［摘要］在试验研究的基础上，依据已通过合理性验证的有限元计算模型，对单角钢连接节点板进行了有限元参数分析，重点研究了几何参数、钢材强度变化、是否设置竖腹杆、竖腹杆荷载比例、受压腹杆肢宽变化以及偏心作用对单角钢连接节点板受压极限承载力的影响。在此基础上，通过考虑各参数对节点极限承载力的影响，提出了该类节点的极限承载力计算公式。

Abstract:A parametric study was conducted to investigate the ultimate strength of single angle-gusset plate connections. The effects of geometric parameters, yield strength of steel, proportion of load on vertical web member, dimensions of compressive diagonal web member and eccentricity on the ultimate strength were considered. Based on the analytical results, a formula for predicting the ultimate strength of single angle-gusset plate connections is proposed.

Keywords:gusset plate; compressive ultimate strength; finite element parametric study; design formula
