［摘要］通過對(duì)3榀幾何相似比為1/2的中高層生態(tài)復(fù)合墻體模型進(jìn)行在水平低周反復(fù)荷載作用下的抗震性能試驗(yàn)，研究復(fù)合墻體在低周反復(fù)荷載作用下的受力特點(diǎn)和破壞機(jī)制，對(duì)比分析其承載力、滯回特性、延性、強(qiáng)度退化、剛度退化等抗震性能。試驗(yàn)結(jié)果表明：內(nèi)填砌塊、框格、隱形框架在試驗(yàn)的彈性階段、彈塑性階段、破壞階段依次發(fā)揮作用，使復(fù)合墻體具有多道抗震防線；墻體破壞后，墻體的層間位移角在1/58～1/44之間，均未出現(xiàn)倒塌現(xiàn)象；內(nèi)置型鋼可有效提高生態(tài)復(fù)合墻體的承載力和變形，為生態(tài)復(fù)合墻結(jié)構(gòu)體系向中高層建筑領(lǐng)域的應(yīng)用與推廣提供了理論依據(jù)。

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
