[摘要]  对既有建筑采用消能建筑加固是近年来结构工程重要研究方向之一，本文针对某公共建筑增设粘滞阻尼器消能减震加固时可能仅实现薄弱楼层增设阻尼器的情况设计模型试验。并对模型的位移响应及自振频率衰减情况进行对比研究。试验结果表明，在薄弱层增设粘滞阻尼器可有效地降低该建筑结构结构的地震反应、延缓结构破坏。

Abstract: The existing building structure with energy dissipation reinforcement is one of the most crucial research directions of structural engineering in recent years. This paper introduces a model test of public building which could only installing viscous dampers at weak layer when taking energy-dissipation method. The paper compares the earthquake displacement response and natural frequency of the with and without damper model. The result indicates that installing the viscous damper on weak layer could effectively decrease seismic response and structure damage.

Key words: weak layer; energy dissipation;  viscous damper; shaking table test
