Research on the performance of semi grouting sleeve connection for cantilever prefabricated components
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.
