Abstract When existing Reinforced Concrete (RC) framed structures are strengthened with Precast Concrete (PC) wall panels, a special connection is required that can accommodate the time-dependent deformation of the RC frame when using PC members made of the same size and resist a large shear force. In this study, we propose a connection that can solve both of these issues through overlapping anchors. The purpose of this study is to investigate and analyze the shear resistance of the overlapped anchor connections between the PC panel and the RC elements in modeling tests. A total of ten full-scale specimens of anchored connection models were constructed and push-out tested. Two anchor groups were installed in three concrete segments and overlapped in the connection of the specimens. The tested average shear strength of the overlapped anchored connections was 109% of the calculated values according to the American anchor design code. The results of this study show that the new anchored connection model can be analyzed using the American anchor design code. Therefore, we can predict the effect of the proposed connection, and it is expected that the design safety and construction practicability of the infill method will be improved using these connections.
