ABSTRACT:
A seismic protection system for a structure includes a foundation plate with retaining walls for supporting and isolating the structure from the ground, and oscillatory, vibratory and hydro-pneumatic arrangements for movably coupling the structure to the foundation plate and retaining walls. The oscillatory arrangement permits horizontal movement between the structure and foundation plate and contains fluid. The vibratory arrangement is coupled to the oscillatory arrangement for relative vertical movement of the structure and for dampening and transferring loads on the structure to the oscillatory arrangement. The hydro-pneumatic arrangement has a surge chamber, and permits and controls movement between the structure and the retaining walls. A wind driven pressure generator mounted on the structure is coupled to the oscillatory, vibratory and hydro-pneumatic arrangements to coordinate their action in response to wind driven structure movements.
