摘　　要：设计了一种新型的UHPC磷石膏夹芯保温剪力墙板,并按照FRP连接件不同锚固深度和是否现浇磷石膏保温层分成六组试件,并进行抗剪试验,研究了剪力墙的破坏形态、荷载-位移关系等。结果表明:试件的破坏形态主要是FRP连接件的剪切破坏而导致的试件破坏;连接件的锚固长度可以适当提升墙板的拉剪承载力,磷石膏保温层可以明显提升试件的抗剪承载力和减少试件开裂前的相对位移。A novel UHPC gypsum core insulated shear wall was designed,and six groups of specimens were divided according to different anchorage depths of FRP connectors and whether the gypsum insulation layer was cast-in-place.Shear tests were conducted to study the failure modes and load-displacement relationships of the shear walls.The results showed that the main failure mode of the specimens was shear failure of the FRP connectors,which led to the failure of the specimens.Increasing the anchorage length of the connectors could appropriately improve the tensile-shear capacity of the wall panels,and the gypsum insulation layer could significantly enhance the shear capacity of the specimens and reduce the relative displacement before cracking.
