摘　　要：为研究含三明治保温夹芯外墙挂板的混凝土框架结构的抗震性能,进行了2榀足尺混凝土框架结构的低周往复荷载试验。2榀框架分别为纯现浇钢筋混凝土框架和含三明治保温夹芯外墙挂板的框架。根据两个试件的低周往复试验结果,对试件的刚度、承载力、延性及耗能能力进行综合评估。研究表明,含三明治保温夹芯外墙挂板的混凝土框架结构具有良好的抗震性能。考虑三明治保温夹芯外墙挂板后,结构的刚度提高约20%,结构的承载力变化不明显。试验中结构的最大层间位移角为1/16,此时三明治保温夹芯外墙挂板与框架梁连接处仍未出现明显破坏现象,并且三明治保温夹芯外墙挂板整体保持完好,说明在大震下结构发生大变形时三明治保温夹芯外墙挂板与主体结构的连接能够满足抗震设计要求。In order to investigate the influence of exterior sandwich cladding walls on the seismic behavior of the frame structure,two full-scale frames with and without exterior sandwich cladding walls are tested under cyclic loading. The stiffness,load-bearing capacity,ductility and energy-consuming capacity of the two test specimens are comprehensively evaluated based on the results of reversed cyclic loading tests. Satisfactory seismic behavior of the frame structure with exterior sandwich cladding walls is verified by the test results. The stiffness of the structure increased 25%,the yield load increased 19% after considering the exterior sandwich cladding walls. The connections between exterior sandwich cladding walls and beam connections have no noticeable phenomenon of failure and the exterior sandwich cladding walls remain intact when the inter storey displace angle reaches 1 /16,indicating that the connection details of the exterior sandwich cladding walls can meet the design requirement under rare earthquake.
