The system of mediation of displacements in bridge decks based on cu00c9lula elu00c1stica

摘要

This invenu00c7u00c3o is an innovative system of measurement of displacements in bridge decks (1) whose design was supported by analytical calculations and prior research in laboratory and field.The system was developed to overcome some important limitations of technical clu00c1ssicas and presents as main advantages, compared with these alternative methods, the following: no need for access to people directly to the ground under the bridge; the possibility of performing mediu00c7 5 on courses of water assets.The invenu00c7u00c3o allows the measurement of displacements of bridge decks in load tests estu00c1ticos or almost estu00c1ticos. The system is of easy implementation and installation, not implying a acru00c9scimo costs compared to traditional solutions jumpy.The system designed is balanced on the size and capabilities of the equipment to provide cable steel (4), springs (3), load cells (2) and ensures precision levels compatible with the normal to requu00cdsitos applications envisaged.
