摘要
为促进采用半灌浆套筒连接的悬臂式预制构件的工程应用,从连接接头和构件 2 个层面对连接性能进行了深入的理论分析,建立了极限状态的分析模式并给出了套筒环向、纵向应变以及连接钢筋纵向变形的分析结果,同时提供了适用于悬臂式预制构件半灌浆套筒连接的设计与复核方法,其有效性经过了试验研究的验证.
Abstract
In order to promote the engineering application of cantilever prefabricated components connected by semi grouting sleeves,a deep theoretical analysis was conducted on the connection performance from the two levels of connection joint and component.A limit state analysis mode was established,and then the analysis results of sleeve circumferential strain,longitudinal strain and longitudinal deformation of connecting steel bars were provided.At the same time,a design and review method suitable for semi grouting sleeve connection of cantilever prefabricated components was provided.Its effectiveness has been verified through experimental research.
