【摘要】：鋼板剪力墻與防屈曲鋼板剪力墻作為新型的抗側(cè)力構(gòu)件具有承載力高、延性好、耗能能力強等優(yōu)點,因此在實際工程中具有良好的應(yīng)用前景。鋼板剪力墻可以充分利用其屈曲后強度,形成“拉力帶”使鋼板剪力墻繼續(xù)承載,能夠保持良好的延性和較高的承載力。防屈曲鋼板剪力墻通過鋼板兩側(cè)設(shè)置混凝土板,能有效防止鋼板的平面外失穩(wěn),使鋼板近似平面內(nèi)受力工作,其耗能能力進一步提高。但在鋼板剪力墻和防屈曲鋼板剪力墻的施工和使用階段,由于不可避免的承受一部分豎向荷載作用,豎向荷載會影響剪力墻的抗剪承載力和耗能能力,但目前相關(guān)研究很少且缺乏相應(yīng)的設(shè)計方法,因此本文主要針對考慮豎向荷載作用的鋼板剪力墻和防屈曲鋼板剪力墻的滯回性能進行研究。論文中具體完成以下內(nèi)容:(1)采用ABAQUS有限元軟件建立精細(xì)化有限元模型,特別在防屈曲鋼板剪力墻的模型中采用實體元模擬了鋼筋混凝土板,能更精確模擬防屈曲鋼板剪力墻在滯回荷載作用下的受力性能,并用已有試驗結(jié)果驗證了鋼板剪力墻和防屈曲鋼板剪力墻有限元模型的正確性。(2)對考慮豎向荷載影響的鋼板剪力墻滯回性能進行系統(tǒng)的有限元分析。通過對典型模型的分析揭示出豎向荷載影響下鋼板剪力墻在往復(fù)荷載作用下的受力機理。在此基礎(chǔ)上,進一步分析了框架柱抗彎剛度、鋼板高厚比、跨高比等參數(shù)對鋼板剪力墻滯回性能的影響;研究結(jié)果表明:豎向荷載降低了鋼板剪力墻的承載力、剛度及耗能能力;基于大量參數(shù)分析結(jié)果,提出了考慮豎向荷載影響的鋼板剪力墻抗剪承載力計算方法。(3)對考慮豎向荷載影響的防屈曲鋼板剪力墻滯回性能進行了有限元分析。研究了典型防屈曲鋼板剪力墻考慮豎向荷載作用時的受力機理。在此基礎(chǔ)上,分別研究了鋼板高厚比、跨高比對防屈曲鋼板剪力墻滯回性能的影響。研究表明:豎向荷載會降低防屈曲鋼板剪力墻的抗剪承載力和耗能能力。基于大量參數(shù)分析結(jié)果,提出了考慮豎向荷載作用的防屈曲鋼板剪力墻抗剪承載力計算方法。
[Abstract]:Steel plate shear wall and anti-buckling steel plate shear wall, as new type of lateral force resistant members, have the advantages of high bearing capacity, good ductility and strong energy dissipation capacity, so they have a good application prospect in practical engineering. The steel plate shear wall can make full use of its post-buckling strength, form a "tension belt" to make the steel plate shear wall continue to bear, and can maintain good ductility and high bearing capacity. The anti-buckling steel plate shear wall can effectively prevent the out-of-plane instability of the steel plate by setting concrete slabs on both sides of the steel plate, make the steel plate work approximately in-plane force, and further improve its energy consumption capacity. However, in the construction and use stage of steel plate shear wall and anti-buckling steel plate shear wall, because of the inevitable bearing part of vertical load, vertical load will affect the shear capacity and energy dissipation capacity of shear wall, but at present, there is little related research and lack of corresponding design methods. Therefore, this paper mainly studies the hysteretic behavior of steel plate shear wall and anti-buckling steel plate shear wall considering vertical load. The main contents of this paper are as follows: (1) the fine finite element model is established by using ABAQUS finite element software, especially in the model of anti-buckling steel plate shear wall, the reinforced concrete slab is simulated by solid element, which can more accurately simulate the mechanical behavior of anti-buckling steel plate shear wall under hysteretic load. The correctness of the finite element model of steel plate shear wall and anti-buckling steel plate shear wall is verified by the existing test results. (2) the hysteretic behavior of steel plate shear wall considering vertical load is analyzed systematically by finite element method. Through the analysis of the typical model, the stress mechanism of steel plate shear wall under the influence of vertical load is revealed. On this basis, the effects of bending stiffness, steel plate height to thickness ratio and span height ratio on the hysteretic behavior of steel plate shear wall are further analyzed, the results show that the vertical load reduces the bearing capacity, stiffness and energy consumption capacity of steel plate shear wall. Based on a large number of parameter analysis results, a calculation method of shear capacity of steel plate shear wall considering vertical load is proposed. (3) the hysteretic behavior of steel plate shear wall considering vertical load is analyzed by finite element method. The stress mechanism of typical anti-buckling steel plate shear wall considering vertical load is studied. On this basis, the effects of steel plate height to thickness ratio and span to height ratio on hysteretic behavior of anti-buckling steel plate shear wall are studied respectively. The results show that the vertical load can reduce the shear capacity and energy dissipation capacity of the steel plate shear wall. Based on the results of a large number of parameter analysis, a calculation method of shear capacity of steel plate shear wall considering vertical load is proposed.
