Objective:

Composite structures are widely used in building construction in seismic areas. The project aims at defining innovative steel-reinforced concrete hybrid systems for the construction of feasible and easily repairable earthquake-proof buildings, exploiting the best properties of both steel and concrete constructions. For the purpose of this project, hybrid coupled shear walls (HCSW) and steel frames with reinforced concrete infill walls (SRCW) presenting optimized characteristics have been considered. The new systems have been applied to case studies and their effectiveness has been assessed. Finally, a complete design methodology has been proposed for each system.
