A novel brace system with a displacement amplification mechanism for damper energy dissipation is proposed in this paper. Theoretical mechanism of the multi‐limb brace damper system (MLBDS) is established. Finite element models are established to confirm the effectiveness of the proposed system. The seismic performance of the MLBDS is compared with those of traditional brace damper systems. Comparison results show that MLBDS has an excellent energy dissipation performance. In addition, the dynamic responses of a high‐rise building with the MLBDS installed to seismic excitations are evaluated. The results show that the MLBDS can significantly reduce the dynamic responses of the high‐rise building under strong earthquakes.

使用多臂支撑阻尼器系统增强建筑物的抗震性能

提出了一种新型的具有位移放大机制的支撑系统，用于阻尼器的耗能。建立了多臂支撑阻尼系统（MLBDS）的理论机理。建立有限元模型以确认所提出系统的有效性。将MLBDS的抗震性能与传统的支撑阻尼系统进行了比较。比较结果表明，MLBDS具有出色的能量耗散性能。此外，还评估了安装了MLBDS的高层建筑对地震激励的动力响应。结果表明，MLBDS可以显着降低高层建筑在强烈地震下的动力响应。
