ABSTRACT:
A support to provide earthquake resistance for structures, such as a mobile home, which have a long metal bottom beam on the underside of the structure, can be provided by a system of long wooden cross beams at about right angles to the bottom beams, where the cross beams rest on at least two units of cribbing. The cribbing can itself rest on a bottom platform, a pad, or the ground. A bottom platform can function as a shim or leveling device. The cribbing can consist of two or more layers of elongated blocks, such as rough cut 6".times.8" or 8".times.8" wooden timbers. The cribbing units can be attached to themselves and to the main beam by metal anchors and ties, and the main beam can be attached to the bottom beam of the supported structure by metal clamps.
