In the analysis of PMSCS the equations of motion of the seismically excited system are developed. The seismic response control effectiveness of the proposed PMSCS under stationary and nonstationary random processes was evaluated by comparing its seismic response with the response of its conventional (uncontrolled) mega-sub structure counterpart. A parametric study of the relative stiffness between the mega-frame and substructure of the PMSCS is presented and discussed. The region over which these structural characteristics yield the optimum seismic response control of the PMSCS is identified and serves as a very useful design tool for practitioners. The results show that the proposed PMSCS offers an effective means of controlling the seismic displacement and acceleration response of tall/super-tall mega-systems.
