The crossbar in bridges are the supports between the beams. The main damage was observed in the earthquake of February 27 corresponds to bridges that do not contain in its design this support between joists , in an earthquake the first beam is receiving the full impact .
In much of the damage observed in bridges an excellent solution to repair the damaged beams is using carbon fiber , the methodology is to determine the loss bearing capacity , which will be covered with the structural reinforcement fiber carbon, same methodology used in the case of beam. The damage is quantified , the beam is reconstructed and is reinforced with carbon fiber.
Finally the crossbar is built and the bridge is at an optimum level of security for its implementation in the shortest time possible.
