摘要

通过对铅芯橡胶支座剪切弹塑性力学性能试验,发现铅芯橡胶支座的滞回曲线与加载时程密切相关,在同一水平应变下,水平剪切刚度随加载次数的增多有所减小,最后趋于稳定;在不同应变下,水平剪切刚度随应变的增大而减小.试验还表明铅芯橡胶支座不仅在大应变存在着小应变滞回特性,而且在小应变也存在着小应变滞回特性.
Based on the test of shearing elastic-plastic mechanical behaviour of leading rubber bearings,it was found that the hysteresis behaviour was closely correlated with loading history.The horizontal shear stiffness decreased with loading times when the level of strain was identical,and the stiffness became steady on the end.In the case of varying strain,the horizontal shear stiffness decreased with the strain.The test also showed that the small strain hysteresis took place not only with a large strain but also with small one.
