Probabilistic Robust Optimization Method for Variation of Phase Characteristics of Earthquake Motions With Multiple Impulse Inputs

Year: 2024

Type: article

Abstract: In this paper, a new method is proposed that replaces the ground motion with multiple impulses in a rational method by considering the repetition characteristics of the ground motion, and a method to set the input level of impulse ground motion in consideration of robustness. In addition, for an example problem of optimizing the placement of inter-story dampers in a multi-mass point system model, it is shown that the use of impulse ground motions provides a design solution that is more robust against variations in the phase characteristics of ground motions than optimization that uses only specific ground motions.
