Abstract
Tensegrity (TG) grids of bar-to-bar connection are studied in a general way in this paper. Their configurations can be classified into two types: one of TG prisms (anti-prisms), the other of TG truncated-pyramids (anti-truncated-pyramids). The present study shows distinct advantages for the latter type, and its structural properties are studied intensively. The results show that TG grids of bar-to-bar connection are not suitable for conventional usage and integral cable-tension is not applicable. New types of cable-strut systems may be more appropriate. The paper also points out that a low proportion of the number of struts to that of cables is not necessarily advantageous for structural efficiency. Moreover, the drawbacks of the present Newton iteration method are analyzed.
