  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周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 、節點的位移滯回曲線與轉角滯回曲線為塊型分佈，沒有或略有捏攏現象，耗能能力強； 2 、軸壓比對節點滯回曲線有顯著影響，全部節點都有顯著的剛度退化； 3 、位移與轉角骨架曲線在峰值荷載後有較長的水平或下降段，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。
  2. The formulas on crack width of rc beams and src beams are analyzed at home and abroad too. the calculation formulas on the maximum crack width of src beam under short time load are suggested. the calculation result tallies that of tests well

    分析比較了國內外鋼筋混凝土梁和勁性鋼筋混凝土梁裂縫計算公式，提出了勁性鋼筋混凝土梁在短期荷載作用下的最大裂縫寬度計算公式，其計算值與試驗值吻合較好。
  3. Based on experimental research and theoretical analysis, investigations on the new type of joint are made systematically, the main contents and results include the following items. 1 four specimens of new joints between cfrt columns and steel beams are designed. by low - cyclic reversed load test, skeleton curves of new joints and shearing deformation in joint core area are studied, the influence of parameters, such as concrete cores, length of stiffener, and relative dimensions of column and beam, is discussed

    本文在分析現有節點方案特點的基礎上，提出了角鋼加勁式節點方案，並採用試驗和理論分析相結合的方法，對這種新型節點進行了系統研究，主要研究內容與成果如下： （一）設計了4個新型方鋼管混凝土柱?鋼梁節點的試件，通過對新型節點的低周反復荷載試驗，研究了新型節點的骨架曲線和節點核心區剪切變形等，探討了內填混凝土、加勁肋長度和樑柱相對尺寸等對節點抗震性能影響。
