Mass Shaker on Building

This simulation demonstrates the behaviour of a building subjected to sinusoidal loading. The forcing on the building is caused by the inertia of the vibrating mass stationed on top of the building. .  Notice how the buiding reacts as the frequency of the mass shaker varies.  The magnitude and the frequency at which the mass vibrates could be varied using the scroll bars.  Also, a scrollbar is included to control the building's damping ratio.
