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。Thecalculating results show that the composite action between concrete floor and steel beamsgreatly influence the bending bearing capacity and initial rotational stiffness of joints, it shouldbe considered in practical engineer. reinforcement ratio of lengthways reinforcing bar andthe stiffener of web have great influencer on the behavior of connections, while the thicknessof end - plate and degree of shear connection have a litter influence on its behavior
分析計算結果表明:樓板與鋼梁的組合作用對節點的抗彎承載力及初始轉動剛度的影響非常大,實際工程中節點設計應當考慮這種組合作用;樓板內縱向鋼筋配筋率與柱腹板加勁肋對節點性能影響顯著,而連接端板厚度及剪力連接程度的影響則不是太顯著。The factors, such as end - plate thickness, bolt ' s types, beam and column " flank, that can effect on the joint rigidity and moment capability, are analyzed
分析了節點端板厚度、螺栓類型、端板的加勁肋等因素對節點剛度以及抗彎承載力的影響。What banker applies at most is tall open quotation, amount of gather contest price is very large, but share price rushs on the powerful momentum for afterwards eve hard, turn around downward, to the limit of one ' s capacity drops broken all valence, although dish in your writing accepts the order, but share price goes cast apparent be enslaved to be enslaved to all of valence press instead, point of price of before one day of closing quotation also does not have a bit resistance, all the speed of price be issued to lower levels and share price keep basically consistent, because be banker concentration, shipment causes
莊家運用得最多的是高開盤,集合競價量很大,但股價難以為繼前日的強勁勢頭上沖,掉頭向下,放量跌破均價,雖然盤中有大筆接單,但股價走拋明顯受制於均價的反壓,前一日收盤價處也沒有絲毫反抗力,均價下行的速度與股價基本保持一致,因為是莊家集中出貨造成的。The research results indicate that it is the best plan for suspension rod to be constructed from main tower to side pier and for second dead load to be loaded before the bridge has been completed
4 .研究了主纜矢跨比、加勁梁剛度、主塔剛度、主纜抗拉剛度等結構參數變化對平勝大橋靜力力學性能的影響。Experimental results show that the new cfrt - column to steel - beam joints proposed in this paper possess good earthquake resistant capacity. the infilled concrete benefit to restrain the buckling deformation of column webs, increase the strength and stiffness of the joint. the lengthened stiffener can transfer much more beam moment, make the strength of the joint increased
試驗表明,在保證焊接質量的前提下,本文提出的新型方鋼管混凝土柱?鋼梁的節點具有良好的抗震性能;內填混凝土有利於抑制柱腹板的屈曲變形,增加節點的承載力和剛度;加勁肋長度的增加有利於傳遞梁端彎矩,使節點的承載力提高。Abstract : with the increasing of suspension bridge ? s span, the gravity stiffness of suspension cable itself is more important than vertical deflection resistance stiffness of stiffening girder which is serviced for the whole structure. in order to provide more knowledge of gravity stiffness of suspension cable, in this paper, gravity stiffness of suspension cable is formulated briefly and theoretically in case of ignoring the existing of the stiffening girder. the deformation and internal force of suspension cable can be calculated approximately in this way
文摘:隨著懸索橋跨度的增大,加勁梁的豎向抗彎剛度提供給整個橋跨結構的剛度僅佔次要地位,而懸索自身的重力剛度卻佔有重要的作用.為加深對重力剛度的進一步認識,筆者對特大跨度的懸索橋的重力剛度進行簡要的理論推導,在忽略加勁梁存在的情況下,可近似地計算懸索橋的變形和內力In addition, the analysis and test for the entire stability and limited carrying capacity are completed and results show that pingsheng bridge is also safe enough. 4. the influence on the static performance for pingsheng bridge of structural parameters, such as rise - span ratio of main cable, stiffened girder rigidity, main tower rigidity and main cable rigidity, is studied
