Abstract: In order to improve the energy dissipation capacity of the irregular steel joints of pseudo-classic architecture， the replace‑
able viscous damping device was set up at the location of decorated bracket to dissipate seismic energy. Six specimens of pseudo-
classic architecture joints were designed and manufactured， including the single beam-column joint （SBJ） series and double beam-
column joint （DBJ） series. The hysteretic curves and skeleton curves of the specimen and the viscous damper were obtained by the
sine wave dynamic loading with displacement and frequency control， and the deformation and energy dissipation capacity of the
specimen and the viscous damper were analyzed， respectively. The results indicate that the improved dynamic loading system has
achieved good test results， and the failure mode of the irregular steel joint of pseudo-classic architecture is improved by installing a
viscous damper at the decorated bracket position. The viscous damper has good working state after buckling in the plastic hinge
area of the beam end of the specimen， and the hysteresis ring of the specimen becomes full gradually. The larger the damping coeffi‑
cient of the damper， the fuller the hysteresis rings of the node and the stronger the energy dissipation capacity. With the increase of
damping coefficient， the bearing capacity of specimens with controlled joints is increased by 18%~46% compared with that of
without controlled， and the viscous damper increases the bearing capacity of specimens with double beam-column joints more sig‑
nificantly. The displacement ductility coefficient of the specimen is between 1.77 and 2.05， and the ductility of the specimen is
slightly improved after the viscous damper is installed. The strength degradation coefficients are all about 1.0.
