A load-bearing structural member includes an elongate structure body and a strength-reinforcing flat steel strap. The structure body has a top and a bottom, and first and second opposing ends. The steel strap extends along the length of the structure body from one end to the other, and is adapted for transferring an intermediate load acting on the structure body outwardly to the opposing ends of the structure body. Anchor plates located at respective opposing ends of the structure body engage and hold the strap in tension.

1. A load-bearing structural member, comprising: (a) a structure body having a first and second opposing sides, and first and second opposing ends; (b) a strength-reinforcing flat steel strap extending along the length of said structure body from one end to the other, and adapted for transferring an intermediate load acting on said structure body outwardly to the opposing ends of said structure body; and (c) first and second anchors located at opposite ends of said structure body for engaging and anchoring said strap at respective opposite ends of said structure body and holding said strap in tension at the first side of said structure body, each of said anchors comprising first and second complementary anchor plates having a series of mating, spaced-apart, lateral crimps; and (d) means located between the ends of said structure body for engaging and holding said strap adjacent the second side of said structure body, thereby creating an increased supporting reaction force between the ends of said structure body at the location of said means. 2. A structural member according to claim 1, wherein said means comprises a vertical tensioning post centrally located between the ends of said structure body. 3. A structural member according to claim 1, wherein said strap is formed of light-gauge, stress-proof steel having a tensile strength of at least 100,000 psi. 4. A structural member according to claim 1, wherein said structure body is formed of light-gauge steel. 5. A structural member according to claim 1, wherein said structure body has a generally V-shaped or U-shaped cross-section, and comprises a bottom, opposing sides integrally formed with said bottom, and respective flanges integrally formed with said sides. 6. A structural member according to claim 5, wherein each of said flanges includes a longitudinal fastener groove for receiving fasteners. 7. A structural member according to claim 5, and comprising at least one lateral spreader bar located between the sides of said structure body to maintain uniform spacing of the sides from one end of the structure body to the other. 8. A structural member according to claim 1, wherein the depth of the crimps of each anchor plate increases from an inside edge to an outside edge of the anchor plate. 9. A structural member according to claim 8, wherein the width of the crimps is no greater than 80% of the width of the strap. 10. A structural member according to claim 1, wherein said anchor plates are attached to said structure body by a plurality of fasteners extending through the structure body and anchor plates, and adjacent to opposing side edges of strap. 11. A structural member according to claim 1, wherein said anchor plates extend at an angle from the first side of said structure body towards the second side of said structure body to define a sloping bed for holding said strap. 12. A structural member according to claim 1, wherein said structure body comprises a steel C-channel including a vertical web member and spaced-apart top and bottom flange members integrally formed with said web member. 13. A structural member according to claim 12, and comprising top and bottom support panels attached to respective top and bottom flange members of said C-channel. 14. A structural member according to claim 13, wherein said flange members include respective integrally-formed hooks adapted for mating with complementary hooks formed with respective top and bottom support panels for connecting said support panels and said structure body together.
