[摘要]  考察在两种最不利工况下，伸臂桁架与外框柱节点设计安全性；节点传力是否合理；是否满足强节点弱构件的设计理念。有限元分析结果表明：伸臂桁架与外框柱节点设计满足承载力和刚度要求，达到了规范的强节点弱构件设计目标要求。同时作者在现有分析结果的基础上对原节点设计提出了优化建议。

Abstract: Under two most adverse conditions, the author examine outriggers and frame column’s joint design is safety or not; if joint power transmission is reasonable; if it meets the strong joint-weak component. Finite element analysis results show that: outrigger and frame column’s joint designing meets the capacity and stiffness requirements, meets strong joint-weak component. Also, the author gives optimization design of original design basis on the existing’s finite element analysis results.

Keywords: outrigger；joint design；finite element analysis；strong joint-weak component；optimization
