Abstract

A reinforced stud-framed wall, including a bottom plate; first and second vertical studs; a member supported on the bottom plate, the member having a compression strength greater than a compression strength of the bottom plate; the first vertical stud having a bottom end supported on the member with a first contact area, whereby a load on the first contact area is spread over a first area on the bottom plate larger than the first contact area; and the second vertical stud having a bottom end supported on the member with a second contact area, whereby a load on the second contact area is spread over a second area on the bottom plate larger than the second contact area.

First claim

I claim:

1. A reinforced stud-framed wall, comprising:
a) a bottom plate;
b) an outermost vertical stud in the stud-framed wall;
c) a member supported on the bottom plate, the member having a compression strength greater than a compression strength of the bottom plate; and
d) the outermost vertical stud having a bottom end supported on the member with a first contact area, whereby a load on the first contact area is spread over a first area on the bottom plate larger than the first contact area.

2. The reinforced stud-framed wall as in claim 1 , wherein the member includes an engineered lumber.

3. The reinforced stud-framed wall as in claim 1 , wherein the member includes a solid metal plate.

4. The reinforced stud-framed wall as in claim 1 , wherein the member includes a hollow metal plate.

5. The reinforced stud-framed wall as in claim 1 , wherein the outermost vertical stud is a post.

6. The reinforced stud-framed wall as in claim 1 , and further comprising:
a) a second vertical stud; and
b) a bottom end of the second vertical stud is supported on the member.

7. The reinforced stud-framed wall as in claim 1 , and further comprising:
a) a tie rod anchored to a foundation;
b) a bearing plate on top of the member, the bearing plate having a second contact area on the member;
c) the tie rod extending through the member and the bearing plate;
d) a fastener tightened against the bearing plate to exert tension on the tie rod; and
e) the bearing plate transfers a load onto the bottom plate over a second area larger than the second contact area.

8. The reinforced stud-framed wall as in claim 7 , wherein the bearing plate is sized so that the load per unit area on the second area is less than or equal to the compression strength per unit area of the bottom plate.

9. The reinforced stud-framed wall as in claim 7 , wherein the fastener includes a nut.

10. The reinforced stud-framed wall as in claim 7 , wherein the fastener is axially expandable.

11. The reinforced stud-framed wall as in claim 7 , wherein:
a) the member includes hollow metal; and
b) the fastener is axially expandable.

12. The reinforced stud-framed wall as in claim 7 , wherein:
a) the member includes an engineered lumber; and
b) the fastener is axially expandable.

13. The reinforced stud-framed wall as in claim 1 , and further comprising:
a) a tie rod anchored to a foundation; and
b) the tie rod extends through the member.

14. The reinforced stud-framed wall as in claim 13 , wherein the member includes engineered lumber.

15. The reinforced stud-framed wall as in claim 13 , wherein the member includes solid metal.

16. The reinforced stud-framed wall as in claim 13 , wherein the member includes hollow metal.

17. A reinforced stud-framed wall, comprising:
a) a bottom plate extending from one end of the stud-framed wall across a plurality of stud bays;
b) a double top plate comprising a first member and a second member on top of the first member, the first member has a compression strength greater than a compression strength of the second member;
c) the bottom plate has a compression strength greater than a compression strength of the second member; and
d) a vertical stud disposed between the bottom plate and the top plate.

18. The reinforced stud-framed wall as in claim 17 , wherein the bottom plate includes an engineered lumber.

19. The reinforced stud-framed wall as in claim 17 , wherein the bottom plate includes hollow metal.

20. The reinforced stud-framed wall as in claim 17 , wherein the bottom plate includes solid metal.

21. The reinforced stud-framed wall as in claim 17 , wherein the first member includes hollow metal.

22. The reinforced stud-framed wall as in claim 17 , wherein the first member includes an engineered lumber.

23. The reinforced stud-framed wall as in claim 17 , wherein the first member includes solid metal.

24. The reinforced stud-framed wall as in claim 17 , and further comprising a tie rod anchored to a foundation and extending through the bottom plate and the double top plate.

25. A reinforced stud-framed wall, comprising:
a) a bottom plate;
b) a top plate;
c) a first member supported on the bottom plate;
d) a second member disposed below and engaging the top plate;
e) an outermost vertical stud in the stud-framed wall disposed between the first member and the second member, the outermost vertical stud including a bottom end portion supported by the first member and a top end portion supporting the second member;
f) the first member having a compression strength greater than a compression strength of the bottom plate; and
g) the second member having a compression strength greater than a compression strength of the top plate.

26. The reinforced stud-framed wall as in claim 25 , wherein the first and second members include engineered lumbers, plastic, glass filled plastic or fiberglass.

27. The reinforced stud-framed wall as in claim 25 , wherein the first and second members include hollow metal.

28. The reinforced stud-framed wall as in claim 25 , wherein the first and second members include solid metal.

29. The reinforced stud-framed wall as in claim 25 , and further comprising a reinforcement stud attached to the outermost vertical stud, the first reinforcement stud having a bottom end supported by the first member and a top end supporting the second member.

30. The reinforced stud-framed wall as in claim 25 , and further comprising:
a) a tie rod anchored to a foundation;
b) a first bearing plate on top of the first member, the bearing plate having a first contact area on the first member;
c) the tie rod extending through the first member and the first bearing plate;
d) a fastener tightened against the first bearing plate to exert tension on the tie rod; and
e) the first bearing plate transferring a load onto the bottom plate over a second area larger than the first contact area.

31. The reinforced stud-framed wall as in claim 25 , wherein:
a) a second vertical stud is disposed between the first member and the second member; and
b) a bottom end of the second vertical stud is supported on the first member and a top end of the second vertical stud supporting the second member.
