000021515 520__ $$2eng$$aThe use of prestressed precast concrete shear walls (PPCW) as the primary lateral force resisting system in seismic regions has been studied in previous researches. The PPCW structures could concentrate the deformation at the joints and use the unbonded prestressed tendons to provide restoring force to achieve self-centering capacity, thus the residual drift is rather small. In this paper, analytical models of 16-story PPCW frame-shear wall structures designed using displacement-based approaches were established using OpenSEES to study the influence of location of joints and number of joints under both cyclic loading and earthquake loading. Case study buildings were analyzed under three levels of seismic hazards. The comparison was made between the behavior of the PPCW structures and the conventional cast-in-place concrete shear wall (CIPW) structures including the inter-story drifts, shear force distribution, base moment distribution and concrete crushing stress at contact edges of rocking sections. The results indicated that higher mode effects were mitigated on shear and moment actions and residual drifts of buildings were negligible.
