Abstract
The Annular Crossed Cable-Truss Structure (ACCTS) is a new type of tensile spatial structure with a configuration suitable to cover large-span stadiums. Its configuration has potential to perform well in disproportionate collapse resistance. However, static behavior of the ACCTS hasn稚 been investigated in depth. In this paper, parametric analysis was carried out. Geometric parameters and pretension of structural system were considered. With the results it is found that pretension, the number of connections on the outside ring beam and the sag height ratio influenced the structural stiffness the ACCTS obviously and can be used to adjust the structural stiffness during the structural design. It is also observed that the rise height ratio has little effect on the structural stiffness but can be used to adjust the curvature of the top layer to make the tensile membrane well tensioned.
