Composite cable and steel/aluminum structure is a new system. It is in a selfstress and stable self-equilibrated state, comprising a continuous set of tension members
(cables) and a discontinuous set of compression components (steel pipes or alloy tubes). Starting from an initial specified geometry and topology, the initial self-stress is determined using a dynamic relaxation method. The behavior of the structure is analyzed for safely resisting the self-weight and applied static load using the Newton-Raphson method. To understand its mechanical property, steel pipes and alloy tubes are used as compression members respectively in the two kinds of composite structures. Application of the process is shown with a numerical example. It is concluded that that improvement in engineering application of the composite cable and steel/aluminum structure has been achieved.
