［摘要］某超高層采用框架-核心筒結(jié)構(gòu)體系，在內(nèi)筒與核心筒之間采用伸臂桁架連接。介紹了這種結(jié)構(gòu)形式的特點，利用有限元軟件LS-DYNA分析了在控制工況作用下伸臂桁架與混凝土核心筒連接節(jié)點的工作性能，考察了伸臂桁架對混凝土墻體的影響及節(jié)點的破壞形態(tài)。結(jié)果顯示，在荷載標準組合作用下，混凝土剪力墻及節(jié)點滿足設(shè)計要求；在最不利工況作用下，混凝土剪力墻滿足承載力極限狀態(tài)要求；采用鑄鋼節(jié)點后滿足強節(jié)點的設(shè)計要求。

Abstract:The structural system，which the inner core connect huge column by outrigger truss，has been developed in recent years. The performance of the connection joint of outrigger and inner core or column is very important. Once the joint is failed, disastrous accident will be brought. At the beginning, the features of the joint were introduced, and then the working performance of the joint was analyzed using finite element software LS-DYNA based on a super high-rise building. Finally, some advices were given according to these results. According to these results, the joint satisfy design requirement under the nominal load combination. Under the least favorable load combination and using the connection of structural steel casting, the joint satisfy design requirement.
Keywords:connection joint; super high-rise building; outrigger; nonlinear; finite element analysis
