Numerical Analysis of Prefabricated Column-Base Connections in Tunnels
Abstract Large shield tunnels with double decks inside have been developed rapidly for highway tunnels in China, and prefabricated structural members are applied frequently for their internal structures. Based on the engineering practice of Zhuguanglu tunnel in Shanghai, the mechanical performance of two different column-base connections is studied through three-dimensional numerical analyses. Results showed that: the specimen with grouted splice sleeve connection had the same load-bearing capacity as the specimen with cast-in-site connection. Plastic hinge appeared at the bottom of the columns in both cases, while the upper region of the grouted splice sleeve connection shows significant stress and severe plastic damage indicating a second plastic hinge.
