[提要] 利用非線性有限元法對不等寬K型方管間隙節(jié)點進行了數(shù)值計算,揭示了此類節(jié)點在弦桿軸力作用
下的極限承載力、變形、剛度等隨各幾何參數(shù)的變化規(guī)律,得出了軸向拉力和壓力及相關(guān)幾何參數(shù)對節(jié)點承載性能的影響的相關(guān)結(jié)論,可供工程設(shè)計參考。
[關(guān)鍵詞] 不等寬K型方管節(jié)點 節(jié)點性能 非線性有限元法 參數(shù)分析Nonlinear finite element analyses on stepped K-type gapped RHS-joints subjected to chord axial loading are carried out. The influences of geometrical parameters on the load-carrying capacity,deformation and stiffness of the joints are presented.The results are recommended for design.
Keywords: stepped K-type RH-joints; static behavior; nonlinear finite element; parameter analysis
