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
