摘　　要：传统的装配式框架结构面对地震作用时是以“抗”为主,为了增强传统框架结构抗震耗能能力,提出一种带有耗能连接及内置RC墙板的装配式耗能RC结构体系。利用有限元仿真的方法建立装配式耗能RC结构模型,对模型底部施加了地震激励作用,考察结构在地震时程下的动力响应。其响应结果证实了内置阻尼器及RC墙板,能够消耗地震的能量,达到保护主体框架的目的。并且新结构体系能够实现“阻尼器→墙板→框架”的屈服顺序。The traditional prefabricated frame structure is mainly resistant to earthquake action.In order to enhance the seismic energy dissipation capacity of traditional frame structure,a prefabricated energy dissipation RC structure system with energy dissipation connection and built-in RC wallboard is proposed.In order to investigate the energy dissipation capacity and working mechanism of the new structure system,the finite element simulation method is used to establish the prefabricated energy dissipation RC structure model,and the seismic excitation is applied to the bottom of the model to investigate the dynamic response of the structure under the earthquake time history.The response results confirm that the built-in damper and RC wall panel can consume the energy of earthquake and achieve the purpose of protecting the main frame.And the new structure system can achieve the yield order of"damper→wallboard→frame".
