Analysis of prefabricated concrete beam column joint with sector lead viscoelastic damper（SLVD）is carried out and validated by comparing with experimental results.Comparison of seismic performance of joint between energy-dissipation and ordinary joint is conducted.Then analysis results in different design parameter cases are carried out for energy-dissipative specimen under different design parameters.It is shown that compared with ordinary prefabricated joint

the component joint with SLVD improves the initial stiffness and bearing capacity and enhances the energy-dissipation capacity of specimen in a certain degree.With the increase of axial compression ratio

stress of concrete decreases obviously.Seismic performance of specimen improves with the increasing lead diameter

rubber hardness and sector radius

when the sector radius of damper is over a certain value

seismic performance of specimen degrades.
