Resumo
[Abstract] A self-tensioning system that improves the behavior of elements under bending is described, from a resistant point of view such as deformations. The system is based in a force multiplying device tied in the opposite ends of the piece. Such device is activated with the loads which are transmitted to the supports, generating an eccentric tensioning force whose value varies with the magnitude of the applied loads. That tensioning force achieves an efficient redistribution of bending stresses. Different design parameters that determine the structural behavior of π-type section floors subjected to symmetrical and asymmetrical loads have been analyzed. The effectiveness shown by the system makes it especially interesting for its use in long-span structural floors with reduced depths.
