摘要
提出一种套筒式全螺栓装配钢筋混凝土(reinforced concrete,RC)墙板,上、下墙板连接处采用高强螺栓-钢板组合结构形式,通过预埋套筒连接件,以实现结构的快速拼装。共设计4种试件,开展了水平推覆和滞回试验研究,获得了RC板破坏现象、滞回曲线、骨架曲线、刚度退化和耗能能力等抗震性能指标。结果表明:该试件在推覆和滞回试验中均具有较高承载力和刚度,整体稳定性较好;破坏主要集中在连接件角部,形成“X”形交叉裂缝带。增加盖板数量后,试件极限承载力提升了24%,刚度增加了17%;滞回曲线由反S形转变为梭形,耗能能力增加了16%。该新型连接可较好完成应力传递,满足墙板结构快速装配与安全要求,为该类型结构的应用提供技术支持。
Here,a sleeve-type all-bolt assembled reinforced concrete(RC)wallboard was proposed.Connection between upper and lower wallboards could adopt a high-strength bolt-steel plate composite structure.Sleeve connectors were pre-embedded to realize structure rapid assembly.4 types of specimens were designed,horizontal puchover and hysteresis tests were conducted for them to obtain their aseismic performance indexes of RC plate failure phenomenon,hysteresis curve,skeleton curve,stiffness degradation and energy dissipation capacity.The results showed that specimens have higher load-bearing capacity and stiffness in both pushover and hysteresis tests,and their overall stabilities are better;their damages are mainly concentrated at corners of connectors to form“X”-shaped intersecting crack zones;after increasing the number of cover plates,ultimate load-bearing capacities of specimens increase by 24%and their stiffnesses increase by 17%;their hysteresis curves change from inverse S-shape to shuttle shape to increase energy dissipation capacities by 16%;this new type of connection can effectively complete stress transmission,meet requirements of rapid assembly and safety of wallboard structures,and provide technical support for applications of this type of structures.
