In recent years, isolated systems have been recognized for their effectiveness in protecting structures from earthquake damage. Among the various types of friction isolators, the most advanced is the triple friction pendulum (TFP), which stands out for its hardening response in high-risk scenarios. These isolated systems mitigate earthquake energy by extending the period and enhancing damping. This paper examines the behavior of structures mounted on triple friction pendulums (TFP) under stochastic excitations. The study specifically evaluates the torsional performance of base-isolated buildings using TFP isolators with different damping and effective time periods. The results show that increasing the effective period of the TFP reduces the roof acceleration or Normalized base shear. It also concluded that the collapse risk is reduced with increase in isolator time period. The result demonstrate that the TFP isolator is an effective isolation to reduce torsional response.
