Research on Form Finding of Monolayer Spoke Cable Net Structure

索网结构的初始状态几何确定和零状态几何确定问题是索结构设计中得重中之重,其中单层轮辐式索网结构形状找形与传统索结构找形方法不同,详细阐述了单层轮辐式索网结构初始形态几何位形和零状态找形方法,并在参数化平台RHINO和Grasshopper结合四支座简化算例,证明文中阐述找形方法针对单层轮辐式索网结构具有良好的精确性和适用性。

The geometric determination of initial state and zero state of cable net structure is the most important problem in the design of cable structure.The shape finding method of monolayer spoke cable net structure is different from that of traditional cable structure.In this paper,the shape finding method of initial state and zero state of monolayer spoke cable net structure is described in detail,and the method is applied in the parametric platform of rhino and grasshopper.Finally,a numerical example is given to show that the proposed method has good accuracy and applicability for monolayer spoke cable net structure.
