【摘要】 为实现变形指标——层间位移角在剪力墙结构基于性能的抗震设计中的应用,研究了层间位移角与构件变形之间的关系。首先,通过弹性分析得到了层间位移角与构件变形关系的计算公式。然后对不同楼层数的3个剪力墙结构进行了弹塑性时程分析,研究了结构在各性能状态下层间位移角与构件变形之间的关系。通过对计算结果的统计分析建立了弹塑性层间位移角与构件变形关系的计算公式。利用提出的方法可以直接、较为简便地将结构的整体变形转换为构件变形。更多还原

【Abstract】 The relationship between the element deformation and the story drift was studied to realize the application of story drift in performance-based seismic design of shear walls.Firstly,the equations to determine the relationship between the element deformation and the story drift was derived by elastic analysis.Secondly,the relationship between element deformation and the story drift at different performance level was studied on the basis of the elasto-plastic time history analysis of three shear wall structures with different stories.The equations for the relationship at inelastic stage were developed based on the statistical analysis of calculation results.The demands on the story drift can be converted into the deformation requirements for elements by using the proposed method conveniently.更多还原
