STRUCTURAL MONITORING SYSTEM The use of Accelerometers for Structural Analysis

Resumo

due to the high investment for construction, the major disorders and risks that involve the
maintenance of Special Artworks (OAE - Obra de Arte Especial in Portuguese), increases the
importance of monitoring the performance of these works to ensure the project has been adequacy of
the project to the actual conditions of service. Monitoring the performance of these structures ensures
planning to aim to prolong the average times between maintenance and decreasing repairs downtime.
This study seeks to analyze the movements of arrows at a viaduct stringer, verifying its behavior
compared to that specified in structural previous design. The applied methodology consists in the
implantation of sensors in part of the structure, aiming to capture the displacement caused by the bending
moment. The results are aimed at the creation of computational modeling with the aid of a specific
computer program to compare the behavior of the viaduct loaded with data from the calculation
memorial with the data presented in the readings performed by the sensors of monitoring in a given
charging period.
