ABSTRACT:
A force-resisting structure, such as a press frame, is composed of a plurality of substantially planar loops each made from a single piece of metal plate. The loops are connected together in spaced, parallel relation by bolts which perform essentially no force-resisting function. The structure contains no welds. All components requiring machining are machined before assembly, and there are no machining operations thereafter.
