The many bridges and other work done by Eiffel contributed to the growth of the railway network and had an immense effect on people's lives, but the two projects that really made him famous are the Statue of Liberty and the Eiffel Tower; these were both projects of immense symbolic importance and are internationally recognized landmarks today.
After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, and he made significant contributions in both fields. His interest in these areas was a consequence of the problems he had encountered with the effects of wind forces on the structures he had built.
He was consulted on the defense of the Mississippi River and soon afterward, contracted to construct the City-class ironclads for the United States Navy, and produced seven such ships within five months.
Schlaich was responsible for the Olympic Stadium in Munich. He introduced the "speichenrad" principle to structural engineering and employed it successfully to stadium projects across the globe. He is also the developer of the solar tower (or solar chimney) and is largely credited with inventing the strut and tie model for reinforced concrete.
Rice was the Structural Engineer on three of the most important architectural works of the 20th century: the Sydney Opera House, Pompidou Centre and the Lloyd's Building. He was renowned for his innate ability to act as both engineer and designer. He also worked on the designs of the Louvre Pyramid, the Mound Stand at Lord's Cricket Ground, Kansai International Airport and Stansted Airport.
Khan helped usher in a renaissance in skyscraper construction during the second half of the 20th century, The Council on Tall Buildings and Urban Habitat named their lifetime achievement medal after him.
Although best known for skyscrapers, Khan was also an active designer of other kinds of structures, including the Hajj airport terminal, the McMath–Pierce solar telescope, and several stadium structures
Khan's initial projects were the 43-story DeWitt-Chestnut (1964) and the 35-story Brunswick Building (1965).
Beedle was elected to the National Academy of Engineering in 1972 “for contributions to steel structures research and design practice, especially plastic design and residual stress effects.”
The Council on Tall Buildings and Urban Habitat honored Beedle with creation of the Lynn S. Beedle Achievement Award. He was a recipient of a lifetime achievement award from the American Society of Civil Engineers and received the Franklin Institute’s Frank P. Brown Medal, as well as the John Fritz Medal, the Berkeley Engineering Alumni Society Distinguished Engineering Alumnus Award, and was named Distinguished Professor of Civil Engineering by Lehigh University.
From 1958 to 1974 he taught the design of reinforced concrete and prestressed concrete at Stuttgart University.
Leonhardt was as dedicated throughout his career to research and design, and his major contributions to bridge engineering technology included:
- development of a launching system for prestressed concrete bridges, first used in his 1963 bridge over the Caroní River in Ciudad Guayana, Venezuela
- the 'Hi-Am' anchor for cable stays, in collaboration with the Swiss firm B.B.R.V.
- anchorages in prestressed concrete
- experiments during the 1930s on steel orthotropic decks.
Baker is widely regarded for his work on supertall buildings, but his expertise also extends to a wide variety of structures including the Broadgate-Exchange House, London, and the GM Renaissance Center Entry Pavilion, Detroit. He is also known for his work on long-span roof structures, such as the McCormick Place North Building Expansion, Chicago, the Korean Air Lines Operations Center, Seoul, the Korea World Trade Center Expansion, Seoul, and the Virginia Beach Convention Center
In 2013, Baker received the T.R. Higgins Lectureship Award from the American Institute of Steel Construction. In 2011, he received an honorary doctorate in engineering from the University of Stuttgart and an ASCE Outstanding Projects and Leaders (OPAL) Lifetime Award for Design. In 2010, The Institution of Structural Engineers awarded Baker with their Gold Medal, the Institution's highest accolade. Baker was the first American to be awarded the Fritz Leonhardt Prize For Achievement in Structural Engineering in 2009. In 2008, he received the Fazlur Khan Lifetime Achievement Medal from the Council on Tall Buildings and Urban Habitat.
