| Summary |
In the design of large span structures. there exists the dilemma that. as the span of the structure is increased，many structural members end up carrying their own self-weight. Therefore. one of objects in the structural design of large span structures is to save on self-weight. In the paper, a structural system named “Truss Structures Stabilized by Cable Tension" is developed in order to reduce its own weight by reducing the number of compression members. An unstable truss structure composed of four truss members connected by pin-joints is stabilized by the self-equi1ibrated system which is introduced by using a post and eight cables. This stabilized truss structure is named "Unit Structure". This unit structure has no inextensinal displacement. but a self-equilibrated stress system. Then the unit structure belongs to the statically indeterminate and kinematically determinate frame. The truss structures stabil1ized by cable tension is an assemblage of the unit structure. As the unit structure is itself a statically closed and stabilized， it can be employed to assemble structure with various shapes. The structural behaviors of both the unit structure and the barrel vault shape truss structures stabilized by cable tension are investigated analytically and the guide lines in the practical design are provided， then the construction of barrel vault model roof is described.
