Everything about Edgar Cardoso totally explained
Edgar Cardoso (born 11th May 1913,
Resende - died 5th July 2000, Porto) was a noted
Portuguese civil engineer and university professor. In Portugal, Edgar Cardoso was a pioneer of experimental analysis of structures and of high precision instruments development for measure mechanical sizes in the little models and in his own works.
Early life
Cardoso was born in
Resende, and studied
civil engineering at the
University of Porto, in
Porto, where he graduated in 1937. In 5th of August 1935 Edgar Cardoso received a guideline to carry through its first period of training in the
Port of Leixões, for the study of the engineering works performed on the Port under the authority of engineer Gervásio Leite. The Cardoso's report entered in the university on 23rd October, and was appreciated and classified with a 16 points grade (out of 20) by the professors Teotónio Rodrigues and Antão de Almeida Garrett. Edgar Cardoso still carried out at least one other period of training in
Bragança in the JAE (national authority for the Portuguese roads), already in 1937, the year he graduated in
civil engineering from the
Faculdade de Engenharia da Universidade do Porto. Another notable academic document from the years he was a student was the report of a practical work that consisted of the full calculation of a swimming pool.
Work
In 21st December 1954, Edgar Cardoso began his university teaching career in
bridge building at the
Instituto Superior Técnico (IST), the biggest Portuguese school of
engineering, which belongs to the
Technical University of Lisbon. He became a noted professor for many generations of civil engineers who graduated at the IST.
Among the bridges that he designed, is the Mosteirô bridge that's the continuous truss frame beam and the S.João railway bridge, a continuous structure with thousand metres of length. He still made portico shape bridges, suspended bridges, over Zambeze and Save rivers in
Mozambique, and trussed beam bridges, over
Mondego river in
Figueira da Foz, over
Kwanza river in
Angola and over
Limpopo river in
Xai-Xai, as well as in
Macau. In the big span concrete arcs, as in Arrábida bridge (
Porto), and in re-reinforced concrete porticos, as in S.João railway bridge, reached world records on that time. Since trussed beam bridges, as the Figueira da Foz bridge, the first Portuguese trussed beams bridge, until suspended bridges without rigidity beam, stabilized by the suspended cable and the inclination of kingpost whole rigidity, as in Zambeze bridge, Edgar Cardoso branded by the difference the structures engineering evolution. The Macau Taipa bridge was a challenge by the shape, by the provocation of a convex superstructure. The exceptionality of the big sizes is the expression of your last interventions, as the S.João bridge and the runway Funchal airport extension.
Beyond the two great bridges projected by him, Edgar Cardoso made some interventions on the bridges of
Porto. A reformulation of the upper tray of Luis I Bridge and two projects that didn't materialize, including the widening of the same bridge and a railroad bridge in the Arrábida Bridge, to substitute the bridge Maria Pia.

Blessed with an extraordinary manual ability and solid theorical background, Cardoso constructed models of his structures and through them measured, many times with methods or devices invented by him, the necessary parameters to the evaluation of the structural behavior.
