摘要
为改善普通剪切型软钢阻尼器在翼缘与连接板焊缝处应力集中问题,提出了一种翼缘弯折式剪切型软钢阻尼器。通过低周反复试验和ABAQUS有限元模拟,对阻尼器的基本力学性能和疲劳性能进行研究。数值模拟分析和试验结果大致贴合,改良后的阻尼器性能稳定,耗能效果明显,能进行较大位移的剪切变形,具有一定抗疲劳能力。该阻尼器构造简单易于制造,可为相关研究提供参考。
In order to improve the stress concentration at the weld between the flange and the connecting plate of traditional steel shear panel dampers,a new steel shear panel damper with bending flange was developed.The basic mechanical properties and fatigue performance of the damper were studied through low-cycle cyclic loading tests and simulation on the finite element soft ware ABAQUS.The results of numerical simulation is consistent with those of experiments approximately.The improved damper has stabilized performance,obvious energy dissipation effect,good shear deformation capacity,and has some fatigue resistance.The structure of the damper is easy to manufacture,which provides references for related research.
