| Abstract: | Spatial cable truss structures are composed of orthogonal prestressed cable trusses which combines prestress technology with space grid structures. The behavior of orthogonal spatial cable truss is analyzed in this paper. The mathematical model of an equivalent continum is proposed and solved by the energy variational principle. A numerical example is also given for reference in practical design. |
