Analysis of damping performance of the frame structure with high-efficiency energy dissipation viscoelastic dampers
A high-efficiency energy dissipation viscoelastic damper(HEVD)is proposed,and the seismic performance of a frame structure with a HEVD is studied.Firstly,the construction of the viscoelastic damper with high efficiency energy dissipation is presented,the formulas for calculating the damping magnification factor under small,large and giant earthquakes are derived,and the variation law of the magnification factor is analyzed.In addition,the equivalent damping ratio of the frame structure with the HEVD is derived.The analysis shows that the difference of the time-history curve of the top displacement of the frame structure before and after the damping equivalence is not more than 10％.
