| 摘 要： | 随着人们对地震震害的深入了解,PBSD越来越受到重视,美国、加拿大已经对混凝土小型约束砌体结构进行大量的研究,并将PBSD思想纳入结构抗震设计相应规范中,但是我国对于混凝土小型约束砌体结构的研究并不多,试验数据很少。整理了94个约束混凝土小砌块墙片试验数据,考虑权重,统计出加权延性系数平均值,开裂位移角、极限位移角平均值,给出墙片高度与开裂位移角、极限位移角的关系式,并给出约束混凝土小砌块墙片归一化恢复力模型,为约束混凝土小砌块结构基于性能抗震提供参考。 |
| 关 键 词： | 混凝土小型约束砌体 延性系数 开裂位移角 极限位移角 恢复力模型 |

| Abstract: | Recently,the method of performance-based seismic design has received more and more attention,a lot of research on performance-based seismic of concrete small block restrained masonry construction has been studied in foreign,but in china,less research is done,test data is less.In this thesis,arranging ninty-four walls test data,considering the weight,get ductility coefficient,yield displacement angle and extreme displacement angle,give the corresponding formula,meanwhile give resilience model,provide reference for performance-based seismic design. |
| Keywords: | concrete small restrained masonry ductility coefficient yield displacement angle extreme displacement angle resilience model |
