| 摘 要： | 混凝土小砌块约束砌体结构,由于加入芯柱、构造柱、圈梁,使结构整体性提高,因此具有较好的抗震性能和发展前景。通过整理94个混凝土小砌块约束砌体墙片试验数据,考虑权重,统计了混凝土小砌块约束砌体墙片延性系数,给出了延性系数与高度、延性系数比与高宽的关系,同时给出了层间开裂位移角、层间极限位移角公式,以及接近倒塌时混凝土小砌块约束砌体结构层间位移的计算公式,并与一个八层混凝土小砌块约束砌体结构的动力时程分析结果进行了对比,结果显示,最大误差在顶层,为17.7%,因此,所提层间位移计算公式是可以满足工程精度需要的,为混凝土小砌块约束砌体结构基于性态的抗震分析提供参考。 |

| Abstract: | Small concrete block confined masonry construction has better seismic performance and development praspect.By arranging test data of 94 small concrete constraint block masonry walls and considering the weight,this paper presents ductility coefficient of small block confined masonry walls and relationship between the ductility coefficient and height/height-width ratio and gives the formulas of storey crack and ultimate drift angles and the storey drift angle of structure close to collapse.Through an example,the maximum error of the formulas is about 17.7%,therefore,these formulas are credible.The formulas proposed give a reference to performance-based seismic design of small concrete block confined masonry structure. |
| Keywords: | reinforced masonry ductility yield displacement angle extreme displacement angle displacement between stories |
