Research on cylindrical and spherical tensegrity modules are extensively carried out. However research on other tensegrity modules is little reported. This paper presents an exploratory study on a new kind of tensegrity module - "torus". The topology of the torus tensegrity is firstly introduced. Then the initial form-finding of the torus tensegrity is discussed. The static and dynamic analysis of the tor-us tensegrity shows that prestressing has a stiffening effect on infinitesimal mechanism modes if the geometry is properly arranged. A new cable dome with a torus tensegrity employed as its ring beam is finally proposed. The behavior of the new dome is also examined. The work here will provide a reference for further research and application of the torus tensegrity.
