Abstract—The paper offers a synthesis of the design study of
an advanced seismic retrofit solution of a low-rise reinforced
concrete building, consisting in the installation of a dissipative
bracing system incorporating pressurized fluid viscous
spring-dampers as passive protective devices. This
demonstrative application represents the last stage of the
research activities carried out by the authors on this protection
technology, also within several international Research Projects.
The structural characteristics of the case study building make it
representative of a large stock of similar edifices designed with
earlier Technical Standards editions, in Italy and other
European seismic-prone countries. The mechanical parameters,
dimensions, layouts and locations selected for the constituting
elements of the system, and the performance assessment
analyses in original and rehabilitated conditions carried out
according to a full non-linear dynamic approach, are presented.
The results of the analyses show a remarkable enhancement of
the seismic response capacities of the structure, which allows
reaching the high performance levels postulated in the retrofit
design.
