PY - 2020 DA - 2020/12/21 TI -重要双向动态激励下响应控制Base-Isolated建筑SP - 8830460六世- 2020 AB -下结构的安全问题和posthazard功能重要场景中的一些重大挑战当前动态和快速增长的城市环境。本文以多层基础隔震建筑为研究对象，研究了地震与爆震地震动独立多灾害情景下的隔震结构。在双向多风险激励下，对装有层压橡胶支座(LRB)、铅-橡胶支座(N-Z)、纯摩擦(PF)、摩擦摆系统(FPS)和弹性-摩擦基础隔振器(R-FBI) 5种隔振系统的多层建筑模型进行了评估。对多层建筑隔震系统的适用性及其关键参数进行了评价。此外，还评估了上部结构阻尼和层数等上层结构特性的影响。文中还介绍了双向灾害对固定基础建筑的影响，以供比较。给出了基础隔震建筑的关键响应量，并对不同隔震系统的关键响应量进行了比较。通过参数化研究，研究了地震和BIGM多重灾害情况下隔震系统重要参数对建筑物防护的影响，给出了隔震系统响应量的变化趋势。 The results of the investigation show that the behaviors of the buildings equipped with various isolation systems are different for the two hazards. Moreover, the influences of the key parameters of the isolation systems are found to be different for various hazards. Therefore, the selection of design parameters of isolation systems shall be made with due consideration of the influence of multiple hazards. Additionally, the influence of the properties of the superstructure, such as the number of stories and the damping of the superstructure, on the behavior of the base-isolated buildings under the multihazard loading, is presented.
