［摘要］通过对3榀几何相似比为1/2的中高层生态复合墙体模型进行在水平低周反复荷载作用下的抗震性能试验，研究复合墙体在低周反复荷载作用下的受力特点和破坏机制，对比分析其承载力、滞回特性、延性、强度退化、刚度退化等抗震性能。试验结果表明：内填砌块、框格、隐形框架在试验的弹性阶段、弹塑性阶段、破坏阶段依次发挥作用，使复合墙体具有多道抗震防线；墙体破坏后，墙体的层间位移角在1/58～1/44之间，均未出现倒塌现象；内置型钢可有效提高生态复合墙体的承载力和变形，为生态复合墙结构体系向中高层建筑领域的应用与推广提供了理论依据。

Abstract: This study was conducted on the seismic performance of three middle-high ecological composite walls whose scales are 1∶2 entirely, and a comparative study was conducted under reversed cyclic loading. Emphasis was put on the evaluation of the failure mechanism, bearing capacity, hysteretic loops, displacement ductility, deterioration of strength and stiffness of ecological composite walls under seismic loads. The experiment results showed that the filled blocks, ribbed grids and end frames in ecological composite walls played a role in turn in elastic stage, elastic-plastic stage and failure stage of the experiment, which indicated that the ecological composite wall has several seismic defending lines. The collapse of three middle-high ecological composite walls whose story drift angles were between 1/58 and 1/44 did not appeared. Shaped steel embedded in the ecological composite wall could effectively improve the bearing capacity and deformation characteristics of ecological composite walls. Theoretical basis was provided for application and popularization of ecological composite wall structure in middle-high building.

Keywords: middle-high ecological composite wall; reversed cyclic loading; failure mechanism; seismic performance
