摘　　要：本文采用自由衰减法,对两组橡胶集料混凝土及普通混凝土小型悬臂梁的阻尼比进行了测定。初步试验结果显示:测出的橡胶集料混凝土阻尼比较普通混凝土提高了很多,表明了在混凝土掺入橡胶微粒可增加阻尼的量值。Two kinds of concrete specimens, one is crumb rubber concrete （CRC） and the other is controlled concrete, are tested as a cantilever beam for measuring their damping coefficients by the free attenuation method. The preliminary results show that the damping coefficient for the former specimen is higher than the latter, indicating that adding rubber crumbs may help to increase the damping capacity for the concrete as well.

关 键 词：阻尼比 自由衰减 橡胶集料混凝土
