摘要
扩展散体单元法（ＥＤＥＭ）是结构倒塌模拟的一种方法。对于动力问题；ＥＤＥＭ的阻尼系数必须采用接近实际的取值。而 ＥＤＥＭ中常用粘滞阻尼的实质是Ｒａｙｌｅｉｇｈ阴尼，可通过已知的振型阻尼比确定阻尼系数。
Extended distinct element method (EDEM) is a method used to simulate the struc- ture collapse. The damping coefficient of EDEM for the dynamic analysis should reflect the be- havior of the real damping. The damping that is usually used in EDEM is Rayleigh damping in nature, which can be confirmed through the known damping ratio of the vibration mode.
