The earthquake resistant equipment rack of the present invention includes a base having integrally formed upstanding walls on each end to provide structural rigidity to the connection of the base and a plurality of vertical upright members. The upstanding walls increase the rigidity of the base in conjunction with the vertical members, and also work in conjunction with gussets to further increase the rigidity and stiffness at the base. The gussets are comprised of a vertical wall which is notched on one end to be coupled to a front wall or channel in the base. The gussets also include a top wall and back wall which are directly coupled to the vertical upright members positioned in association with the base. A channel top is coupled between the uppermost portions of the vertical upright members providing the rack with a rectangular frame structure. Channel stiffeners, which consist of relatively short metal members, are coupled to the upper and lower ends of the vertical upright members at the points at which the vertical upright members are coupled to the top and the base. The channel stiffeners transfer lateral stress from the vertical upright members to the base and top of the rack, making the rack's frame stronger and increasing the stiffness in the lateral direction throughout and along the vertical upright members. The base, vertical upright members, top, gussets and stiffening members are all coupled to one another by means of seam welds.
