    • Abstract
  • Hoop cable is generally continuous in suspend-domes. To assess the influence of friction during the construction procedure of tensioning continuous hoop cable of suspend-dome, the paper utilized an example of four nodes and four elements. The change and distribution of element force during tension were examined. The method of calculating friction during tensioning continuous hoop cable was presented according to the fact that the non-stress length of the continuous hoop cable is fixed after slippage. Then, the paper analyzed the construction of sunflower 1 type and rib 1 type suspend-domes considering the change of friction coefficient, tension element and tension force. The results displays an asymmetric distribution of cable-strut force, and strut slant would occur in suspend-dome after construction by tensioning continuous hoop cable because of friction. So it is unfavorable that tensioning continuous hoop cable by fewer tension elements in the practical project.
