Earthquake-resistant electronic equipment frame

A frame apparatus for supporting electronic equipment against excessive vibration, comprising in combination,

• two respective side assemblies rigidly connected by a top panel assembly and a bottom panel assembly;
• each said side assembly including at least two corrugated side channel members rigidly connected to one another by a plurality of cross strut members, each said corrugated side channel member having a configured profile comprising a flat-bottomed V-shaped central portion with substantially flat extension walls extending therefrom which walls respectively terminate in end flange members, said end flange members being of substantially equal length, one of said end flange members having a return lip portion, the other one of said end flange members being lipless and formed with a plurality of notches, and each said notch sized to accommodate insertion of a respective said cross strut member;
• each said cross strut member formed of a channel profile and terminating at each outer end in a bent tang extension end, each said bent tang extension end rigidly affixed via an offset joint with a fillet weld to said return lip portion of the associated said corrugated side channel member;
• two spaced apart top panel stiffener members rigidly affixed to said top panel assembly and having a profile complimentary to said profile of said central portion of said corrugated side channel members and rigidly affixed thereto;
• a plurality of L-shaped bent tube stiffener members, with a first series of said bent tube members rigidly affixed to both said top panel assembly and said respective side assemblies, and a second series of said bent tube stiffener members rigidly affixed to both said bottom panel assembly and said respective side assemblies;
• at least one access opening formed in said top panel assembly to permit access therethrough;
• and a top panel stiffener channel rigidly affixed to said top panel assembly adjacent said access opening for supporting said top panel assembly adjacent said access opening.
