摘要：
Partially encased composite (PEC) shear walls possess lower self-weight, higher ductility and more convenient construction than conventional reinforced concrete ones. In this paper, a comprehensive experimental program consisted of 6 specimens was carried out to investigate the seismic behavior of PEC shear walls with different axial compression ratios and shear-span ratios. The test results show that PEC shear walls are the typical compression-bending failure. The hysteretic curves are full, and the energy dissipation capacity is good. The ultimate displacement angle between stories was 1/56, which exceeded the code limit under rare earthquakes, indicating that the prefabricated partially encased composite shear walls have good deformability. With the increase of axial compression ratio, the stiffness and energy dissipation capacity of the specimens show a trend of first increasing and then decreasing, and the ductility decreases significantly. With the decrease of shear-span ratio, the bearing capacity and stiffness of the specimens are rapidly increased, while the energy dissipation capacity of the specimens is decreased and the rate of stiffness degradation is increased. © 2022 Chinese Vibration Engineering Society.
