Based on the characteristics of series compensation platform structure, a method of installing modified Pall-typed friction dampers for seismic passive control was proposed. Compared with the conventional, the modified Pall-typed friction damper has the same effect on energy dissipation, and it is superior in imposing pretension at both ends and saving friction materials. The equations of relation between brace displacement and internal force of the modified Pall-typed friction damper were derived. Besides, the time-history analysis method for seismic responses of series compensation platform structures with modified Pall-typed friction dampers was established, and a sine amplitude-modulation wave train was applied to analyzing the dynamic responses of these structures. The results show that, the displacement of the series compensation platform structures with modified Pall-typed friction dampers decrease to some extent. The seismic control is effective.
