摘　　要：本试验对4组混凝土灌芯纤维增强石膏板T形纵横墙节点构件进行了低周反复试验研究,分析了混凝土灌芯纤维增强石膏板T形节点构件在水平低周反复荷载和常竖向荷载共同作用下的抗震性能(包括承载能力、变形能力、刚度退化、滞回环和耗能能力)以及结构的破坏特征,并对不同配筋形式的构件作了相应对比分析,得出了混凝土灌芯纤维增强石膏板T形节点构件配置水平拉接筋形式可以取代配置箍筋形式和抗剪性能优于普通砌体纵横墙节点构件的结论,为混凝土灌芯纤维增强石膏板结构的纵横墙节点抗震设计提供一定的试验依据和理论指导。Tests of joint specimens of T type made of concrete-filled fiber-reinforced plasterboards under horizontal-low-cyclic loading with constant vertical loading were carried out. Fundamental seismic behavior (including carrying capacity, distortion ability, rigidity degeneration, load-displacement curve, etc) of such joints and the failure feature have been investigated. Based on those, different types of specimens are compared. It is concluded that the capacity against shearing force of the T joints is better than that of the clay soil brick joints. The conclusions present some testing basis and theoretical guidance of the seismic fortification design of the longitudinal and transverse wall joints made of concrete-filled fiber-reinforced plasterboard.
