ABSTRACT
The cable dome is a full-tension space structure with light form and high efficiency (Lu et al. 2005), where components are prestressed to provide the whole rigidity. The traditional Geiger and Levy cable domes have been successfully applied in many domestic and foreign large-span structures, such as the 1985 Seoul Olympic Games gymnastics and fencing arenas (Geiger et al. 1986) and the 1996
flexible cables, and the whole rigidity of the structure is not adequate and sensitive to the eccentric load; and (3) in the flexible hinge cable system, it is difficult to control component size precision and construction deviation and results in tension forming scheme increasingly difficult. Therefore, scholars worldwide have put forward the new cable dome structure scheme, which mainly includes the layout change of ridge cables (Yuan & Dong 2005, Bao 2007), key member replacement of the structure (Li 2007), or combination forms of the structure (Dong et al. 2010, Zhang & Liu 2010, Lu et al. 2015), thus improving the weakness of the traditional cable force characteristics or relatively lowering the difficulty of construction, which promoted the construction of cable dome structure.
