本文提出了一种确定节点和杆件具有二面角对称性的棱柱形张拉整体结构自平衡位形的简单有效的方法。结果表明，该类结构的稳定性不仅与杆件的连通性直接相关，而且与杆件的几何形状（高径比）、自应力水平和杆件刚度有关。在稳定性研究的基础上，提出了一个杆数相对较少的结构的目录。
This paper presents a simple and efficient method to determine the self-equilibrated configurations of prismatic tensegrity structures, nodes and members of which have dihedral symmetry. It is demonstrated that stability of this class of structures is not only directly related to the connectivity of members, but is also sensitive to their geometry (height/radius ratio), and is also dependent on the level of self-stress and stiffness of members. A catalogue of the structures with relatively small number of members is presented based on the stability investigations.
