【摘要】：剪力墙一般应用于高层建筑结构当中,是承受水平作用(水平地震作用和风荷载)和竖向荷载的主要受力构件,在地震中发挥着至关重要的作用。目前,现有的普通钢筋混凝土剪力墙的抗震能力在诸多方面尚有不足,所以研制出一种更为有效的剪力墙是建筑工程界需要马上解决的问题。本文主要研究对象为内藏钢板剪力墙,这是一种新型组合形式的剪力墙,抗震性能更好,适应时代的发展。本文对该新型组合剪力墙进行了比较系统的非线性分析和理论分析。本文运用有限元软件ABAQUS建立内藏钢板剪力墙模型,通过分析顶点位移与底部剪力之间的变化规律,研究其在单调荷载和循环往复荷载作用下的非线性性能,并分析了方钢管边框柱对剪力墙结构构件非线性性能的影响。研究结果表明,内藏钢板剪力墙结构体系在单调荷载和低周循环荷载作用下的承载力性能和抗侧移能力都很好。剪力墙在设置方钢管边框柱之后,承载力、延性更佳；改变方钢管壁厚度,无法显著提高剪力墙的性能；在低周循环荷载作用下,内藏钢板剪力墙的滞回曲线饱满,耗能能力很好。
[Abstract]:Shear walls are generally used in high-rise building structures, which are the main members bearing horizontal (horizontal earthquake and wind load) and vertical loads, and play an important role in earthquake. At present, the existing reinforced concrete shear wall is still insufficient in many aspects, so the development of a more effective shear wall is a problem that needs to be solved immediately in the field of building engineering. The main research object of this paper is the steel plate shear wall, which is a new type of composite shear wall, which has better seismic performance and adapts to the development of the times. In this paper, the nonlinear analysis and theoretical analysis of the new composite shear wall are carried out systematically. In this paper, the finite element software ABAQUS is used to establish the model of steel plate shear wall. The nonlinear behavior of the shear wall under monotone load and cyclic reciprocating load is studied by analyzing the variation law between the top displacement and the bottom shear force. The influence of square steel tube frame column on the nonlinear behavior of shear wall members is analyzed. The results show that the bearing capacity and lateral displacement resistance of the steel plate shear wall system under monotone and low cycle loads are very good. The shear wall has better bearing capacity and ductility after the square steel pipe border column is installed, and the performance of the shear wall can not be improved significantly by changing the thickness of square steel pipe wall. Under low cycle cyclic load, the hysteretic curve of steel plate shear wall is full and the energy dissipation capacity is very good.
