［摘要］在試驗研究的基礎上，依據(jù)已通過合理性驗證的有限元計算模型，對單角鋼連接節(jié)點板進行了有限元參數(shù)分析，重點研究了幾何參數(shù)、鋼材強度變化、是否設置豎腹桿、豎腹桿荷載比例、受壓腹桿肢寬變化以及偏心作用對單角鋼連接節(jié)點板受壓極限承載力的影響。在此基礎上，通過考慮各參數(shù)對節(jié)點極限承載力的影響，提出了該類節(jié)點的極限承載力計算公式。

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
