“…However, according to the literature, the primary research objects of structural robustness have included frame structures [19], frame core tubes [20], bridges [21], and underground structures [22]. Although research has gradually expanded to include large-span structures, researchers have primarily focused on rigid spatial structures, such as trusses [23], grid frames [24], and latticed shells [25], and on rigid pretension structures, such as tension string structures [26] and chord-supported grid structures [27]. Nonetheless, a flexible cable dome differs from a rigid structure.…”
