SMARTE – Development and implementation of a long termstructural health monitoring

摘要

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