摘要 本文以单层钢框架模型为研究对象,采用初始位移起振法对空腔顶端施加初始偏离位移,突然释放后使构件产生自由振动,通过试验模态分析软件计算相应的阻尼比,并应用EDEM离散元软件进行颗粒阻尼主要影响参数(质量比)的模拟分析。 In this paper, a single-layer steel frame model is studied, and the initial displacement of the cavity is applied to the initial displacement of the cavity. EDEM discrete element software is used to simulate the parameters (mass ratio) of particle damping.
