Abstract  The cable-strut structural system is statically and kinematically indeterminate. The initial pre-stress is a key factor for determining the shape and load carrying capacity. A new numerical algorithm is presented herein for the initial pre-stress finding procedure of complete cable-strut assembly. This method is based on the linear adjustment theory and does not take into account the material behavior. By using this method, the initial pre-stress of the multi self-stress modes can be found easily and the calculation process is simplified and efficient also. Finally, the initial pre-stress and structural performances of a particular Levy cable dome are analyzed comprehensively. The algorithm has proven to be efficient and correct, and the numerical results are valuable for practical design of Levy cable dome.
