Due to the process adjustment and fortification category improvement,a frame structure of Sinvoac adopts the shock-absorption reinforcement method with the addition of viscous dampers.In this paper,the elastoplastic analysis of rare earthquakes is carried out by constructing an elastoplastic model.The results show that after adding dampers for shock-absorbing reinforcement of the structure,the key indicators such as structural apex displacement,interstory displacement angle,and base shear force all meet the requirements of rare earthquakes;the seismic energy is mainly dissipated by dampers and frame beams,and frame columns are basically not involved in energy consumption;after shock-absorption reinforcement,the frame beams meet the performance level requirements,and the frame column meets the performance level requirements after reinforced by the outer steel.
