Recently, the use of PC(Precast Concrete) structure is increasing due to quality assurance and process shortening. In this study, we proposed a PPC method that improved the seismic performance of Half PC method by connecting the cast iron of PC wall to the foundation anchor using sleeve. In addition, the inner and outer PC walls are fabricated as one body, and the PPW method suitable for the high wall structure is proposed.
