SMARTE – Development and implementation of a long termstructural health monitoring

摘要

The accompanying of civil infrastructures behavior during their whole life cyclernis growing within the last few years. This fact is due to several problems detected in such structures,rnwhich is the main reason for the dispended budget by owners in their maintenance, beingrneven higher than other costs. In another way, traditional surveillance techniques, although importantrnare expensive, slow in time and subjective. Considering such panorama, within a nationalrnresearch project - SMARTE project - a new technique for management and maintenancernof structures was developed and implemented in a real structure, a pre-stressed concrete bridgern(Sorraia River Bridge). The developed technique, long term structural health monitoring, has asrna final purpose the execution of structural maintenance in an objective and efficient way. Thernevaluation of the structural behavior during whole life cycle is performed in an "on line" continuousrnway, allowing the on time detection of existent damages.
