[提要] 介紹了鋼結(jié)構(gòu)加腋型梁柱焊接節(jié)點(diǎn)的結(jié)構(gòu)、形狀、主要參數(shù)與重要部件，并對其抗震性能進(jìn)行了探
討。加腋型節(jié)點(diǎn)的塑性鉸在遠(yuǎn)離柱翼緣面的梁上形成。與一般的梁柱節(jié)點(diǎn)相比，其韌性行為穩(wěn)定，強(qiáng)度得到提高。與目前流行的削弱梁截面的改進(jìn)型節(jié)點(diǎn)比較，加腋型梁柱焊接節(jié)點(diǎn)具有更大的塑性轉(zhuǎn)角與更強(qiáng)的抗震性能。
[關(guān)鍵詞] 鋼結(jié)構(gòu) 加腋 梁柱節(jié)點(diǎn) 塑性鉸 抗震性能The configuration,shape,main parameters and important components of beam-column welded connection with welded haunch in steel moment-frame are presented,and its aseismic performance is discussed. Studies indicate that the connection with welded haunch shifts plastic hinge away from the face of the column. Compared with normal connection, this connection has a steady performance of the ductility,its strength is also improved, and achieves larger plastic rotation than that with RBS( Reduced Beam Section), therefore, has better aseismic performance.
