New industrial spiral stirrups in concrete reinforcement, providing better antiseismic behaviour of buildings and constructions. optimisation and industrialisation.

Objective

A new type of industrial stirrup in concrete reinforcement is developed and laboratory tests have already proved its superiority during strong earthquakes. Main objectives of this project, will be the industrialization of the manufacturing process, as well as the optimization, experimental verification and validation of the proposed concept. Besides, alternative materials (FRPs) and different designs will be evaluated. The role of stirrups for the antiseismic strength of buildings is crucial, since they protect the concrete from expanding and fragmentizing and the rebars of the reinforcement from buckling and collapsing, what is proved to be the main failure mechanism of buildings during earthquakes. The developed stirrups are manufactured from a continuous wire, form consecutive windings along its longitudinal direction and house the rebars, with a pitch that may be uniform or variable. Because of their spiral continuous form, the axial load carried by the stirrups may continuously transmitted with no interruption across its length.
