［摘要］北京某高层钢结构住宅采用框架结构，结构纵横向布置墙板式阻尼器。采用等效支撑模型（PKPM）和弹簧模型（ETABS）对结构在多遇地震作用下的响应进行分析，采用弹簧模型（ETABS）对结构在罕遇地震作用下的结构响应进行分析。分析结果表明：1）等效支撑模型和弹簧模型可以较好地模拟墙板式阻尼器在结构中的作用；2）采用墙板式阻尼器后，结构在多遇地震下和罕遇地震作用下的抗震性能得到提高；3）多遇地震作用下，墙板式阻尼器为结构提供抗侧刚度，使结构的层间位移角满足规范要求，满足“小震不坏”的设计目标；4）罕遇地震作用下，结构的层间位移角满足规范要求，部分框架梁产生塑性铰，而框架柱始终保持弹性，能够达到“大震不倒”的设计目标；4）墙板式阻尼器在罕遇地震作用下屈服耗能，可为结构提供附加阻尼比。

Abstract: A high-rise steel frame building in Beijing was installed with wall type dampers. The seismic performance of the building was studied on structural under the frequent earthquakes respectively with programs PKPM and ETABS, and under the rare earthquakes respectively with programs ETABS. The results indicate that, equivalent structure model and spring model could preferably simulate wall type dampers’ function in structure. Esmic property of the structural under the frequent and rare earthquakes was increased by using wall type dampers. Under the frequent earthquake, the structure can achieve the design goal of “not damage under the frequent earthquake” considering the story drift meets the specification limits because of improving lateral stiffness by installing the dampers. Under the rare earthquakes, the structure can achieve the design goal of “no collapse under the rare earthquake” considering that the story drift meets the specification limits, part of frame beams produce plastic hinge, and frame columns generally keep elastic. The wall type dampers can yield and provide energy dissipation under the rare earthquake, then providing additional damper ratio. 

Keywords: energy dissipation; wall-type damper; lateral stiffness; simplify calculating way
