This study compares the seismic performance of four types of seismic protection technologies, the triple
pendulum bearings (TPBs), viscous dampers (VDs), tuned mass dampers (TMDs) and high-damping rubber bearings (HDRBs).: Structural models developed in ETABS for 5 and 10-story buildings in Seismic Zone 4 of Peru were used for the analysis. The results demonstrate that TPBs provide the highest reduction of floor accelerations for all the considered buildings and story levels with effectiveness values in the range of 75% to 82%, better than both HDRBs and energy dissipation systems. The study found that HDRBs achieved reduction of 65% to 75% while viscous dampers (VDs) reduced the floor accelerations by 30% to 45%. Tuned mass dampers (TMDs) had the least performance with reductions of 12% to 22%. To summarize, the results indicate that seismic isolation systems, in particular TPBs, provide significantly higher reductions in the floor accelerations than energy dissipation systems.
