Abstract
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.
