Towards New Structural Forms for Bridges

Structural art: Past, present and future

“…It has been shown that the works of structural art are commonly large-scale structures [9]. Since then, researchers have recognized structural art as a concept, and structural forms are discussed as such in the literature, including: bridge and long-span structures [10][11][12][13][14][15][16][17][18][19][20], thin-shell vaults/roofs [21][22][23], towers [7,24,25], dams [26][27][28][29] and special forms [30]. More recently, studies have evaluated works of structural art by using finite-element numerical tools such that a historical design work can be evaluated with Billington's three criteria of economy, efficiency, and elegance.…”
