| 中文摘要: |
| 本文结合TMD阻尼器与层间隔震技术各自工作特点，即隔震层可吸收一部分外界输入能量，避免TMD的质量过大影响施工，TMD可减小隔震层的位移，延长隔震装置的使用寿命，并基于振型分析结果提出两种混合层间隔震体系设计策略，对Benchmark模型的时程分析表明，混合控制策略可有效改善层间隔震体系的整体抗震性能，为类似建筑抗震设计提供有益参考。 |
| 英文摘要: |
| This paper combines the working characteristics of TMD damper and floor isolation technology, that is, the isolation layer can absorb a part of the external input energy, so as to avoid the excessive mass of TMD affecting construction, TMD can reduce the displacement of the isolation layer and extend the isolation device. Based on the results of the mode shape analysis, two design strategies for the mixed-story isolation system are proposed. The time history analysis of the Benchmark model shows that the hybrid control strategy can effectively improve the overall seismic performance of the floor-isolation system, which is a good example for the seismic design of similar buildings. |
