The article focuses on the arch, and shows how to modify 'simple' forms to produce dramatic forms with a distinct engineering influence. In the old days, the arch was a form that united engineering and architecture, and designers and builders were known as architects and were also engineers. Modern science and engineering, helped by the proper use of new materials and new analytical tools, today allow the form and use of the arch to be greatly expanded. The article presents, as evidence of this, some examples of arch design and construction, that were engineered by the author and his colleagues. It is first shown how different architectural and structural shapes can be obtained by locating arch ties along the bottom, mid-height, or top deck of the bridge. Turning a whole arch plane away from its vertical position to lie on a horizontal plane changes an arch into an arc; several examples of this are shown. Finally, two examples are shown of extending the arch into the third dimension, so that the arch axis is curved in both horizontal and vertical projections; they are both for large stadia, whose architectural layout demanded such shapes. These examples show clearly that the arch is a unique and versatile structural form for expressing force flow and aesthetic appearance.
