摘　　要：结合某高地震烈度区的实际工程项目,研究连梁阻尼器在剪力墙结构中的受力特点、设计方法,采用ETABS程序进行结构减震性能分析和弹塑性性能评估。连梁阻尼器在地震作用下不但可以成为剪力墙结构可靠的耗能构件,减小地震响应,还可有效地控制结构损伤模式,防止混凝土连梁的剪切破坏,减少混凝土构件的损伤,实现耗能构件震后的可更换性。建议采用设防烈度评估消能减震结构的性能,以“损伤控制”的概念进行设计。设置连梁阻尼器的剪力墙结构更容易实现结构构件中震少修的损伤控制目标。Based on the project in a high seismic intensity area,the mechanical behavior and design method of the shear wall structure with the coupling beam dampers were studied.The structural seismic energy dissipation performance and the elastoplastic performance were analyzed by using ETABS program.Coupling beam damper under earthquake can be a reliable energy dissipation component in shear wall structure,reduce the seismic response,effectively control the structural damage mode,prevent the shear failure of concrete coupling beam,reduce the damage of concrete components,and implement the function of replaceable coupling beam.It is recommended to use the precautionary earthquake intensity to evaluate the performance of energy dissipation and the concept of"damage control"should be used to design structures.The shear wall structure with coupling beam damper is easier to achieve the damage control target of minor structural repairs under the precautionary earthquake.
