Edgar Cardoso

 

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 23 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.

 

In 21 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 is 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, overMondego river in Figueira da Foz, over Kwanza river in Angola and over Limpopo river in Xai-Xai, as well as inMacau. 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 did not materialize, including the widening of the same bridge and a railroad bridge in the Arrábida Bridge, to substitute the bridge Maria Pia.
