What do structures such as the Eiffel Tower, the Brooklyn Bridge, and the concrete roofs of Pier Luigi Nervi have in common? According to this book, now in its first paperback edition, all are striking examples of structural art, an exciting form distinct from either architecture or machine design. Aided by a number of stunning illustrations, David Billington discusses leading structural engineer-artists, such as John A. Roebling, Gustave Eiffel, Fazlur Khan, and Robert Maillart.
