[提要]  通过对足尺模型试验数据和有限元模型计算数据的分析，利用应力集中系数的方法对使用节点板连接的K型钢管节点的局部应力进行了研究，并拟合了应力集中系数的计算公式。该公式可以直接应用于K型
钢管节点的局部应力设计。

Through the data analysis of full-size models and FEM models,research about the stress concentrations in K-joints of tube-gusset plate connections has been done with the method of stress concentration factor. And the regression equation that can be directly used in the process of design is educed.
Keywords: tube-gusset plate connections; K-joints; stress concentration factor
