摘要
阐述了预制钢筋混凝土剪力墙结构抗震性能研究的重要性和预制钢筋混凝土剪力墙结构抗震性能研究的最新进展。综述了国内外预制钢筋混凝土剪力墙结构设计规范以及设计方法的研究进展。指出常规预制装配式钢筋混凝土剪力墙结构的抗震性能较差,在地震作用下,主要靠结构构件连接处的损伤和结构构件损坏来消耗能量;无粘结后张拉预应力预制混凝土剪力墙结构,在地震作用下具有自恢复中心能力和良好的抗震能力,但该结构体系的耗能能力不足。认为在预制钢筋混凝土剪力墙结构中设置耗能减震元件,或将预制钢筋混凝土剪力墙结构设计成隔震结构,将有效提高预制钢筋混凝土剪力墙结构的抗震性能。该类预制装配式剪力墙结构的抗震性能有待于进一步研究。
The importance of study on seismic behavior of precast concrete shear wall structures is de- scribed. Progress of investigation on seismic behavior of precast concrete shear wall structures is intro- duced, including investigation on large panel concrete structures, unbounded post-tensioned preeast con- crete wall structures （UPPCW structures）, superimposed shear wall structures and other types o{ pre- cast 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 ener- gy-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 pre- cast energy-dissipation shear wall structures and precast shear wall isolation structures should be paid more attention to in future research work.
