摘要：

Given the extensive utilization of composite structures of ultra-high performance concrete (UHPC) and normal concrete (NC) in engineering applications, there has been a growing emphasis on studying the shear failure and mechanical properties analysis of the UHPC-NC interface. U-shaped studs assume a crucial role in reinforcing the UHPC-NC interface, so it is of great significance to analyze the shear failure of UHPC-NC interface with U-shaped studs. To directly observe the bonding failure process between studs and concrete and to determining the failure mechanism of the UHPC-NC interface with U-shaped studs, this paper establishs the three-dimensional finite element model to investigate the local damage evolution and the failure pattern of UHPC-NC incorporating U-shaped studs. The numerical analysis indicates the final failure pattern of the UHPC-NC interface with U-shaped stubs is the fracture of the U-shaped stud.
