摘要
通过有限元数值分析方法,从节点板尺寸、主管径厚比、主支管轴线夹角、主管轴力等方面开展了插板连接管节点极限承载力的参数研究,得到了管节点各个参数对其承载力的不同影响规律,并给出了工程设计的合理建议。
Based on methods of finite element numerical analysis, several finite element models about different parameters are calculated, including sizes of gusset plates, ratios of diameter and thickness for chords, angles for chords and bracing members and loads of chords, etc. Corresponding effect rules on ultimate strength of tube-gusset plate connections are concluded, and some practical advices are provided.
