Prestressed beam without load. Prestressed beam with load. Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. [1][2]: 3–5 [3] It was patented by Eugène Freyssinet in 1928.
Christian Menn. Christian Menn (March 3, 1927 – July 16, 2018) was a renowned Swiss civil engineer and bridge designer. He was involved in the construction of around 100 bridges worldwide, but the focus of his work was in eastern Switzerland, especially in canton Graubünden. He continued the tradition of and had a decisive influence on Swiss ...
Istanbul, Turkey. Died. April 5, 2018. (2018-04-05) (aged 87) London, England. Mete Avni Sözen (22 May 1930 [1] – 5 April 2018) [2][3] was Kettelhut Distinguished Professor of Structural Engineering at Purdue University, Indiana, United States from 1992 to 2018.
This method of construction is widely used for concrete structures, but the advantages of using similar techniques with stone are only just being realised.". [4] For concrete, this problem has been long solved: in addition to conventional tensile reinforcement, engineers developed prestressed concrete methods starting around 1888. Such tension ...

Moment redistribution in prestressed concrete continuous beams (1966) Michael John Nigel Priestley ONZM (21 July 1943 – 23 December 2014) was a New Zealand earthquake engineer. He made significant contributions to the design and retrofit of concrete structures, and developed the first displacement-based method of seismic design.
A prestressed concrete design method in which the prestressing forces exerted upon the member act to balance a given proportion of the service loads that the member will be subjected to.
