均布荷载下平面柔索幕墙受力性能的解析方法

Analytic Method of Mechanical Performance of Plane Cable Net Under Uniformly Distributed Load

平面柔索幕墙面外刚度主要由索中初始张力和索的伸长变形提供。在计算面外荷载作用下索网的受力性能时,必须考虑结构的几何非线性特性。采用解析法推导出均布荷载作用下平面索网的变形和索中拉力计算公式,为设计人员进行索网方案设计提供了方便。

The out-plane stiffness of the curtain wall supported by the tensioned plane cable net is mainly provided by the initial tension force and the elongation of the cable. The structure＇ s geometric nonlinear characteristic must be considered when investigating the mechanical performance of the plane cable net under loads. The formulas of the tension in cable and the deformation of the cable net tamer uniformly distributed load have been deduced by the analytic method. It may be convenient for engineers to design a plane cable net in conceptual phase.
