| 摘 要： | 介绍了IDA方法的基本原理和分析步骤，采用Etabs软件对12个不同设防烈度、不同层数的高层剪力墙结构进行增量动力分析，给出了各结构模型在不同性能水平的最大层间位移角，并探讨了抗震设防等级和高度对剪力墙结构抗震能力的影响。研究表明，随着抗震设防等级的提高，结构的抗震能力会有显著的提升，而随着结构高度的增加，结构的抗震能力会相应降低。

| Abstract: | The basic principles and analytical steps of the IDA method are introduced in this paper. The Etabs software is used to perform incremental dynamic analysis on 12 high-rise shear wall structures with different fortification intensities and different layers, and the maximum layers of each structural model at different performance levels are given. The maximum inter-layer displacement angles of various structural models at different performance levels are given, and the influence of seismic fortification grade and height on the seismic performance of shear wall structures is discussed. Our results show that with the increase of seismic fortification level, the seismic capacity of the structure is significantly improved, and with the increase of the structure height, the seismic resistance of the structure is reduced accordingly. This conclusion is useful in providing a strong scientific basis for studying the earthquake damage and loss of engineering structures. |
