This chapter provides a comprehensive overview of precast concrete (PC) shear wall technology, with a particular focus on fully assembled and assembled monolithic precast concrete shear walls. Additionally, the chapter reviews both domestic and international research, emphasizing China’s commitment to prefabricated buildings as part of national policies aimed at promoting green and low-carbon development. Moreover, the chapter discusses the integration of PC shear walls with residential structures to effectively address housing shortages and labor resource constraints. Furthermore, it categorizes PC shear walls according to their seismic resistance mechanisms and explores various connection technologies, such as post-stressed and bolted connections. Finally, the chapter outlines the future development direction of PC shear wall technology in China, underscoring the critical need for innovation and optimization to meet the increasing demands of high-rise residential buildings.
