［摘要］基于巨型框架核心筒結(jié)構(gòu)體系中加強層伸臂桁架與巨型框架柱連接節(jié)點受力的特殊性，提出一種伸臂桁架復(fù)式鋼管高強混凝土柱的連接節(jié)點形式，運用ABAQUS軟件并結(jié)合深圳某超高層結(jié)構(gòu)設(shè)計，對該節(jié)點展開詳細(xì)的數(shù)值模擬分析。研究揭示了該節(jié)點的受力機理，并證明其在傳力上的可靠性，可為該類節(jié)點在超高層結(jié)構(gòu)中的應(yīng)用提供參考。

Abstract:A new kind of connection between outrigger truss and double steel tubular confined with high performance concrete column was put forward according to the particularity of the connection performance between strengthened story with outrigger truss and mega frame column in mega framecore wall structure system. ABAQUS was used to simulate the behavior of this kind of connection combined with a tall building in Shenzhen. The research reveals the working mechanism and the reliability of load transmission of those joints. The design reference for the application of this kind of connection in tall building was provided.
Keywords:outrigger truss； double steel tubular confined with high performance concrete column； connection joint； finite element analysis
