因此，本文對耗能梁段進行進一步計算分析，概述耗能梁段對整體性能的影響，並利用有限元程序ansys對耗能梁段進行數值計算：針對耗能梁段的屈服類型建立5種不同長度的模型，計算討論耗能梁段屈服類型的長度劃分；針對耗能梁段腹板高厚比、翼緣寬厚比以及梁段截面形狀等因素共建立了18種模型進行計算分析；針對加勁肋對耗能梁段的作用建立了4種模型，並結合已有的試驗闡述了加勁肋對耗能梁段的影響。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。This paper applies nonlinear finite element program bsnfem to analyze the behaviors of eccentrically braced steel frames under cyclic load. the study that comprehensive and systematic analyze the factor of links length, thickness of links flange, distance of links rib, thickness of links rib and angle of brace to be changed affect energy - dissipation capacity of d shape and k shape eccentrically braced steel frames have been some studied before. this paper fills the black in the filed factor of high - span ratio, brace stiffness and brace - to - beam connections to be changed affect energy - dissipation capacity of d shape and k shape eccentrically braced steel trames and any factor to be changed affect energy - dissipation capacity of y shape eccentrically braced steel frames
對耗能梁段的長度、耗能梁段腹板的厚度、耗能梁段翼緣的厚度、耗能梁段加勁肋的間距、耗能梁段加勁肋的厚度、支撐的夾角等因素的改變對d形、 k形偏心支撐鋼框架耗能的影響，前人已有一些研究，本文對這些因素的影響進行了全面系統的分析，完善了理論分析的不足；而結構高跨比、支撐剛度、支撐與梁的連接形式等因素對d形、 k形偏心支撐鋼框架破壞機理的研究以及各種因素對y形偏心支撐鋼框架破壞機理的影響，則很少有人涉及，本文對此也進行了深入系統的分析，填補了這一研究空白。To raise the critical stress of the web, we always lay some transverse stiffeners on the web, and also lay some longitudinal stiffeners sometime
為了提高腹板的臨界應力，通常都設有腹板橫向加勁肋，有時還在梁中段加設縱向加勁肋。At present, there are no information or specification on studying the transverse stiffener of the thinned - web beam systemically. and there are a small few literatures related on load - bearing ability and laying of the transverse stiffeners of the thinned - web beam

本文對受多個集中荷載作用的薄腹板梁的橫向加勁肋進行了研究，分析了利用腹板屈曲后強度時，橫向加勁肋的受力狀態、破壞機理，以及加勁肋局部承壓的強度計算公式和穩定計算方法。Results of the experiment shows that end - plate connections have excellent hysteretic behaviors, and the determination factors, which have crucial influence on the behavior, are end - plate thickness, column web thickness, and the rib stiffeners
試驗結果表明端板連接具有良好的滯回性能，端板厚度、節點域柱腹板厚度以及加勁肋構造是影響連接性能的主要因素。2 based on experimental results and finite elements analysis of new joint, the stress transfer mechanism of the new joint is analyzed. there are two stress transfer patterns about the new joint, one is for rectangular steel tubular column joint, its stress transfer pattern is that beam moment is transferred to column webs mainly by stiffeners, the other is for crft column joint, its stress transfer pattern is that part of beam moment is transferred from stiffeners to column webs, another part of beam moment is transferred to infilled concrete by column flange
（二）基於新型節點的試驗結果和有限元分析，研究了新型節點的傳力機理，其應力的傳遞路徑分為兩種：對于鋼管柱節點，梁端彎矩主要通過加勁肋板直接傳至柱腹板，對于鋼管混凝土柱節點，梁端彎矩一部分通過加勁肋傳給柱腹板，另一部分通過柱翼緣傳給鋼管內的混凝土。After comparing between the finite - element analysis and experimental results, the author verified the fem. then according to the chinese code, the nonlinear finite model of the beam - to - column is established which are made of different size components. the responses of beam - to - column web moment connections which are made of different size components are compared and analyzed from three facets, and the conclusions about the joints behavior are drawn : thicken the connection plate, lengthen the connection plate or use a back - up stiffer can improve the connection behavior, consist of improving the behavior of load - supported and reducing the stress convergence in the flange moment plates
本文根據我國規范的有關規定，自行建立了12個不同構件尺寸的樑柱腹板連接的三維有限元模型，對不同構件尺寸的樑柱腹板剛性連接節點在單向荷載作用下的反應進行了研究，從結構的mises應力等值線示意圖、梁端加載處的荷載? ?位移曲線、翼緣連接板兩端的mises等效應力以及翼緣連接板與柱相連接的三邊的mises應力等值線示意圖四方面進行了比較與分析，從而得出了不同構件尺寸的樑柱腹板剛性連接的在受力行為上的結論：增加翼緣連接板的厚度、增加翼緣連接板的長度以及採用柱的橫向加勁肋均可以改善節點的受力性能：提高節點的承載能力；減小翼緣連接板內部與柱翼緣邊的的應力不均勻現象，從而避免試件過早地發生破壞。By simulating body node with fea software ansys and comparing its results with the experiment ones, natural capacity of semi - rigid connection node itself was discussed, and the experimental results were analyzed additionally, and the bearing conditions of sections which could n ' t be tested in experiment were obtained, as well as two kinds of bearing conditions under different conditions that the connections with and without stiffener were compared in detail
在討論半剛性連接節點本身的性能時，通過有限元軟體ansys對節點進行三維非線性有限元精細模擬，將計算結果與試驗所得數據對比，對試驗結果進行補充分析，了解沒有測到試驗數據的節點組件在加載過程中的受力情況，並對帶雙腹板角鋼頂、底角鋼連接在有無加勁肋兩種情況下的受力狀態進行詳細對比。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
