Neural surrogates for structural dynamic response no longer fit the whole frequency-response curve directly; they first predict frequency-independent modal quantities and then reconstruct the response by analytical modal superposition. Across 20,000 designs each for a steel truss tower and a tapered beam, with supplied modal frequencies, 5% reference damping and a declared band, the modal configurations give mean displacement-history errors of 0.73–0.76% and 0.029–0.116% respectively. These figures cover fixed topology and conditional inference, and do not yet establish design-only deployment or an earthquake-engineering assessment.
