[提要] 對實(shí)際工程中所采用的T型鋼半剛性連接節(jié)點(diǎn)性能進(jìn)行了研究，采用通用的有限元程序ANSYS對節(jié)
點(diǎn)性能進(jìn)行了非線性有限元分析，討論了節(jié)點(diǎn)各組成要素對節(jié)點(diǎn)性能的影響。結(jié)果表明：柱翼緣厚度、T
型鋼翼緣厚度和連接螺栓豎向間距對節(jié)點(diǎn)性能影響較大，而柱腹板、T型鋼腹板以及連接螺栓水平方向間距對節(jié)點(diǎn)性能影響較小，節(jié)點(diǎn)破壞主要由柱翼緣和T型鋼翼緣控制。研究表明，T型鋼梁柱連接節(jié)點(diǎn)屬于半剛性連接節(jié)點(diǎn)，節(jié)點(diǎn)的半剛性對鋼框架性能影響非常大，設(shè)計中不容忽視。

Research on the Behavior of T\|stub Semi\|rigid Connections of Steel Frames/Shu Xingping１，Hu Xibing１，Xiong Yao2(1 College of Civ. Engineering,Hunan University,Changsha 410082,China; 2 Hunan Urban Construction College,Xiangtan 411101,China)
Abstract:The research on the behaviors of Tstub semirigid connections applied in some factual projects is done.With the  finite element program ANSYS，the nonlinear analysis to this connection is made，and the effects of its components on its behaviors are discussed.The results show that the thickness of flange of the column and the Tstub and the vertical interval of bolts greatly influence the behaviors of the connections，while
the thickness of the web of the column and the Tstub and the horizontal interval of bolts have little influence on its behaviors.The research shows that this kind of Tstub connections is semirigid one，and the behaviors of semirigid connections will make great effects on the behaviors of steel frames，which can not be neglected to
design the steel frames.
