ABSTRACT:
A reinforced truss includes a pre-existing top chord and a pre-existing bottom chord, a reinforcing top chord, first and second reinforcing chord heel plates, each of the reinforcing chord heel plates having a plate, a reinforcing truss bracket attached to a first end of the plate, at least one slotted aperture disposed on the plate and spaced to approximately match a pre-existing bolt pattern of the pre-existing truss, and a tie rod bracket. The ends of the reinforcing top chord are captured in the reinforcing truss brackets of the reinforcing chord heel plates. A tie rod is connected to the tie rod brackets of the first and second reinforcing chord heel plates. The slotted aperture allows for the tie rod to be adjusted, thereby adjusting the loading on the reinforcing top chord.
