  1. In this thesis, four types of steel beam - rectangular cfst column connections, including normal welded flange plate ( wfp ) connection, bolted flange plate ( bfp ) connection, stiffened end plate ( sep ) connection and double split - tee plate ( dst ) connection, were designed based on the configuration of steel frame connection. total 8 models, 2 models of each kind of connections were tested under low - reversed cyclic loading at the end of cfst columns. the relationships between force and displacement at the end of columns, the relationships between the moment and rotation of the joints, degradations of strength and stiffness, ductility, failure mechanism and failure characteristics of these four connections under different axial - compression ratios were presented

    本文借鑒鋼框架節點構造,設計了四種類型矩形鋼管混凝土柱與鋼梁連接節點,包括常規栓焊( wfp )節點、翼緣全螺栓連接( bfp )節點、雙t板連接( dst )節點以及加勁端板連接( sep )節點,進行了四類節點8個模型試件在柱端低反復荷載作用下的抗震性能試驗研究,比較了不同軸壓比下節點的滯回性能、強度與剛度退化、延性、破壞機理與破壞特徵,主要結論有: 1 、節點的位移滯回曲與轉角滯回曲為塊型分佈,沒有或略有捏攏現象,耗能能力強; 2 、軸壓比對節點滯回曲有顯著影響,全部節點都有顯著的剛度退化; 3 、位移與轉角骨架曲在峰值荷載後有較平或下降段,具有良好的延性性能; 4 、從整體抗震性能上看,翼緣全螺栓連接節點、雙t板連接與加勁端板連接節點都優于常規栓焊節點,可在實際工程中加以推廣。
