Abstract
A new-type pre-stressed spatial structure, named Annular Crossed Cable-truss Structure, is proposed to overcome the shortages of the in-used Annular Open-web Cable-truss Structure for lack of disproportionate collapse resistance. The formulas of node coordinates of the Annular Crossed Cable-truss Structure in the pre-stressed state are derived in Cylindrical Coordinate System. It is found that the node coordinates are determined by five geometric parameters, the number of nodes in outside ring , the number of ring segments spanned over by cable-truss in plane , the distance between central point O and node in outside ring , the rise height and the sag height . The proposal of Annular Crossed Cable-truss Structure provides a new disproportionate collapse resistance design method for pre-stressed spatial structures and the derivation of the geometry parameters lays a foundation for further study on performance of the Annular Crossed Cable-truss Structure.
