Earthquake-resistant electronic equipment frame

An electronic equipment frame has two side assemblies each formed of two separate configured corner support channel members rigidly connected by welding by a series of cross struts, and rigidly welded to separate top panel and bottom panel assemblies, with each corner support channel member having a deep, flat-bottomed, V-shaped central channel portion where the angled sidewalls extend to the same depth as the outer end walls of the corner support channel member. The respective ends of each corner support channel member also have extension length portions which permit extended length weld areas for rigidly connecting the respective top and bottom panel assemblies thereto.
