| 摘 要： | 本文严格按照中国规范设计出典型的带转换层部分框支剪力墙钢筋混凝土结构,通过弹塑性分析程序IDARC2D对该结构进行多个地震动作用下的大震弹塑性时程分析,得到结构及各个构件的反应量的统计特征,再参照美国基于性能抗震设计规范ASCE-41-06的结构与构件变形限值作为性能指标,计算出结构和各个构件的可靠度和可靠指标,作为评价结构抗震性能的标准,总结归纳出基于概率和位移的抗震设计方法的思路.最后运用该方法,对7、8度烈度区的框支剪力墙结构进行可靠性分析,通过对比分析,研究考虑内力增强措施、层间位移角控制条件、竖向构件轴压比限制条件、层刚比控制准则和竖向构件最小配筋率等因素对不同抗震烈度区的框支剪力墙结构的可靠性的影响,从而评价中国规范抗震措施和构造措施的有效性.

| Abstract: | A typical partially frame-supported shear wall structure with transfer story is strictly designed in accordance with Chinese code.Inelastic time-history analysis under rare earthquake with several seismic ground motions is carried out by the program IDARC2D,from which the statistical characteristics of structural and component's responses can be obtained.By taking the deformation limits of ASCE-41-06(American performance based seismic design code) as a reference,the reliability indexes of the structure and ... |
