Abstract

A comfort-based optimal method has been developed for designing floors using tuned inerter mass systems (TIMS) to reduce the vertical-vibration response of floors subjected to human-induced excitations. Acceleration response of the floor and output force of TIMS were first derived via stochastic ana...
