Abstract

A method of tensioning concrete is disclosed.

Claims

1. A composite structure, comprising:

a plurality of cables;

a concrete member cured about the cables, wherein the plurality of cables are tensioned within the concrete member for inducing a strength to the concrete member;

at least one sensing component on a cable of the plurality of cables, wherein the sensing component is configured to;

(a) sense at least one condition in the concrete member when the concrete member is cured, and (b) wirelessly activate for obtaining a measurement of the condition in the concrete member; and

a tension load distribution member attached or connected to at least one of the cables to distribute a tension on the at least one cable over a greater area of an interior of the concrete member than the at least one cable would provide without the tension load distribution member;

wherein the concrete member is poured about the tension load distribution member for embedding the tension load distribution member in the concrete member such that for each portion of the at least one cable, which contacts the tension load distribution member, the portion is entirely surrounded by concrete of the concrete member.

2. The composite structure of claim 1, wherein the sensing component and the tension load distribution member are on a same one of the cables.

3. The composite structure of claim 1, wherein the at least one cable is threaded through an eye of the tension load distribution member.

4. The composite structure of claim 1, wherein the tension load distribution member includes at least one projection for distributing the tension over the greater area of the interior of the concrete member.

5. The composite structure of claim 4, wherein the at least one projection is oriented parallel to a load support surface of the concrete member.

6. The composite structure of claim 4, wherein a cross section of the at least one projection is one of cylindrical, paddle, elliptical, or rectangular shaped.

7. The composite structure of claim 1, wherein power to activate the sensing component is obtained by a passive radio technique.

8. The composite structure of claim 1, wherein the condition includes a reduction of the tension on the cable and wherein the at least one sensing component includes a sensing component able to detect the reduction of the tension on the cable.

9. The composite structure of claim 1, wherein the plurality of cables comprises two sets of cables, wherein the two sets of cables run substantially perpendicular to each other, and wherein, for each set of cables, the cables of the set run substantially parallel to other cables of the respective set of cables.

10. The composite structure of claim 9, wherein when viewed from at least one position, the cables are substantially straight, and wherein, two cables, one each from the two sets of cables, are spaced apart at a crossing of the two cables.

11. The composite structure of claim 9, wherein at least one set of the cables of the two sets of cables is diagonally positioned across a length of the composite structure.

12. The composite structure of claim 9, wherein at least one set of cables of the two sets of cables is positioned substantially parallel to a load support surface of the concrete member.

13. The composite structure of claim 1, wherein the measurement is transmitted wirelessly by the sensing component.

14. The composite structure of claim 1, wherein the condition includes moisture in the concrete member.

15. The composite structure of claim 1, wherein the load distribution member includes extents away of the at least one cable for at least a diameter of the at least one cable.

16. The composite structure of claim 1, wherein the load distribution member increases a resistance of a force on the concrete member transverse to a length of the at least one cable.

17. A composite structure, comprising:

a plurality of cables;

a concrete member cured about the cables, wherein the plurality of cables are tensioned;

at least one sensing component on a cable of the plurality of cables, wherein the sensing component is fully surrounded by concrete of the concrete member, wherein the sensing component is configured to;

(a) sense moisture in the concrete member when the concrete member is cured and (b) wirelessly activate for obtaining a measurement of the moisture in the concrete member, wherein power to activate the sensing component is obtained by a passive radio technique, and wherein the measurement is transmitted wirelessly by the sensing component; and

a tension load distribution member attached or connected to at least one of the cables to distribute a tension on the at least one cable over a greater area of an interior of the concrete member than the at least one cable would provide without the tension load distribution member;

wherein the concrete member is poured about the tension load distribution member for embedding the tension load distribution member in the concrete member such that for each portion of the at least one cable, which contacts the tension load distribution member, the portion is entirely surrounded by concrete of the concrete member.

18. The composite structure of claim 17, wherein the sensing component and the tension load distribution member are on a same one of the cables.

19. The composite structure of claim 17, wherein the at least one cable is threaded through an eye of the tension load distribution member.

20. The composite structure of claim 17, wherein the tension load distribution member includes at least one projection for distributing the tension over the greater area of the interior of the concrete member.
