摘    要:为了促进减震技术的应用,提出了一种基于位移型阻尼器力学模型和结构力学特征的消能减震设计方法。此方法避免了传统消能减震设计方法中多自由度体系与等效单自由度体系的相互转化,面向多自由度体系进行主体结构、阻尼器、连接构件一体化减震设计,与抗震设计规范和设计流程相衔接,具有较好的适用性。利用所提出的消能减震设计方法,使用墙式连接金属阻尼器,对1个8度抗震设防的4层钢筋混凝土框架原型结构进行了减震设计,得到墙式连接金属阻尼器减震结构,采用OpenSees对其进行了9度罕遇地震作用下的弹塑性时程分析,验证了所提出的减震设计方法的有效性。

关 键 词:框架结构  消能减震  减震结构  金属阻尼器  减震设计

Abstract:A design method of energy dissipation based on the mechanical models of displacement-based dampers and the main structure was proposed to facilitate the application of energy dissipation technology. The proposed method does not involve the transformation process between the multi-degree-of-freedom (MDOF) system and the equivalent single-degree-of-freedom (SDOF) system that is usually employed by traditional design methods. The design of the main structure, the dampers, and the connections is all included in the proposed procedure, making it well adapted to the design code and the existing seismic design process in China. A four-story reinforced concrete (RC) frame prototype structure designed for intensity VIII was selected and wall-connected metallic dampers were used to improve the seismic performance of the structure based on the proposed method. Nonlinear time history analyses under maximum considered earthquakes of intensity Ⅸ were conducted using OpenSees. The results demonstrate the effectiveness of the proposed design method of energy dissipation.
Keywords:frame structure  energy dissipation and vibration control  controlled structure  metallic damper  energy dissipation design
