Abstract
Cost-effective reinforcement system for frames walls helps support against failure from violent lateral forces. Strips of resin-impregnated textile in crossed pairs are attached to frame members. Attachment of ends of strips is ductile due to use of multiple fiber anchors.

A system for reinforcing a framed structure, the structure including:
- framing members including:
- at least one pair of vertical support members in parallel spaced-apart relation, one horizontal top connecting member connecting the top portions of the vertical support members, and at least one horizontal bottom connecting member connecting the bottom portions of the vertical support members;
- said system including:
- a pair of strips of resin-impregnated textile, each strip adapted to reach diagonally from a junction of a top connecting member with a support member to a junction of a bottom connecting member with a different support member;
- each of said pair of strips including:
- a first end attached to the junction of a top connecting member with a vertical support member;
- a second end attached to the junction of a bottom connecting member with a vertical support member;
- an inner face disposed toward the framing members of the structure;
- an exposed face disposed away from the framing members of the structure;
- and
- a middle portion between said first and second ends;
- and
- ductile attachment means attaching each of said four ends to each said junction of a connecting member with a support member.
A method for reinforcing a framed structure that includes framing members, including a first vertical support member and a second vertical support member in parallel spaced-apart relation, one horizontal top connecting member connecting the top portions of the vertical support members, and at least one horizontal bottom connecting member connecting the bottom portions of the vertical support members;
- the method including the steps of:
- affixing a first anchor plate to the junction of the first support member with the top connecting member;
- affixing a second anchor plate to the junction of the second support member with the top connecting member;
- affixing a third anchor plate to the junction of the first support member with the bottom connecting member;
- affixing a fourth anchor plate to the junction of the second support member with the bottom connecting member;
- providing a first strip of material having:
- a first end, a second end, and a middle portion therebetween and with a length approximating the distance between the first and fourth anchor plates;
- attaching the first end of the first strip to the first anchor plate using ductile attachment means;
- attaching the second end of the first strip to the fourth anchor plate using ductile attachment means;
- providing a second strip of material having:
- a first end, a second end, and a middle portion therebetween and with a length approximating the distance between the second and third anchor plates;
- attaching the first end of the second strip to the second anchor plate using ductile attachment means;
- and
- attaching the second end of the second strip to the third anchor plate using ductile attachment means.

- providing a second strip of material having:
- a first end, a second end, and a middle portion therebetween and with a length approximating the distance between the junction of the second support member with the top connecting member and the junction of the first support member with the top connecting member;
- attaching the first end of the second strip to the junction of the second support member with the top connecting member using ductile attachment means;
- and
- attaching the second end of the second strip to the junction of the first support member with the bottom connecting member using ductile attachment means such that the middle portion of the second strip overlies the middle portion of the first strip.
