Key Points

To establish a deep operator network framework capable of predicting the steady-state frequency response of linear dynamical systems exposed to harmonic excitations.
Formulated an operator learning algorithm using Deep Operator Networks (DeepONet) to map dynamic inputs directly to structural frequency response functions.
Evaluated the algorithmic framework on simulated linear dynamical structural systems subjected to varied harmonic load profiles.
The deep operator network effectively predicts steady-state frequency responses across continuous frequency domains in linear dynamical systems.
The approach provides rapid surrogate modeling for structural dynamics, avoiding repeated numerical integration of equations of motion.
