What type of bridge is the bridge over the Arve by Robert Maillart?
arch concrete bridge
Engineering Timelines – Arve Bridge, Vessy. Towards the end of his career, Swiss engineer Robert Maillart developed further the three-hinge arch concrete bridge system he had been using, for a road bridge over the River Arve in south east Geneva. It features a pointed arch and unusual X-shaped cross walls.
Why did maillart move to the broken arch design for the Felsegg Vessy Lachen and Garstatt bridges?
Maillart did not agree. Why did Maillart move to the “broken arch” design for the Felsegg, Vessy, Lachen, and Garstatt bridges? It more accurately represented the moment diagram. On the bridges he designed near the end of his life, Maillart began changing the shape of the cross walls on his arch bridges.
Where is the Salginatobel bridge?
Schiers
Salginatobel Bridge/Location
The Salginatobel Bridge, near Schiers, Graubünden canton, Switzerland. Designed by Robert Maillart, the hollow-box reinforced concrete arch, with a span of 90 metres (295 feet), was built in 1930.

Who is the best bridge maker?
Ralph Modjeski
- Modjeski was world-famous as a designer of bridges and rail lines.
- Modjeski was considered “America’s greatest bridge builder.” He was the recipient of numerous awards and honorary degrees.
- He died June 26, 1940, in Los Angeles, California.
What types of bridges were built using the truss design?
Trusses are popular for bridge building because they use a relatively small amount of material for the amount of weight they can support. They commonly are used in covered bridges, railroad bridges, and military bridges.
What is the ratio of RCC?
What is RCC? Why TMT Bar is required in RCC?
| Concrete Grade | Proportion of Cement : Sand : Stone pieces | Expected Compressive Strength at 28 days |
|---|---|---|
| M10 | 1 : 3 : 6 | 10 N/mm2 or 100 Kg/cm2 |
| M15 | 1 : 2 : 4 | 15 N/mm2 or 150 Kg/cm2 |
| M20 | 1 : 1.5 : 3 | 20 N/mm2 or 200 Kg/cm2 |

What was the Revolutionary bridges of Robert Maillart?
The Revolutionary Bridges of Robert Maillart Swiss engineer Robert Maillart built some of the greatest bridges of the 20th century. His designs elegantly solved a basic engineering problem: how to support enormous weights using a slender arch.
How big was Maillart’s first hollow box bridge?
For his 1901 bridge over the Inn River at Zuoz, he designed a curved arch and a flat roadway connected by longitudinal walls that turned the complete structure into a hollow-box girder with a span of 37.5 metres (125 feet) and with hinges at the abutments and the crown. This was the first concrete hollow-box to be constructed.
What did Robert Maillart do for a living?
His Salginatobel (1929–1930) and Schwandbach (1933) bridges changed the aesthetics and engineering of bridge construction dramatically and influenced decades of architects and engineers after him. In 1991 the Salginatobel Bridge was declared an International Historic Civil Engineering Landmark by the American Society of Civil Engineers .
Why did Robert Maillart make the arch so thin?
In this way, Maillart justified making the arch as thin as he could reasonably build it. His analysis accurately predicted the behaviour of the bridge but the leading authorities of Swiss engineering would argue against his methods for the next quarter of a century.
