摘　　要：为研究新疆农村装配式轻钢-沙漠砂轻骨料混凝土剪力墙结构墙肢中钢丝替代钢筋的可行性,以及检验各墙肢在水平地震作用下的抗震性能和破坏形态是否符合预期的多道抗震设防工作目标,对2个边缘墙、2个窗间墙、1个窗下墙及1个普通钢筋混凝土剪力墙试件进行拟静力试验,对比分析各试件的滞回曲线、骨架曲线、位移延性、耗能能力和承载能力。结果表明:边缘墙、窗间墙及普通钢筋混凝土剪力墙试件发生延性的压弯破坏,窗下墙试件发生脆性的剪切破坏;窗间墙与普通剪力墙在配筋率相同的条件下抗震性能指标接近,剪力墙中钢丝可代替钢筋;经比较,边缘墙试件极限位移角、延性系数、黏滞阻尼系数值最大,分别为1/50、3.37和0.163,其抗震性能最优,窗间墙试件次之,窗下墙最差,符合预期的工作目标;边缘墙、窗间墙可按偏心受压构件的正截面计算理论计算其水平受荷承载力。Seismic performance of rural building has posed a serious threat to the production and life of rural regions,particularly for some local characteristics of frequent earthquakes,cold climate,widespread desert,scattered distribution of rural buildings,and shortage of construction technology,such as in Xinjiang,western China.Therefore,the new type of prefabricated structure was demanding more and more urgently,to construct the high-quality living buildings with excellent seismic performance and heat preservation,while easy to gain architected materials and industrialized implementation.People living in a rural environment need to be prepared in the event of emergency.It is also significant to know the safety features in an apartment building,to keep the living and property as safe as possible.Specifically,the sparse materials environments can be a great challenge during the construction of houses in scattered habitations,such as highland desert in Xinjiang.These regional characteristics and technical requirements make it difficult to improve the seismic fortification level of villages and towns.In this study,a feasible shear wall structure was proposed in detail with a new lightweight aggregate concrete of precast light steel-desert sand,suitable for 1-2 story rural buildings in Xinjiang areas.The main purpose of seismic performance can be expected as the whole structural deformation of three kinds of wall panels for the resistance to earthquakes,particularly under the action of multiple earthquakes.The specific experiments can be carried out to meet the required needs of the region:under the action of fortification and rare earthquake,the separation of vertical joints between the walls,the shear failure of the lower wall below the windows,the bending damage of the walls between the windows,the dissipated seismic energy of the whole building together,thereby to ensure that the edge wall was not seriously damaged.A quasi-static test was conducted for two edge walls,two walls between windows,one wall under the window,
