(同濟(jì)大學(xué)建筑設(shè)計(jì)研究院,上海 200092)[摘要]方管柱和H型鋼梁采用隔板貫通式連接而成的鋼框架成為多高層建筑的結(jié)構(gòu)體系的一種良好的選擇,在我國(guó)還沒有設(shè)計(jì)準(zhǔn)則可循。為了促進(jìn)方管柱H型鋼梁隔板貫通式節(jié)點(diǎn)的應(yīng)用,在試驗(yàn)數(shù)據(jù)的基礎(chǔ)上對(duì)其進(jìn)行了有限元數(shù)值分析,對(duì)比隔板貫通節(jié)點(diǎn)與柱貫通節(jié)點(diǎn)的異同點(diǎn),并分析了隔板挑出長(zhǎng)度和軸壓比對(duì)節(jié)點(diǎn)承載力的影響,提出改進(jìn)方向。[關(guān)鍵詞]隔板貫通式節(jié)點(diǎn);滯回性能;有限元分析;方管柱;H型鋼梁Seismic Performance of H-Beam to Square Tubular Column Connections with Through DiaphragmsZhuang Lei(Architectural Design & Research Institute of Tongji University,Shanghai 200092,China)Abstract:In multi-storied and high-rise buildings,there are several types to connect H-section steel beams to square tubular columns. The connection with through diaphragms is one of them,which has lower fabrication cost and convenient construction. To promote the application of H-section beam to square tubular column connection with through diaphragms,finite element numerical analysis is carried out on the basis of experimental datas. The similarities and differences are analysed between joint with through diaphragms and through columns. It also finds out the influence of diaphragm extend length and axial compression ratio on joint behavior and points out the direction of improvement.Keywords:joint with through diaphragms; hysteretic performance; analysis; square tubular columns; H-section beams參考文獻(xiàn)[1]蔡益燕. 阪神地震后日本鋼結(jié)構(gòu)的發(fā)展[J]. 中國(guó)建筑金屬結(jié)構(gòu),2005,(8).[2]日本建筑學(xué)會(huì). 鋼結(jié)構(gòu)接合部設(shè)計(jì)指針(Recommendation for design of connection in steel structures,原文為日文)[S],2001.[3]日本建筑中心. 冷成型方鋼管設(shè)計(jì)施工手冊(cè)(冷間成形角形鋼管設(shè)計(jì)施工マニユアル,原文為日文)[S],2003.[4]劉洋.冷彎方管柱與H型鋼梁連接性能的分析[D].武漢:武漢理工大學(xué).[5]石井匠,菊川春三,森田耕次,等. 通しダィアフレム形式柱梁接合部の破斷性狀に關(guān)する試驗(yàn)的研究[C]. 鋼構(gòu)造論文集,1999,6(24):87102.[6]李星榮,魏才昂,等. 鋼結(jié)構(gòu)連接節(jié)點(diǎn)設(shè)計(jì)手冊(cè)(第二版)[M]. 北京:中國(guó)建筑工業(yè)出版社,2005.
