摘　　要：索穹顶结构中压杆起着十分重要的作用,压杆的失稳将导致整体结构的失效。故本文研究了索穹顶结构在静力荷载作用下,基于压杆失稳的失效机理,提出了具体的失效判别依据,求得了相应的极限荷载。The struts of cable domes are the indispensable parts of structures and act as extremely imponant function. Buckling of Struts would lead to invalidation of whole structure. So the failure mechanisms of cable domes based on buckling of struts, subjected to static loads, are studied in this paper. The criteria for discrimination of structure failure are proposed for practical application, and the corresponding ultimate loads are obtained.

关 键 词：索穹顶 静力荷载 失效分析 压杆稳定
