In the present paper, developed inside the framework of the European Research project Rusteel, the behaviour of steel reinforcing bars under the combined effects of low-cycle fatigue action and corrosion phenomena is studied. The project aims at the definition of the effective ductility capacity of reinforcements, to be compared with the ductility demand imposed by earthquakes, investigated through the execution of non-linear dynamic analyses on numerical models of representative modern reinforced concrete buildings. The comparison between demand and capacity will enable understanding of the effective relationship between the requirements of earthquakes and the capacity of rebars (strength and ductility), providing indications for the design and structural details of new building in seismic areas.

The comparison between demand and capacity will enable understanding of the effective relationship between the requirements of earthquakes and the capacity of rebars (strength and ductility), providing indications for the design and structural details of new building in seismic areas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
