Abstract

The invention relates to a combination of a foundation anchor and energy damper for vertical tanks or similar containers for liquids with a thin wall and continuous support, comprising an energy dissipation component centrally connected to a foundation anchor component by means of a linking component, the energy dissipation component comprising one or more superimposed and horizontally arranged energy dissipating plates with a rhombic shape truncated at the vertices thereof, wherein the shorter diagonal is normal to the wall of the tank and the side ends or vertices corresponding to the longer diagonal have quadrangular extensions for support on a load transmission component that is connected to the wall of the tank so as to transmit and distribute the forces developed by the one or more energy dissipating plates. Alternatively, the energy dissipating plates are trapezoidal with the longer parallel side tangential to the wall of the tank.

First claim

The invention claimed is:

1. A combination of foundation anchor and energy damper for a thin-walled and continuous support structure supported on foundations, wherein the combination comprises:
a foundation anchor component;
an energy dissipation component;
a linking component; and
a load transmission component;
wherein the energy dissipation component is centrally attached to the foundation anchor component by the linking component and wherein the energy dissipation component is constituted by one or more superimposed and horizontally arranged energy dissipating plates having a rhombus shape as formed by two diagonals, a shorter one and a longer one, connecting pairs of opposite vertices, and two pairs of parallel sides, the rhombus shape being truncated at its vertices and the vertices corresponding to the longer diagonal defining lateral ends of the energy dissipating plates, wherein the one or more energy dissipating plates are disposed in a manner such that the shorter diagonal of the rhombus shape is normal to the thin-wall and wherein the lateral ends have quadrangular extensions for support on the load transmission component, which is attached to the thin-wall so as to transmit and distribute forces developed by the energy dissipating plate or plates to the thin-wall.

2. The combination of foundation anchor and energy damper according to claim 1 , wherein the linking component comprises two tightening plates, one on each side of the energy dissipation component, and respective washers, a nut and a lock nut, wherein the tightening plates and the energy dissipating plate or plates have a common central through-hole for receiving therethrough an anchor bolt of the foundation anchor component and for attaching the energy dissipation component to the foundation anchor component by means of tightening the nut and lock nut against the tightening plates and washers.

3. The combination of foundation anchor and energy damper according to claim 2 , wherein the anchor bolt of the foundation anchor component is a conventional metal anchor bolt embedded in the foundations.

4. The combination of foundation anchor and energy damper according to claim 2 , wherein the anchor bolt of the foundation anchor component is perforated and adhered to the foundation by means of an epoxy resin.

5. The combination of foundation anchor and energy damper according to claim 1 , wherein the foundation anchor component comprises an anchor bolt with one end on the foundations and an opposite, free end for attachment of the energy dissipation component, wherein the linking component comprises two tightening plates, one on each side of the energy dissipation component, respective washers, a lock nut and a metal coupling with an end screwed to the free end of the anchor bolt of the foundation anchor component, wherein the tightening plates and the energy dissipating plate or plates have a common central through hole for receiving therethrough a removable fastening bolt that is inserted in an opposite end of the metal coupling to attach the energy dissipation component to the foundation anchor component by means of tightening the lock nut and the removable fastening bolt against the tightening plates and washers.

6. The combination of foundation anchor and energy damper according to claim 5 , wherein the anchor bolt of the foundation anchor component is a conventional metal anchor bolt embedded in the foundations.

7. The combination of foundation anchor and energy damper according to claim 5 , wherein the anchor bolt of the foundation anchor component is perforated and adhered to the foundation by means of an epoxy resin.

8. The combination of foundation anchor and energy damper according to claim 1 , wherein the energy dissipation component comprises two or more energy dissipating plates and the linking component incorporates separating plates between the energy dissipating plates so that the latter deform without interfering with each other in an earthquake.

9. The combination of foundation anchor and energy damper according to claim 1 , wherein the load transmitting component comprises: a group of horizontal sag plates that serve as a support means for the lateral ends of the energy dissipating plate or plates; and a reinforcement plate of the thin-wall to which the group of horizontal sag plates is attached.

10. The combination of foundation anchor and energy damper according to claim 9 , wherein the energy dissipating plate or plates are provided at their lateral ends with cylindrical bars, which are slidable along the horizontal sag plates of the load transmission component.

11. A combination of foundation anchor and energy damper for a thin-walled and continuous support structure supported on foundations, wherein the combination comprises:
a foundation anchor component;
an energy dissipation component;
a linking component; and
a load transmission component;
wherein the energy dissipation component is centrally attached to the foundation anchor component by the linking component and wherein the energy dissipation component is constituted by one or more superimposed and horizontally arranged energy dissipating plates having a trapezoidal shape as formed by two parallel sides, a shorter one and a longer one, two other sides that are not parallel and four vertices where the parallel sides meet the non-parallel sides, the vertices of the longer parallel side with the non-parallel sides defining lateral ends of the energy dissipating plates, wherein the one or more energy dissipating plates are disposed in a manner such that the longer parallel side of the trapezoidal shape is tangent to the thin-wall, wherein the lateral ends have quadrangular extensions for support on the load transmission component, which is attached to the thin-wall so as to transmit and distribute forces developed by the energy dissipating plate or plates to the thin-wall.

12. The combination of foundation anchor and energy damper according to claim 11 , wherein the linking component comprises two tightening plates, one on each side of the energy dissipation component, and respective washers, a nut and a lock nut, wherein the tightening plates and the energy dissipating plate or plates have a common central through-hole for receiving therethrough an anchor bolt of the foundation anchor component and for attaching the energy dissipation component to the foundation anchor component by means of tightening the nut and lock nut against the tightening plates and washers.

13. The combination of foundation anchor and energy damper according to claim 12 , wherein the anchor bolt of the foundation anchor component is a conventional metal anchor bolt embedded in the foundations.

14. The combination of foundation anchor and energy damper according to claim 12 , wherein the anchor bolt of the foundation anchor component is perforated and adhered to the foundation by means of an epoxy resin.

15. The combination of foundation anchor and energy damper according to claim 11 , wherein the foundation anchor component comprises an anchor bolt with one end on the foundations and an opposite, free end for attachment of the energy dissipation component, wherein the linking component comprises two tightening plates, one on each side of the energy dissipation component, respective washers, a lock nut and a metal coupling with an end screwed to the free end of the anchor bolt of the foundation anchor component, wherein the tightening plates and the energy dissipating plate or plates have a common central through hole for receiving therethrough a removable fastening bolt that is inserted in an opposite end of
