ABSTRACT
Structural form is always an important consideration in determining how stresses are resisted and transmitted, but under certain conditions, the structure’s form can be ideally matched with the statical form of resistance. Form-resistant structures transmit their loads in parallel with the material axially by matching form to forces. Matching form to forces is theoretically predictable but this inherent efficiency comes with risks. Overall, the structural advantages of form-resistant structures are desirable, particularly their predictable structural behavior. The pervasive half-circle Roman arches aren’t structurally accurate reflections of a proper compressive shape, but their regular radii made them easy to repeatedly form and build, particularly with remedial tools. Linking form and forces is fundamental to understanding structural behavior. Contemporary digital modeling programs have returned to graphic statics for quickly analyzing form and forces under changing conditions. Frequently form-resistant elements are used in long span, single volume buildings or infrastructural projects that require the elevated levels of efficiency and performance.
