[摘要] 以ANSYS有限元分析軟件為工具，建立了直接焊接式節(jié)點(diǎn)、外加強(qiáng)環(huán)板式節(jié)點(diǎn)、貫穿鋼筋式節(jié)點(diǎn)模型，并在此三種基本模型的基礎(chǔ)上改變節(jié)點(diǎn)相關(guān)參數(shù)，縱向分析得出每種節(jié)點(diǎn)在參數(shù)的變化與節(jié)點(diǎn)承載力變化的對(duì)應(yīng)關(guān)系，橫向分析得出此三種節(jié)點(diǎn)模型的承載力及延性的對(duì)比結(jié)果。從計(jì)算的結(jié)果的M-θ曲線中可看出貫穿鋼筋式節(jié)點(diǎn)延性及承載力均優(yōu)于直接焊接式節(jié)點(diǎn)和外加強(qiáng)環(huán)式節(jié)點(diǎn)。

Abstract: Using ANSYS finite element analysis software, there models, the directly welded joints, joints with exterior strength ring and joints impenetrated by reinforcements are built to analysis the characteristics of the rigid joint. With changing the parameters of the basic joints models and comparing longitudinally, the article concluded the corresponding relation between every parameter and capacity with comparing horizontally, the article concluded the capacity and ductility's relation of the three kinds of joints. Form the M-θ diagram, the capacity and ductility of joints impenetrated by reinforcements have the advantage over the directly welded joints, joints with exterior strength ring.
Keywords: concrete-filled steel column and steel beam ngidjoint; capacity ductility
