Progress of Investigation on Seismic Behavior of Precast Concrete Shear Wall Structures(II):Structure Property Study

The importance of study on seismic behavior of precast concrete shear wall structures is described.Progress of investigation on seismic behavior of precast concrete shear wall structures is introduced,including investigation on large panel concrete structures,unbounded post-tensioned precast concrete wall structures(UPPCW structures),superimposed shear wall structures and other types of precast concrete shear wall structures.The design code and design method of precast concrete shear wall structures at home and abroad are introduced.It is concluded that large panel concrete structures and UPPCW structures have low energy dissipation capacity.The energy dissipation capacity of precast energy-dissipation shear wall structures and precast shear wall isolation structures are better than that of large panel concrete structures and UPPCW structures.It is suggested that the seismic behavior of precast energy-dissipation shear wall structures and precast shear wall isolation structures should be paid more attention to in future research work.
