嵌入单个蝴蝶形钢板剪力墙的自复位结构体系的抗震性能研究

Study on Seismic Performance of Self-Centering Structure Embedded with Single Butterfly Steel Plate Shear Wall

在蝴蝶形钢板剪力墙研究的基础上设计了单个蝴蝶形钢板剪力墙。对单个蝴蝶形钢板剪力墙构造和原理进行了说明,研究单个蝴蝶形钢板剪力墙嵌入自复位钢框架中的滞回曲线、骨架曲线、刚度退化、承载力退化、耗能和复位性能。分析结果表明,不含钢板的自复位钢框架自复位效果较好,框架不耗能,可以用于自复位结构体系的研究。当单个加劲蝴蝶形钢板剪力墙嵌入到自复位钢框架中,随着高宽比的变化,结构的滞回性能、承载力峰值及稳定性、耗能和结构残余位移角影响程度较小,可以为设计单个蝴蝶形钢板剪力墙的设计提供参考。

A single butterfly shaped steel plate shear wall is designed on the basis of butterfly shaped steel plate shear wall research. The structure and principle of the single butterfly steel plate shear wall are explained. The hysteresis curve, skeleton curve, stiffness degradation,bearing capacity degradation,energy dissipation and self-centering performance of single butterfly shaped steel plate shear wall are studied in the self-centering frame. The analysis results show that the frame without steel plate self-centering effect is good, and the frame does not dissipate energy, so it can be used in the study of self-centering strueture.A single butterfly shaped steel plate shear wall is embedded in a self-centering steel frame. With the variation of the ratio of height-to-width, the hysteresis performance of the structure, the peak value and stability of the bearing capacity, the energy consumption and the residual displacement angle of the structure are little. It can provide a reference for the design of a single butterfly shaped steel plate shear wall.
