Teixeira Duarte – Engenharia e Construções, S.A. was present in the Reabilitar & Betão Estrutural 2020 Congress, held between 3 and 5 November 2021, at the Laboratório Nacional de Engenharia Civil (LNEC), in Lisbon.

This congress, organized with the support of the Laboratório Nacional de Engenharia Civil (LNEC), the Ordem dos Engenheiros (Portuguese Engineers’ Order) and the Ordem dos Arquitectos (Portuguese Architects’ Order), is a continuation of the National Meetings on Structural Concrete promoted biennially by GPBE and of the National Meetings on Structural Conservation and Rehabilitation (REPAR 2000 and Reabilitar 2010) organized by APEE. It intends to be a privileged forum for the dissemination and joint discussion of the topics usually treated separately in these two events, thus bringing together the most recent and innovative achievements in the field of structural concrete, as well as in the field of rehabilitation of structures of any type of material, namely masonry constructions or with timber, steel or concrete structure.

Among the various sessions of this congress, we highlight the presentation of the Rehabilitation of the Hercílio Luz Bridge in Florianópolis, Brazil made by Eng. João Pedro Lopes from Teixeira Duarte, who addressed the most complex and original technical aspects of this contract, from the strengthening of the foundations of the central columns to the entire procedure created for the replacement of the suspension elements of the central span – catenary and pendular cables – as well as the description of the technology used for the annulment of stresses in these elements (before replacement) and their reentry into load (after replacement) and the monitoring system implemented in order to measure, among other quantities, stresses and deformations of the structure, particularly during the critical operations of manipulating the deformation of the central span.
