[摘要]支付寶總部大樓中采用了鋼桁架-鋼管混凝土柱節(jié)點,此類節(jié)點是結(jié)構(gòu)傳遞荷載的關(guān)鍵部位,受力復(fù)雜,是設(shè)計重點。通過有限元分析和模型試驗,討論了節(jié)點的受力性能、薄弱部位與破壞模式。依照分析結(jié)果修正初始節(jié)點方案,確定節(jié)點最終構(gòu)造,使其具有良好的承載能力。

Abstract: Steel truss concrete filled steel tubular(CFT) column joint was adopted in the project of Alipay Headquarter. It plays an important role on load transfer in the structure, and it is in complex stress condition. Joint design is important to the project. Load performance of joint, weak position and failure mode were discussed by means of FEM analysis and model test. Original joint design was modified according to the analysis results. Final design was adopted to ensure the joints have good bearing capacity.
Keywords: Alipay Headquarter; steel truss CFT column joint; finite element analysis; model test
