摘　　要：为了得到钢框架组合节点抗弯承载力的计算方法,采用"组件法",借鉴已有对各组件承载力的研究结果,计算抗弯承载力时考虑了包括钢梁柱屈曲、混凝土局部受压、腹板抗剪、栓钉剪切等因素对节点承载力的影响。根据足尺试验中组合截面应变分布特征,用两种方法推导出栓焊连接组合节点正负弯矩承载力公式。与现有试验数据的比较说明,公式可以较准确且偏保守地计算节点抗弯承载力,方便于设计应用。Based on the component method, the past studies on various components and the strain distribution in full-scale tests, the formula for calculating the fiexural strength of the composite bolt-welded connection under sagging and hogging moment is obtained. The calculation method also takes into account of the buckling of the steel member, local compression of the concrete, shear resistance of the beam web and shear-bearing capacity of the stud. Comparing with the experiment results, the method can calculate the flexural strength of the connection relatively accurately and conservatively, and can be easily applied in design work.
