Seismic design of innovative steel frames with partially‐prefabricated infill walls

Hybrid steel and concrete seismic-resistant systems made by frames with reinforced infill walls (SRCWs) have potential advantages over structural solutions only or (RC). In fact, the high initial stiffness of is useful to minimize damage non-structural elements under frequent (low moderate) earthquakes while ductility dissipative capacity allow good performances rare (high-intensity) events. Eurocode 8 considers SRCW behave essentially as RC walls. However, numerical analyses on SRCWs, designed according Eurocodes, pointed out an unsatisfactory seismic behaviour discrepancies between assumed in design simulated response actions. Indeed, idea stiffening a frame leads complex mechanisms that are difficult control being affected many variables. this study, some recent developments for innovative transferred hybrid partially-prefabricated infills. Numerical models analysed understand global considered SRCWs provide preliminary validation proposed solution.
