摘　　要：为了便于生态复合墙体的进一步推广,在前期大量试验基础上,通过对1/2比例现砌加强肋生态复合墙体(XQCW-1)模型在低周反复荷载作用下的抗震试验,研究改变施工工艺后生态复合墙体的承载力、刚度、变形等抗震性能,并与标准密肋生态复合墙体(ECW-1)的受力特性作对比分析。试验结果及理论研究表明:现砌加强肋生态复合墙体在承载力、刚度等抗震性能方面较标准密肋生态复合墙体略有降低,但在偏远地区的新农村建设中可以避免现场吊装、运输等工程实际问题,满足结构设计要求、缩短施工周期、降低造价,且能非常简便地解决传统砌体结构的易开裂问题,具有广阔的应用前景。In order to facilitate further promotion of the ecological composite wall,the test of an ecological energy-saving composite wall with 1/2 scale under low-frequency cyclic loading is carried on based on the large amounts of the previous experiments of the group,the seismic performances of the wall,which is conducted by changing the construction technology based on the ecological nergy-saving composite wall,such as the bearing capacity,stiffness and displacement ductility are studied and compared with the previous standard multi-ribbed ecological composite walls.Test results and theoretical research show that the bearing capacity and stiffness of the site building stiffening ribs ecological composite wall are both lower than the previous standard multi-ribbed ecological composite walls.However,by applying the site building stiffening ribs,it can avoids some engineering problems of the new rural construction in remote areas,such as site lifting and transportation,which meets the design requirements.At the same time,it can shorten the construction period,reduce the cost and solve the cracking of traditional masonry structures easily.Therefore,the site building stiffening ribs ecological composite wall has broad application prospects.
