AcronymANTISEISMIC STIRRUPS

Proposal titleNew industrial spiral stirrups in concrete reinforcement,providing better

antiseismic behaviour of buildings andconstructions. Optimisation and

Industrialisation.

AbstractA 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 industrialisation of the manufacturing process, as well as the

optimisation, 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,  sincethey protect the concrete from

expanding and fragmentising 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.
