摘　　要：为研究小剪跨比喷涂混凝土夹芯剪力墙的抗震性能,完成了3个剪跨比为1.03试件的拟静力试验。结果表明:钢丝网架聚苯夹芯板两表面的喷涂混凝土、边缘构件能够共同工作;试件的破坏形态为弯-剪破坏;设置边缘构件,可显著提高小剪跨比夹芯墙的弹塑性变形能力及耗能能力。To study the seismic behavior of sprayed concrete sandwich shear walls with low shear -span ratio , quasi-static tests on 3 specimens were carried out .The test results indicated that the concrete sprayed on both surfaces of the steel wire mesh framed by expanded polystyrene panel and the boundary elements work together as a unit .The wall specimens failed in bending-shear .The boundary elements enhanced the elastic-plastic deformation capacity and energy dissipation capacity of the specimen obviously .
