Josef Melan

Joseph Melan ( in the notation Josef Melan ) ( born November 18, 1853 in Vienna, † February 6, 1941 in Prague) was an Austrian civil engineer, on the back the Melan - construction after the Deflektionstheorie for arch bridges.

Melan - construction

Melan was a bridge builder and a professor at the Technical Universities in Vienna, Brno and Prague. He invented the Melankonstruktion, a new bridge construction with reinforced concrete ( " melan- construction ") that is particularly suitable for arch bridges.

A falsework made ​​of steel is embedded in concrete with and serves as a reinforcement. It is first built using the balanced cantilever as truss arch and receives on its underside a formwork. After concreting, it is an underlying steel insert for arch bridge. The special thing about it is the high rigidity of the reinforcement.

In this construction, numerous bridges in Europe (now the Czech Republic, Switzerland, Italy, Germany, Spain) and in the USA and Japan have been built. Melan received a patent for it in 1892, first as a design for ceiling constructions. The " First Austrian vault Committee " led 1893 experiments with it. It involved extensive exposure experiments on the former company premises of the contractor Pittel Brausewetter in Pressburg and especially in Brno, where Melan same time teaching at the Technical University and where he could work on the basis of the results obtained, the theoretical foundations of his " Melan - construction ".

Melan also influenced the American bridge building. David B. Steinman (1886-1960) translated Melans book The Bridge to English and developed it into a standard work on the hanging bridge on ( 1929).

One of his most famous pupils was Friedrich Ignaz Edler von Emperger.

In 1958 ( 22nd District ) was named after him in the Melangasse Vienna Danube city.
