Abstract:

Based on ACCTS, the features of ACCTS were firstly described in detail. Secondly, three arrangement schemes of struts grid-jumping were proposed, which were compared with the original scheme in terms of pre-stress distribution, load condition, buckling resistance, steel consumption and so on, and the optimal grid-jumping order was determined. Finally, based on the optimal scheme and original scheme, the static and dynamic performances of two schemes were systematically comparatively studied. The research results show that under the condition that the static and dynamic performances of the original structure are unchanged, the optimal scheme after grid-jumping not only saves the amount of steel and improves the anti-buckling ability of the structure, but also simplifies structure system and reduces the construction difficulty by means of grid-jumping optimization. This research can promote the application of ACCTS in practical engineering.

Key words: civil engineering, annular crossed cable-truss structure, grid-jumping, load analysis, steel consumption, static and dynamic performance
