PTEC and Fastbridge Infravation project


Jesús Rodríguez, PTEC Managing Director and member of the Scientific Panel in EraNet Infravation visited in October 3rd the Jarama bridge located close to Madrid where a demo is being carried out by Dragados, with Tecnalia, Madrid Regional Government and other Fasstbridge partners.


This bridge was built in 1956 with a cross-section of two steel I beams and a top concrete slab. According to the structural code at this time, the design of this bridge did not take into account the fatigue limit state.


The demo includes the strengthening of some of the welded joints in the bottom flanges of the steel beams with CFRP laminates that are being applied with new developed epoxy resin in order to improve the fatigue performance of this bridge.


Numerical calculations before and after strengthening complemented with some on-site load tests are being carried out.
