【摘要】:通過對以往鋼板剪力墻現(xiàn)有資料的研究,本文提出了一種通過將兩個折板組合形成的橫置蜂窩形截面鋼板剪力墻(THSS-SPSW),來改善薄鋼板剪力墻平面外的穩(wěn)定性較差的缺陷。本文采用有限元數(shù)值分析方法對橫置蜂窩形截面鋼板剪力墻進行了彈性屈曲分析、考慮非線性的彈塑性屈曲分析、以及在低周往復循環(huán)荷載作用下的滯回性能分析,為橫置蜂窩形截面鋼板剪力墻的設計和實際應用提供參考。 1.按照試驗模型建立有限元驗證模型。對分析過程中內填鋼板的變化進行分析,并通過將有限元軟件的分析結果與試驗結果對比來驗證有限元模型的正確性,為以后對橫置蜂窩形截面內填板的研究奠定基礎。 2.通過改變橫置蜂窩形截面鋼板剪力墻內填鋼板的參數(shù)如寬高比、高厚比、波峰(波谷)段長度、斜長度段長度和波高,對其進行彈性屈曲分析,無論參數(shù)如何變化其彈性臨界屈曲荷載遠大于相同厚度的平鋼板剪力墻。 3.在單調位移加載的條件下進行變參數(shù)彈塑性屈曲分析,可知橫置蜂窩形截面鋼板剪力墻具有較高的極限水平承載力,較高的初始剛度,當橫置蜂窩形截面內填鋼板部分發(fā)生屈曲變形后,雖然承載力有所下降,但仍具有較好的延性。 4.由在低周往復循環(huán)加載所得到的滯回曲線來看,橫置蜂窩形截面鋼板剪力墻有很高的初始剛度,滯回環(huán)比較飽滿,很好的能量耗散能力和較好的延性性能。
[Abstract]:Based on the research on the existing data of steel plate shear wall, this paper presents a defect that the transverse honeycomb steel plate shear wall (THSS-SPSW) is formed by combining two folded plates to improve the stability of thin steel plate shear wall outside the plane. In this paper, the elastic buckling analysis of steel plate shear wall with transverse honeycomb section is carried out by means of finite element numerical analysis method. The nonlinear elastoplastic buckling analysis and hysteretic behavior analysis under low cycle reciprocating cyclic load are considered. It provides a reference for the design and practical application of transverse honeycomb steel plate shear wall. 1. The finite element verification model is established according to the test model. This paper analyzes the change of the inner filling steel plate during the analysis process, and verifies the correctness of the finite element model by comparing the results of the finite element software with the test results. To lay a foundation for the further study of the transverse honeycomb section of the inner fill. 2. The elastic buckling analysis was carried out by changing the parameters such as width to height ratio, height to thickness ratio, length of peak (trough), length of oblique length and wave height of steel plate filled in shear wall with transverse honeycomb section. No matter how the parameters change, the elastic critical buckling load is much larger than that of the flat steel plate shear wall of the same thickness. Under the condition of monotone displacement loading, the elastic-plastic buckling analysis of variable parameters is carried out. The results show that the transverse honeycomb steel plate shear wall has higher ultimate horizontal bearing capacity and higher initial stiffness. After buckling deformation of the steel plate with transverse honeycomb section, the bearing capacity of the steel plate decreases, but it still has a good ductility. 4. According to the hysteretic curves obtained by low-cycle cyclic loading, the transverse honeycomb steel plate shear wall has high initial stiffness, full hysteretic loop, good energy dissipation ability and better ductility.
