摘　　要：点支式玻璃幕墙单层索网体系中,玻璃通过连接件和索网结构相连,参与支承结构的受力,本文利用ANSYS有限元软件建立玻璃和索网共同工作的模型,研究玻璃刚度及节点约束对单层索网承载性能的影响,并结合相关试验和计算结果对有限元计算模型进行验证.结果表明:考虑玻璃作用降低了索网幕墙的位移和索力,对索网承载性能有利;节点约束能力越强,玻璃的贡献越大.Abstract： In the monolayer cable net for point supported glass curtain wall, glass is connected with cable net by connectors and bears loads together with supporting structure. The corporate working models of glass and cable net are established and analyzed by the finite element analysis software ANSYS. The influence of glass stiffness and joint constraint on the loading capacity of cable net is analyzed. The results of the finite element models are compared with the correlative experiments and calculation results by other researchers. It is demon- strated that the glass can decrease the deflection and cable force, so it contributes to the loading capacity of the cable net. The stronger the joint constraint ability is, the greater the contribution of the glass is.
