Long-Term Evaluation vs Short-Term Measurements : the Case of the Riddes Bridges
The case presented in the paper shows how effective measurements can be made to help in the assessment of an important structure in a relatively short time frame using a combination of electronic inclinometers, temperature sensors and hydrostatic leveling. While not directly applicable to all kinds of structures, the methodology presented can certainly be adapted to many situations. It is anticipated that this and similar methods will be developed that will deliver a high quality of information about structures, on the basis of which the management of bridges will evolve toward a decision process based on quality, accurate and verifiable data.
