Grafton Bridge: The Overseas Experts

The OVERSEAS EXPERTS

Emil Moersch (1872–1950) Reinforced-concrete theoretician.

Moersch was one of the most active of the early reinforced concrete pioneers in Germany.

He attended the Technical University of Stuttgart between 1890 and 1894.

He worked for the State of Württemberg as an engineer dealing intially with water and roads and then Railways and Bridges

He published the first and most authoritative theory of reinforced concrete in 1902.

**Der Betoneisenbau.

Seine Theorie und Anwendung. Konrad Wittwer:

Stuttgart, 1902.

The reinforced concrete structure, its application and theory.**

This work reappeared in 1906 as Der Eisenbetonbau and went through a total of five editions of increasing size until 1950.

From 1904–1908 he occupied the Chair of Concrete Construction at

Die Eidgenössische Technische Hochschule

(ETH) in Zurich.

In 1908 he returned to private practice in Germany and then to a position at Stuttgart University.

In 1929 he was awarded a Doctorate from ETH Zurich

In 1942 Moersch was awarded the Goethe Medal for Art and Science for his 70th Birthday.

Until his death in 1950 he was a member of the German committee for reinforced concrete.

In 1953 a newly built bridge in Berlin was named after him -

the Mörschbrücke, a road bridge over the Westhafenkanal in Charlottenberg-Wilmersdorf.

Since 1938 the German Concrete Association has awarded the Emil Morsch Medal to honor individuals who have distinguished themselves through outstanding achievements in the field of concrete construction.

Arthur Vierendeel (1852–1940)

Vierendeel was born in Belgium and graduated in 1874 with a Master of Science from the Université catholique de Louvain..

In 1885 he became Director for the Ministry of Public Works in West Flanders.

In 1889 he became Professor of Construction, Material Strength, and Structural Engineering at the Université catholique de Louvain.

His major published work, Cours de stabilité des constructions (1889) was an important reference work during more than half a century.

He was renowned for his work on the truss form that bears his name, the idea of which had first came to him in 1895

It was exhibited in the form of a bridge structure at the 1897 Worlds Fair at Brussels.

Although now not often used for Bridge construction the Vierendeel Frame is still commonly used for roof and floor support .

Vierendeel emphasised an importance of aesthetics over pure engineering
