Elastic theory and plastic theory are adopted in the analysis of the two section composite beam. elastic theory suggests, on the condition of the same steel beam section size, the composite beam for the floorslab is suited lower flanges convertion section stiffness cuts down by 75. 1 %, elastic limit bending resistant capability cuts down by 47. 9 %, than the composite beam for the floorslab is suited on the top flange. it s conversion section stiffness is lifted 8. 0 %, elastic limit bending resistant capability is lifted 0. 20 %, than the steel beam
彈性理論分析的結果表明,在鋼梁截面大小相同的條件下,樓板位於鋼梁下翼緣的組合梁和樓板位於鋼樑上翼緣的組合梁相比,其換算截面剛度降低75 . 1 ,梁的彈性極限抗彎承載力降低47 . 9 ,樓板位於鋼梁下翼緣的組合梁和純鋼梁相比,其換算截面剛度提高8 . 0 ,梁的彈性極限抗彎承載力提高0 . 2 。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。Plastic theory suggests, the composite beam for the floorslab is suited lower flange, it s plastic limit moment cuts down by 52. 4 % than the composite beam for the floorslab is suited on the top flange. it s plastic limit moment lifts 8. 8 % than the steel beam, which is on the same condition
塑性理論分析的結果表明,樓板位於鋼梁下翼緣形式的組合梁和樓板位於鋼樑上翼緣形式的組合梁截面相比較,其塑性極限彎矩降低52 . 4 ,和同等條件下純鋼梁截面相比較,樓板位於鋼梁下翼緣的組合梁塑性極限彎矩提高8 . 8 。In elementary beam bending theory, it is assumed that the stresses are constant through the width of the beam. however, for the wide flange girders, the stresses are not uniform
