🏗️ Shake Table Lab: Building Resonance, Damping and Base Isolation

A 1:25 laboratory shake table carries a stiff low-rise, a tall flexible frame and a tall frame on base isolators or with a tuned mass damper, each solved as a multi-storey shear building with modal damping and Newmark integration. Compare resonance, response spectra and inter-storey drift for synthetic earthquake records, pulses and sine sweeps, and check the resonance curve against exact transmissibility.
