摘要
为研究剪切钢板阻尼器抗震性能及其影响因素,设计不同开孔形式、肢宽和肢高剪切钢板阻尼器,并进行数值模拟分析。对含剪切钢板阻尼器的自复位结构进行分析,研究阻尼器与预应力对自复位结构抗震性能的影响。研究结果表明,与相同肢宽、肢高的长孔和椭圆孔阻尼器相比,菱形孔阻尼器耗能效率最高,且肢高越小,肢宽越大,耗能效率越高;采用剪切钢板阻尼器的自复位结构滞回曲线呈典型的旗帜形特征。
It was designed that the steel shear panel dampers with different hole patterns,limb width and limb height to study the anti-seismic behavior and the effects of various parameters,and carried out numerical simulation analysis. The self-centering structures with steel shear panel dampers was studied,and the influences of the dampers and the prestress were analyzed. The results show that compared with the long hole and elliptical hole dampers with the same limb width and limb height,the diamond hole damper has the highest energy consumption efficiency. When the limb height is smaller and the limb width is larger,the energy consumption efficiency is higher. The hysteretic curve of the self-centering structure with steel shear panel dampers presents typical flag shape.
