摘要:
大量的试验数据表明,铅芯橡胶支座的滞回曲线与加载时程密切相关.目前现有的铅芯橡胶支座恢复力模型中都没有考虑加载时程基础上的应变滞回特性,针对铅芯橡胶支座的这一特性,提出了铅芯橡胶支座的"扁环"效应,根据双拐点原则建立了考虑加载时程应变滞回特性的剪切弹塑性的"扁环"效应恢复力模型,并对提出的恢复力模型进行了静力试验验证.试验结果表明:作者提出的"扁环"效应能很好地描述铅芯橡胶支座加载时程的应变滞回特性,"扁环"效应恢复力模型合理、精确,适合于精确的非线性时程分析.
Abstract:
A large number of test data show that the hysteresis curve of the lead-core rubber support is closely related to the loading time history. At present, the existing recovery force model of lead-core rubber support does not consider the strain hysteresis characteristics based on the loading time course, in view of this characteristic of the lead-core rubber bearing, the "flat ring" effect of the lead-core rubber support is proposed, and the "flat ring" effect of the shear elastic plastic "flat ring" effect considering the loading time course strain hysteresis characteristic is established according to the principle of double inflection point, and the proposed restoring force model is verified by static test. The experimental results show that the "flat ring" effect proposed by the author can well describe the strain hysteresis characteristics of the loading time history of the lead-core rubber support, and the "flat ring" effect recovery force model is reasonable and accurate, which is suitable for accurate nonlinear time history analysis.
