    Cyclic Behavior of Steel Beam to CFT Column Connections with Gusset Plates by Peng Wang, Zhan Wang, Jianrong Pan, Yanjun Zheng, Deming Liu

    Published 2019-01-01
    “…Experiment results indicated that the gusset plates in BBC (beam-brace-CFT) connections could effectively move the plastic hinge on beam away from the column face, reduce the strain concentration between the beam end and column face, and notably improve the hysteretic behavior; the plastic rotation was able to achieve at least 4% story drift angle before 20% strength degradation. Numerical studies were carried out and validated by experiment results, and then the influence of the weld length and strengthening methods were investigated; some improvement of design suggestions was proposed.…”
