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
