Numerical Assessment of an Innovative RC-Framed Skin for Seismic Retrofit Intervention on Existing Buildings

The seismic safety of existing building stock has become a very critical issue in recent years, mainly earthquake-prone South Europe where most the buildings were designed before enforcement standards. Therefore, concept, development and testing efficient cost-effective retrofitting technologies are nowadays strongly needed, both for society scientific community. This study deals with assessment new RC-framed skin retrofit intervention buildings, evaluated through nonlinear static (pushover) analyses. A preliminary description proposed technology is provided, then numerical modeling typical RC after performed within OpenSees framework. results revealed that improves performance building, also modifying failure mode from brittle soft-story mechanism to more ductile one. presented study, dedicated structural aspects system, part TIMESAFE research project, thermo-hygrometric acoustic performances achievable by investigated.
