发布时间：2018-09-14 12:42
【摘要】：通过对以往钢板剪力墙现有资料的研究，本文提出了一种通过将两个折板组合形成的横置蜂窝形截面钢板剪力墙（THSS-SPSW），来改善薄钢板剪力墙平面外的稳定性较差的缺陷。本文采用有限元数值分析方法对横置蜂窝形截面钢板剪力墙进行了弹性屈曲分析、考虑非线性的弹塑性屈曲分析、以及在低周往复循环荷载作用下的滞回性能分析，为横置蜂窝形截面钢板剪力墙的设计和实际应用提供参考。 1.按照试验模型建立有限元验证模型。对分析过程中内填钢板的变化进行分析，并通过将有限元软件的分析结果与试验结果对比来验证有限元模型的正确性，为以后对横置蜂窝形截面内填板的研究奠定基础。 2.通过改变横置蜂窝形截面钢板剪力墙内填钢板的参数如宽高比、高厚比、波峰（波谷）段长度、斜长度段长度和波高，对其进行弹性屈曲分析，无论参数如何变化其弹性临界屈曲荷载远大于相同厚度的平钢板剪力墙。 3.在单调位移加载的条件下进行变参数弹塑性屈曲分析，可知横置蜂窝形截面钢板剪力墙具有较高的极限水平承载力，较高的初始刚度，当横置蜂窝形截面内填钢板部分发生屈曲变形后，虽然承载力有所下降，但仍具有较好的延性。 4.由在低周往复循环加载所得到的滞回曲线来看，横置蜂窝形截面钢板剪力墙有很高的初始刚度，滞回环比较饱满，很好的能量耗散能力和较好的延性性能。
[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.
