Aseismatic system for constructions such as buildings, dry bridges, tanks and like
First Claim
1. As aseismatic system for supported structures such as buildings, dry bridges and tanks carried by supporting structures such as foundations and piers, characterized in that said system comprisesabutment/decoupling means for disposition between a supported structure and a supporting structure for operatively and supportively coupling the supported structuring on the supporting structure, and being responsive to a seismic event for decoupling the supported structure from the supporting structure, andreturn means including rope means connecting said return means to said abutment/decoupling means for resisting relative displacements between the supported structure and the supporting structure upon decoupling of the supported structure from the supporting structure at said abutment/decoupling means with a force of constant value independent of said relative displacement.

Abstract
An aseismatic system for constructions such as buildings, bridges, tanks and like comprising abutment/decoupling means for the deck structure from the piers or for the building from its foundation as well as return means for resisting any relative displacements between the deck structure and the piers or between the building and its foundation, which is based upon the principle to prevent the bridge or the building to be subjected to the seismic effects caused by the deck structure mass by decoupling the construction on the horizontal plane by means of said multi-directional movable abutment means, with nearly null resistance to sliding movements and by means of a connection between the deck structure and its abutment members based upon a swinging device adapt to exert a predetermined action of constant value.

1. As aseismatic system for supported structures such as buildings, dry bridges and tanks carried by supporting structures such as foundations and piers, characterized in that said system comprises
abutment/decoupling means for disposition between a supported structure and a supporting structure for operatively and supportively coupling the supported structuring on the supporting structure, and being responsive to a seismic event for decoupling the supported structure from the supporting structure, and return means including rope means connecting said return means to said abutment/decoupling means for resisting relative displacements between the supported structure and the supporting structure upon decoupling of the supported structure from the supporting structure at said abutment/decoupling means with a force of constant value independent of said relative displacement.
- 11. An aseismatic system according to claim wherein said counterweight means, said pulley means and said resilient spring means have guides to prevent transverse movement with respect to the supporting structures.
