Abstract
An earthquake resistant frame structure which is shippable in a fully populated condition has a base member, a plurality of support members extending from the base member, a top portion disposed over the ends of the support members, a extension member disposed over the top portion, side stiffeners positioned perpendicularly between the support members, and a tie down assembly system positioned between the base member and a flooring surface. The extension member has a platform section and at least two legs depending substantially perpendicularly therefrom that slidingly engage the support members. The two legs have slots therethrough configured to receive fasteners that, when secured to support members, secure and maintain the extension member in position. First and second panels protrude laterally from the frame structure to form an extension area, from which a bracket hingedly depends. A variety of pin arrangements are used to prevent the removal of the bracket from the hinge. The tie down system includes a floor plate positionable between the frame structure and the flooring surface, a fastener extending through the frame structure, through the floor plate, and into the flooring …
