Abstract Precast concrete walls can be one of solutions to quickly build the core structure in modular buildings. The horizontal connection of PC load-bearing wall requires vertical continuity across joints to acquire the strength and stability of the structure. To achieve continuity, the horizontal joints are designed as an emulative connection which performs similarly to monolithic wall of cast-in-place structure. A common method of emulative detailing in the horizontal connection between PC walls is the use of splice sleeve, known as mechanical splices. In this study, the wall shoe, a temporary connector, which is necessary for construction safety when assembling PC walls and the splice sleeves that is able to secure vertical continuity are investigated experimentally in consideration of field conditions, and compared with the strength according to structural design codes.
