摘要
针对新型外套管式梁柱连接节点的力学性能,在国内外研究成果和试验数据的基础上进行了深入研究。提出采用极限状态控制法的三参数弯矩转角曲线方程,计算结果与试验结果吻合较好。依据此方程,在已知连接节点几何参数和材料性能的情况下可计算得到节点的弯矩转角曲线,为工程设计实践提供依据。
Based on previous research results and experimental data, the mechanical performance of outer-shell connection （OSC） is studied. The three-parameter model describing M -θ relationship is put forward and the calculation results of the model agree well with test data. With the model, the M -θ curve of OSC can be obtained by the parameters of material character and geometry size, and it can be referred for the engineering practice.
