摘　　要：为研究预制单面叠合剪力墙的抗震性能,按1∶1比例制作了1个足尺现浇剪力墙构件和2个不同水平接缝预制单面叠合剪力墙构件,完成了拟静力试验。试验结果表明:单面叠合剪力墙与现浇剪力墙的受力过程、破坏模式基本相同,抗震指标相近,具有较好的抗震性能;单面叠合剪力墙的承载力接近现浇剪力墙;单面叠合剪力墙的耗能能力优于现浇剪力墙;单面叠合剪力墙试件中,搭接区有螺旋筋约束和无螺旋筋约束试件的抗震性能指标相差不大;单面叠合剪力墙的预制部分与现浇混凝土能够协同工作。总体而言,单面叠合剪力墙具有良好的抗震性能,能等同现浇设计,可在抗震设防地区推广使用。In order to study the seismic behavior of prefabricated single-face superposed shear walls,one cast-in-place shear wall specimen and two prefabricated single-face superposed shear walls with different horizontal connection were designed according to 1:1 full-scale,and the quasi-static test was completed.Test results indicate that the mechanical behavior and failure mode of the single-face superposed shear walls and the cast-in-place shear wall are basically the same,with similar seismic indexes and good seismic performance.The bearing capacity of single-face superposed shear walls are close to that of the cast-in-place wall.The energy dissipation capacity of single-face superposed shear walls are better than that of cast-in-place shear wall.The seismic indexes of the specimens with constrained steel spirals in overlap zone and without spiral bars in overlap zone are similar.The prefabricated parts and the cast-in-place concrete part of the single-face superposed shear walls can work together very well under loading.In general,single-face superposed shear walls show good seismic performance,which can be equivalent to cast-in-place design,and can be applied in seismic regions.
