摘　　要：非承重玻璃肋点支承全玻璃幕墙承重索的截面选择、初始预应力取值及玻璃肋稳定分析等设计核心内容缺少相应的研究理论基础和设计依据。通过对非承重玻璃肋点支承全玻璃幕墙系统进行分析,提出了承重索的截面计算和预应力取值理论和玻璃肋稳定分析方法思路,得出了水平风荷载对承重索影响极小、可忽略不计以及温度作用对承重索的影响较大、截面不宜随意加大的结论。Some core design aspects of non-load bearing glass rib point supported fhll glass curtain wall, such as cross-section selection, value of initial prestress and stability analysis of glass rib, etc., lack of relevant theoretical foundation and design basis. After analysis on the non-load bearing glass rib point supported full glass curtain wall system, the cross-section calculation and prestress value theories for load bearing cable and analysis method for glass rib stability were proposed. It was concluded that horizontal wind load makes vary little influence on the load bearing cable and could be ignored, but temperature which produces obvious influence of the load bearing cable must be considered, cross section should better not be enlarged without careful analysis.
