中文摘要：
简要论述了天然橡胶支座（LNR）的力学特性，通过不同温度、不同压应力、不同应变的相关性压剪试验研究了天然橡胶支座等效阻尼比的温度、压应力、应变相关性．试验结果表明常规条件下天然橡胶支座等效阻尼比在2％～3％之间，结合日本的相关资料及设计方法，隔震设计中可不考虑天然橡胶支座的粘滞阻尼．
英文摘要：
Machanical characteristics of linear natural rubber bearing is discussed in brief. By means of dependency compressive-shear testing in different temperature, compressive stress, strain, the equivalent damping ratio dependence of linear natural rubber bearing are researched. Based on the testing result, in normal condition, the equivalent damping ratio ranges from 2% to 3%. In view of the data and design method of Japan, the viscous damping of linear natural rubber bearing may not be considered in the seismic-isolation design.
