Abstract: A T-brace for a web member of a steel truss is described. The T-brace includes an elongate base portion, opposing side portions depending from the side edges of the base section, and a first and a second top portion depending from the side portions. The top portions are configured to substantially overlap and to be parallel to the base portion. The side portions of the T-brace are configured to taper from the base portion to the top portions. The T-brace is configured to attach to the central channel portion of the web and be attached by screws penetrating the web and the T-brace. The length of the T-brace is approximately equal to the length of the web. The T-brace is also configured so that when the T-brace is installed in the central channel of a web, and the web is installed in a truss, the T-brace does not extend outside the plane of the truss.
