Abstract
An electronic equipment rack including a horizontal frame member and a vertical frame member is braced against earthquake damage by means of a metal gusset having a first leg fitting against the horizontal frame member to extend along part of that horizontal frame member, a second leg fitting against the vertical frame member for a first part of that second leg to extend along part of that vertical frame member, a third leg spaced from and extending in parallel to a second part of the second leg, and a fourth leg extending between the second and third legs to abut against another part of the vertical frame member. Solid metal is carried from the vertical frame member to the horizontal frame member by intimately connecting the gusset to the vertical and horizontal frame members.
