This research program, which involves collaboration between the University of Maryland and the Universidad Nacional Autonama de Mexico (UNAM), will utilize the Random Decrement Technique to determine the damping properties of soil at different strain levels using measured seismic records. The ability to determine damping properties in-situ will permit a more reliable calculation to be made of site response to earthquake loading.

该研究计划涉及马里兰州大学与墨西哥大学Nacional Autonama de Mexico（UNAM）之间的合作，该研究将利用随机减少技术来使用测量的震震记录来确定不同应变水平下土壤的阻尼特性。 原位确定阻尼性能的能力将允许对地震负载的现场响应进行更可靠的计算。
