［摘要］針對(duì)傳統(tǒng)鋼結(jié)構(gòu)梁柱鋼節(jié)點(diǎn)截面突變處較易出現(xiàn)應(yīng)力集中現(xiàn)象展開(kāi)，選取2個(gè)擴(kuò)翼型節(jié)點(diǎn)和1個(gè)傳統(tǒng)節(jié)點(diǎn)，通過(guò)ABAQUS有限元軟件，采用低周循環(huán)位移荷載模擬地震作用，分析了普通節(jié)點(diǎn)和擴(kuò)翼型節(jié)點(diǎn)的抗震性能。分析結(jié)果表明：擴(kuò)翼型節(jié)點(diǎn)的抗震性能比傳統(tǒng)節(jié)點(diǎn)較為優(yōu)越，隨著擴(kuò)翼尺寸的增大其抗震性能呈更好的趨勢(shì)；建議在強(qiáng)震地區(qū)的鋼框架結(jié)構(gòu)中優(yōu)先選用擴(kuò)翼型節(jié)點(diǎn)。

Abstract: The severe stress concentrating is obvious in sharp section change of traditional steel frame beam column connections. Two widened beam flange connections and one traditional connections were selected. Anti-seismic property of widened beam flange connections and traditional joints was analyzed by finite element software ABAQUS, at the same time, seismic excitation can be modeled by low cycle displacement loading. The analytical results show that the anti-seismic properties of widened beam flange connections are superior to traditional joints. Meanwhile, anti-seismic properties improve as its size grows. As a result, it is suggested that widened beam flange connections should be adopted preferentially in the region of strong earthquakes.
Keywords: widened beam flange connection; anti-seismic property; rigid coupling; low cycle displacement loading
