| 摘 要： | 研究了设置摩擦减振装置的多层建筑结构地震反应能量特点.首先建立了摩擦阻尼器的力学模型和结构-阻尼器体系的动力分析模型.进一步地,提出了设置阻尼器的结构体系的能量评价准则.在此基础上以某多层建筑结构为工程背景,研究了在不同类型地震地面运动作用下,设置控制装置的结构体系的振动能量特点.分析表明所提出的能量标准可以有效地描述地震作用下受控结构的能量特点.

| Abstract: | The evaluation of energy characteristics of earthquake-excited building structures with seismic protection devices is actively carried out.The mechanical model of passive friction dampers is introduced;and a dynamic model of building-damper system is proposed.The evaluation criteria of energy responses are developed and applied to the earthquake response mitigation of a real multi-story building incorporated with friction dampers.A real building structure is taken for example to investigate the feasibility ... |
