Abstract:
1. A method of protecting a building structure against dynamic forces from accelerations of a base of the building structure, comprising: supporting the building structure with a load bearing system including a stable supporting element able to swing in any lateral direction and lift the building structure and an unstable supporting element able to swing in any lateral direction and lower the building structure, the stable supporting element and the unstable supporting element being connected to the base at base-connected support points; and displacing the base-connected support points relative an inert mass of the building structure during the accelerations of the base to cause a minimal lift of the building structure generating a small stabilizing returning force which returns the building structure to an original position at an insignificant acceleration of the building structure with a long period of a natural oscillation of the building structure.
