Abstract：For the cam response amplification viscous damper (CRAD-VD), CRAD-VD energy dissipation unit is developed based on ABAQUS software, and explicit solution programs for nonlinear analysis of corresponding energy dissipation system are compiled The ABAQUS calculation results of single-degree-of-freedom damping system are compared with the analysis results of MATLAB program, and the accuracy of CRAD-VD energy dissipation unit and solution program is verified Then, the seismic performance analysis of three-dimensional nonlinear model of fabricated energy dissipation system is carried out. The results show that the developed CRAD-VD energy dissipation unit and solving program can accurately calculate the three-dimensional structural model; Three-dimensional structure system with small tonnage viscous dampers in series can get similar or better response control effect of directly installed tonnage dampers, effectively reduce the damage degree of assembled frame beams and columns, and reflect the response amplification effect of CRAD; The displacement amplitude of the series damper is always equal to the preset eccentricity, which can avoid the failure of the damper due to the displacement exceeding the limit under extremely rare earthquake.
