［摘要］通過試驗對1/4和1/2環(huán)形加肋鋼管插板連接節(jié)點基于鋼管控制的極限承載力進行了研究。在此基礎上，根據(jù)能量理論和虛功原理，提出了適用于估算此類節(jié)點極限承載力的分析模型，用數(shù)值分析方法得出了節(jié)點極限承載力，并與試驗結(jié)果、有限元和AIJ計算結(jié)果進行了比較，證明該理論分析模型的適用性較好。
［關鍵詞］環(huán)形加肋；鋼管節(jié)點；屈服線模型；極限承載力；虛功原理

Abstract:Experimental study was performed to investigate the behavior and strength of tubegusset joints with 1/4 and 1/2 annular ribbed plate.Based on energy theory and virtual work principle, analysis model for calculating the ultimate bearing capacity of tube-gusset joints was put forward, ultimate bearing capacity of tube-gusset joints was obtained through numerical method. Compared the strength of joint which obtained according to above model with the results of experiment, FEM and AIJ, it is proved that the calculation method model has the theoretical and practical significance for design.
Keywords:annular ribbed plate；steel tubular joint; yield line model; ultimate bearing capacity; virtual work principle
