Dynamic Seismic Mitigation for Tall-Structure Prototypes

Design and construct a vertical structure at least 60cm in height that must withstand a 30-second sustained horizontal oscillation test at a frequency of 2Hz. You must incorporate an integrated, non-powered tuned mass damper (TMD) system to minimize structural deflection at the apex during excitation. Success is measured by the ratio of structural stiffness to the mass of the damping system while maintaining integrity under base-load displacement.
