Roger, Perhaps the best reference on the topic is the Uniform Building Code, available in most libraries. Another source is "seismic bracing" on the Internet. However, there are many "common sense" precautions that can be taken, among them:
1. Mount heavy and/or dense objects (power supplies and batteries) at the lowest point in a rack, or on the floor. 2. Bolt all racks and cabinets to the concrete floor with heavy-duty (1/2 inch or larger) anchor bolts. 3. Brace the tops of racks and cabinets to the ceiling, or cross-brace them from wall to wall with steel strut. 4. Brace air conditioners, shelves, and any appliance or fixture against the wall with heavy-duty anchors. 5. Equip all storage lockers and cabinets with substantial latches on the doors. 6. Don't leave any test equipment sitting on a bench or table, where it can slide off. If your equipment shack is not made of reinforced concrete, you might need to add reinforcing plates on the outside wall to keep the anchors from pulling through the wall. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Roger Stacey Sent: Tuesday, May 27, 2008 9:22 PM To: Repeater-Builder Subject: [Repeater-Builder] Earthquake Resistant Hi all, Our group wants to upgrade our repeater site to be more earthquake resistant. We realize that there are no "earthquake proof" repeaters but we want to improve any chances of survivability. Any ideas or suggestions would be greatly appreciated. Thanks Roger VA7RS
