This chapter focuses on the restoring force model of emulative hybrid assembled precast concrete shear walls (EHSW), essential for seismic performance analysis. The restoring force model, represented by the hysteresis curve, captures key mechanical properties such as strength, stiffness, and ductility. The study proposes a quadrilinear skeleton curve model for EHSW under monotonic loading, identifying critical points (cracking, yield, limit, and failure) to describe the load–displacement relationship. Under cyclic loading, hysteresis rules are established, including unloading stiffness degradation and reloading paths. The model demonstrates good agreement with experimental hysteresis curves, accurately reflecting the load–displacement behavior and stiffness degradation of EHSW specimens. This research provides a theoretical foundation for seismic design and analysis of precast concrete shear walls.
