intensive of the curtain wall structural system, and influence by its own factors.
