| 摘 要： | 提出了一种新型土坯墙房屋，对新型土坯墙房屋承重墙体的受力及抗震性能进行试验研究。设计三片新型土坯墙试件，研究土坯墙体在竖向荷载和反复水平荷载作用下的破坏过程、破坏形态、滞回曲线和骨架曲线特征以及墙体水平承载力和变形能力等，同时，研究新型构造措施对土坯墙抗震性能的作用。试验表明：新型土坯墙体的破坏模式与配筋混凝土小型空心砌块相似，土坯墙体具有良好的承载力和变形能力。新型构造措施对墙体整体抗震性能作用明显，其连接构造至关重要。与计算结果比较得出，在建筑抗震概念设计原则指导下，抗震设防7度区采用新型土坯墙建造二层房屋具有可行性。

| Abstract: | A new adobe wall structure was proposed and mechanisms and seismic behavior were studied. Three pieces of the specimen of the new adobe wall structure were designed. Vertical loads and low cycle horizontal loads were applied on the specimen in order to study the failure process, failure mode, hysteretic curve and skeleton curve feature. The horizontal bearing capacity and deformation capacity of the wall were also examined. Meanwhile, attention was paid to the influence of the seismic details of the wall structure on anti-seismic capacity. Test results show that the failure mode of the new adobe wall is similar to that of reinforced concrete masonry wall. The new adobe wall has favorable bearing capacity and deformation capacity. In addition, its anti-seismic performance is affected by the new seismic measures, in particular the connection. Compared with the theoretical calculation results, it is feasible to build a two-story structure housing by the new adobe wall in the 7 degree fortification regions. |
