 ［摘要］对3个环筋扣合剪力墙试件及3个现浇剪力墙试件进行了平面外抗折试验，对比了二者的试验过程及现象，考察了其极限荷载，分析了其荷载-位移关系及应变-位移关系。试验结果表明：二者的破坏模式均为受弯破坏，但破坏位置不同，现浇试件的破坏位置在试件底部，环筋扣合试件的破坏位置在试件中部;环筋扣合试件内部钢筋均能够较好地传递应力，相同荷载下，环筋扣合试件顶部位移低于现浇试件；环筋扣合试件的极限承载力远大于现浇试件，表明环筋扣合试件剪力墙底部具备较高的面外抗弯承载能力，该连接形式的面外抗折能力是可靠的。

Abstract： In order to contrast the process and phenomena of the out-of-plane bending test, three specimens of annular closed reinforcement and three cast-in-place shear walls were carried out of two groups. The relationship between loading and displacement, strain and displacement was studied. The test results indicate that the failure mode of the two groups is both bending destruction, but its location is different. The cast-in-place shear walls located in its bottom and the annular closed reinforcement in the middle of the specimen. The reinforcement of annular closed reinforcement can transfer stress commendably. While under the same loading, the displacement at top of annular closed reinforcement specimen is less than that of the cast-in-place specimen. The ultimate bearing capacity of the annular closed reinforcement specimen is much larger than that of the cast-in-place specimen. It shows that the bottom of annular closed reinforcement specimen has a higher flexural bearing capacity, so this connection method is reliable.

Keywords： annular closed reinforcement；out-of-plane bending; ultimate load; loading-displacement curve
