摘　　要：通过４种外径相同但铅芯直径不同的８个铅－橡胶阻尼器的低周往复水平荷载试验，研究影响铅－橡胶阻尼器性能的主要因素，得到了这种阻尼器的初始刚度、屈服刚度和等效阻尼比的变化规律。试验结果还表明，铅－橡胶阻尼器即使在很小的剪切变形下也具有较高的耗能能力。lead-rubber dampers which have the same external diameter and 4 kinds of lead diame ters are tested under cyclic loading to investigate the main factors affecting the capability of the damper.The primary rules for the variation of the initial stiffness, the yield stiffness and the equiva lent damping ratio are obtained. The test results showed that the dampers could offer rather high damping even when they undergo very little shear deformations
