Seismic performance is basically required in precast shear wall. This study focuses on evaluation and improvement on precast shear wall seismic performance. By carrying out the finite-element simulation on a precast shear wall spatial model with new connector from a practical high-rise precast residential building, which was named as NPGCS and experimentally tested by low-cyclic reversed lateral loads in early studies, the performance results including strengths, stiffness, stress, and concrete damage ratio distributions were obtained, and the reliability of NPGCS spatial model was verified. According to the testing results, the finite-element simulation for the NPGCS spatial model is reliable and relatively accurate, especially for applying contact and beam elements into numerical analysis of precast interfaces and dowel shear actions, respectively. The strengths, stiffness, stress, and concrete damage ratio distributions from the simulation also supported the experimental results and conclusions.

A new method to infill the opening in the precast fabricated concrete shear wall was applied in China. In this paper, three geometrically identical precast fabricated shear wall specimens were constructed and tested under constant axial load and quasi-static cyclic lateral loading. The only difference among three specimens was the methods to infill the opening in the middle, the methods were respectively integration infill, masonry infill and without infill. The hysteretic curves, the skeleton curves, the failure process, the strain variation of reinforcement, the stiffness, the ductility and energy-dissipating capacity were obtained. The results and analysis showed that integration shear wall owns good seismic performance. Its bearing capacity, stiffness, energy-dissipating capacity are excellent while ductility is relatively poor. Masonry infilled wall and wall without infill also own good seismic performance.
