| 摘 要： | 提出了适合工程实际应用的"双功能"软钢阻尼器,对单圆孔型及双X型软钢阻尼器进行了拟静力往复加载试验,试验结果表明,两种阻尼器均具良好的滞回耗能特性;将两种阻尼器应用于实际工程中,成功地解决了薄弱层问题,同时给出了钢筋混凝土结构中安装"双功能"软钢阻尼器的设计过程;对装有软钢阻尼器的钢筋混凝土结构进行有限元三维仿真分析,结果表明,本文提出的软钢阻尼器对结构位移有较好的控制效果,具有在小震时为结构提供较大的初始刚度,大震时耗散地震能量的双重功能。

| Abstract: | The metallic dampers with "dual functions" are presented in this paper,and the quasi-static tests with the dampers are carried out.Design and fitting process of the reinforced concrete frame with dual functional metallic damper are introduced.A three-dimensional frame structure model is made with ADPL language in ANSYS program.Seismic responses of the structure with and without metallic damper are discussed and compared.The results show that the metallic dampers with "dual functions" presented here not only provide certain stiffness in normal using,but also are of good ability of the seismic energy dissipation. |

| Keywords: | metallic damper hysteric loop dissipative structure nonlinear seismic response |
